Figure S1: Annual average spring temperatures in German cities. The upper panel depicts the annual average springtemperature, i.e. the mean of the months March, April, and May, from 1953 to 2009 in Gatersleben, where the ex-situ
Genebank of Germany is located. Linear regression detects an average increase in the annual average spring temperatureof approximately 1.5◦C. The lower panel depicts the annual average spring temperatures of ten meteorological stations andtheir geographical location within Germany (blue dots) in relation to Gatersleben (green square). The stations were selectedto uniformly cover Germany. Linear regression shows a similar trend of increasing spring temperatures as with Gatersleben.Meteorological observations were kindly provided by the German Meteorological Service (www.dwd.de). Plots were createdwith R (http://r-project.org).

Figure S2: Relationship between flowering time and average spring temperature for barley and wheat for each species andeach annuality. In the left panel, flowering time is plotted in boxplots in black, whereas the red curve plots the average springtemperature. Analyzing the trend in flowering time, the cumulative distribution of flowering time (FTi) for each decade isillustrated in the right panel. Comparing the median flowering time of the decades (dashed line in right plots), a shift ofup to 20 days earlier flowering time was observed (red curves in right panel). The table below summarizes the correlationbetween flowering time and average spring temperature for each species and each annuality. A negative correlation betweenflowering time and spring temperature was found, which is associated with the shift of the flowering time in recent years.Plots were created with R (http://r-project.org).

Figure S3: Validation of the mean and NRP for flowering time of winter wheat. All pairs (a, b) of winter wheat accessionswere considered that were cultivated together at least in two years. In addition, mean and NRP yield contradicting ranks,i.e., the mean of a was smaller than the mean of b and the NRP of a was bigger than the NRP of b. Based on the repeatedcommon cultivation, the real flowering time was evaluated indicating that the NRP is less biases than the mean. The plotwas created with R (http://r-project.org).

Figure S4: (A) MTO for a large winter wheat collection based on the normalized traits of flowering time (NRP FTi),plant height (NRP PH) and thousand grain weight (NRP TGW). Two accessions with contrasting phenotypes have beenselected as indicated by the red and the green star. The red star is an early flowering short accession with high thousandgrain weight, while the green star is a late flowering tall accession with low thousand grain weight. (B) and (C) visualizethe recorded pre-normalized trait values of each year of multiplication by a histogram and display the ranks for the twoselected accessions by red and green lines respectively. Missing histograms indicate missing phenotypic observations. Plotswere created with R (http://r-project.org).

Figure S5: Visual representation of the correlations between NRPs of agronomically important traits. For each species and annuality the figure depicts the pair-wisecorrelation coefficients (CC) between NRPs (NRP) of the traits: flowering time (FTi), plant height (PH), and thousand grain weight (TGW). For each hexagonal bin thenumber of plant samples assigned to this bin is represented by the color. The color of the bins ranges from light green, which represents a low number of samples, to violet,representing a high number. A significant positive correlation was found between flowering time and plant height as well as between plant height and thousand grain weight.However, no common trend is apparent for flowering time and thousand grain weight. Plots were created with R (http://r-project.org).

Supplementary Text A: Dependencies among phenotypic traits 39
Based on the NRP applied to phenotypic and passport data from the Federal Genebank of 40
Germany, the data was investigated for dependencies that would hinder a simple 41
selection of promising plant samples. 42
The relations between the three important agricultural traits, flowering time, plant height 43
and thousand grain weight, were investigated. Initially, the pair-wise relation between 44
their normalized values were visualized and the �-value was computed using Spearman's 45
rank correlation1 (Fig. S5). 46
Investigating these pair-wise correlations, two global trends were found in comparing the 47
results for barley and wheat as well as winter and spring types. On the one hand, 48
flowering time has a significant positive correlation with plant height indicating that 49
plants with early flowering time have a tendency to be shorter than plants with a later 50
flowering time, which has been reported previously for small collections2,3. One plausible 51
explanation is that barley and wheat plants stop their stem elongation at growth stage 52
Z714 which may explain why early flowering plants tend to be shorter. 53
On the other hand, plant height has a significant positive correlation with thousand grain 54
weight, indicating that short plants tend to have a lower thousand grain weight than taller 55
plants. The positive correlation between plant height and grain yield in wheat has been 56
known for many years5, where the authors concluded that tall cereal plants would tend to 57
have a greater biomass than shorter plants and that the amount of biomass might be 58
correlated with the productive potential and final grain yields. In physiological terms tall 59
wheat plants would tend to provide a greater `source'. With the introduction of the 60
gibberellic acid insensitive semi-dwarfing genes in the 1970s it became clear that the 61
reduced plant height is pleiotropically linked with a reduced thousand grain weight6,7. 62
Comparing the absolute values of the correlations, a much stronger correlation was 63
observed between flowering time and plant height than between plant height and 64
thousand grain weight. 65
The case of flowering time and thousand grain weight is a completely different situation. 66
This correlation is close to zero and not significant for winter wheat. The weak but 67
significant negative correlation for spring types might be explained by the observation 68
that early flowering accessions can start to fill their seeds earlier and hence might utilize 69
available water more efficiently before drought. In contrast, winter types flower earlier in 70
the year than spring types (Fig. S2) and they start to fill their seeds earlier. For this 71
reason, drought is more critical for spring-sown types than for autumn-sown types. In 72
addition, wheat typically flowers later than barley and therefore it is more likely to be 73
exposed to drought irrespective of spring or winter type. These observations indicate that 74
drought affects the yield (thousand grain weight) of spring types in Germany which 75
emphasizes the need for well-adapted crop cultivars even in temperate zones. 76

Supplementary Text B: Dependencies of phenotypic and passport data 78
Dependencies between the selected traits and passport data were found in the collection 79
of the IPK Genebank. First the samples were grouped according to their country of origin 80
as maintained in the passport data. From there, the focus was placed on larger regions 81
gathering all accessions from countries of a given region into one set. Regions were 82
chosen to be represented by at least 50 accessions recorded in at least three years. 83
Dependencies between the normalized trait distributions within each of these regions 84
were investigated, under the environmental conditions of Gatersleben. Fig. S6, presents a 85
scatter plot of the NRPs of flowering time and plant height. 86
At first glance, large differences were found among the distribution of traits for different 87
regions. The most striking differences are the late flowering time of accessions from 88
Europe in comparison to the remaining regions and the short plant height for accessions 89
from West, South and East Asia. Remarkable differences were also found between 90
neighboring regions, for instance, between Europe and the Mediterranean Basin. 91
To confirm these observations, the Kolmogorov-Smirnov test was used, with a 92
significance level of 0.01, for the pair-wise comparison of the equality of the distributions 93
of NRPs for flowering time and plant height. For flowering, we found that the regional 94
distributions differ significantly, with the exception of the comparison of North America 95
and the Mediterranean Basin. Likewise for plant height, we found that the distributions of 96
the regions differ significantly, with exceptions for North and Central Asia and Europe as 97
well as North and Central Asia and North America. 98
These observations indicate that the accessions have been selected and adapted to the 99
environmental conditions of their country of origin. This adaptation leads to considerably 100
different phenotypes even under the environmental condition of the ex situ seed bank 101
location. Based on the substantial differences among the regions of origin, we found no 102
evidence that the few years of cultivation in Gatersleben have caused considerable 103
adaptation towards the local environmental conditions of the ex situ seed bank. 104
The fact that these regional differences are still detectable is due to the inbreeding 105
character of barley and wheat. In case of landraces (Landraces are traditional 106
domesticated populations of locally adapted genotypes.) that originally represent mainly 107
mixtures of genotypes, the splitting of phenotypically and phenologically heterogeneous 108
populations in more homogeneous subpopulations represents an essential constituent of 109
the conservation procedure of the Gatersleben seed bank. In this way selection effects can 110
be efficiently minimized8. 111
Summarizing these findings, there is an inherent and intrinsic structure in the C & E data. 112
Independent of the rationale behind them, we conclude that this will hamper manual 113
selection of plant samples to completely explore the collection. Hence, computer-assisted 114
methods for trait-based selection of accessions will gain great importance. 115

Supplementary Text C: Polymorphisms at the Ppd-D1 locus 116
Previously, five polymorphisms at Ppd-D1 were identified by partially or completely 117
resequencing the locus in wheat: ‘Chinese Spring’ (DQ885766), ‘Mercia’ (DQ885768), 118
‘Norstar’ (DQ885770), ‘Ciano 67’ (DQ885767), and the wheat wild D genome donor 119
Aegilops tauschii (DQ885771)9. Recently, genotyping 492 wheat varieties and 55 120
samples of Ae. tauschii revealed 5 polymorphic positions defining four haplotypes for 121
bread wheat and two haplotypes for Ae. tauschii10 (Tab. S5). 122
In our study, targeted resequencing at Ppd-D1 in a much small number of selected 123
genebank accessions revealed seven polymorphisms – which defined seven haplotypes (I, 124
II, III, IV, VII, VIII, IX) or seven alleles (Ppd-D1a, Ppd-D1b, Ppd-D1c, Ppd-D1d, Ppd-125
D1e, Ppd-D1f). 126
Among them, alleles previously known were I) the reference allele Ppd-D1b 127
(DQ885766); II) Ppd-D1a - harboring a 2kb deletion in the promoter region 128
(DQ885767); III) Ppd-D1c - harboring an insertion of a transposable element in intron 1 129
(DQ885768), and IV) Ppd-D1d - harboring a 5bp deletion in exon 7 (DQ885770)9,10. In 130
addition, one SNP [G/A] in exon 7 was found9. All resequenced samples harbored the 131
nucleotide A in contrast to ‘Chinese Spring’ (DQ885766) (Tab. S5). The remaining three 132
alleles found in our study are novel and include SNPs as well as one deletion. In exon 5, a 133
deletion of AT was observed in plants of accession 44 (TRI11658, collected in Pakistan, 134
Tab. S2) defining the allele Ppd-D1g (Tab. S5). This deletion affected the first two bases 135
of the codon ATA and led to a frame-shift and a premature stop codon 10 bases 136
downstream. In exon 6, a SNP [C/T] was observed in plants of accession 39 (TRI11693, 137
collected in Pakistan) leading to a mutation from the codon CGA to the stop codon TGA 138
(Ppd-D1f) In analogy to the known 5bp deletion in exon 7, both polymorphisms leading 139
to premature stop codons were located upstream of the CCT domain. In addition, a SNP 140
[T/C] was found in the 3’-UTR of accession 20 (Ppd-D1e) (Tab. S5). In summary, seven 141
haplotypes/ alleles were found in the collection of 60 accessions. In total, eleven plants 142
were heterozygote and harbored haplotype combinations I/II (9 individuals) or II/III (2). 143
It is interesting to note, that three allelic states were discovered for photoperiod-144
insensitive materials: haplotype I (Ppd-D1a), haplotype II (Ppd-D1b) and heterozygous 145
I/II ( Ppd-D1a/ Ppd-D1b). 146
