ABSTRACTA field experirnent was carried out at the Rice Research Station in Al-

lg5nkhab/l{ajaf-iraq during 2010 growing season. The experiment wa1 laid in

three replication* u*ing systematic split plot design. Each replication involved

rs'o freatments of irrigation, alternate wetting and drying method (AWD) and

continuous$ flooded and rice genotypes (lr2r7 and 14)'vari-ous developmental characters have been studied, plant heightt

panicle^ length, tilhrJ/m2, panicle/m2, Tosterility, 1000-grain weightn seeds

rield/m' and seeds Yield/Plot.Result showed that there were no signilicant differences between

genogpes for all characteristics except Tosterility. {Jnder AWD^higher plant

i.octh increased (146,75 cm) while, ,q.WO produced lower tillers/m2 (231.75) and

panlcle/m2 (227.5) compare with continuously flooded.The interaction between the irrigation treatrnents and genotypes was

shona to affect panicle length, tillers/m2, panicle/mz and 7o sterility.
