Abstract:   (5240 Views)
In order to study of the grain yield and its components in spring wheat genotypes affected by resources limitation under optimum condition, an experiment was conducted using split plot experiment in RCBD design with three replications in Agricultural and Natural Resources Research Center of Khouzestan-Iran in 2010-2011 cropping season. In this study, main plot were consists of six wheat spring genotypes and flag leaf removal, flag leaf removal + spike cover, spike covering and control were considered as sub plot. Results of analysis variance showed that difference of treatments and genotypes was significant for grain yield and number of spike/m2 at 1% level, Also interaction effect was significant for grain yield, harvest index, biomass, 1000- grain weight, number of grain/spike and number of spike/m2 at 1% level. Control treatment with 4113 (kg/ha-1) and also No. 4 genotype with 3970 (kg/ha-1) had the highest of grain yield. Result showed that with application of cultural management, cultivation of this genotype will be very successful in the region.
