Abstract

To study the inheritance of DROUGHT tolerance in traits in bread WHEAT, 7 cultivars of bread WHEAT with their F1progeny produced through a half diallel mating design, were planted in a randomized complete block design with 3 replications in normal and DROUGHT condition in Seed and Plant Improvement Institute Karaj, in year 2004. Analysis of variance showed significant difference for all the traits in normal and DROUGHT conditions at 1% probability level except for 2 traits (grain filling period and grain filling speed) in DROUGHT conditions. DIALLEL ANALYSIS revealed that general combining abilities were significant for all the traits in normal and DROUGHT conditions at 1% level of probability except for the number of spikes in plant in DROUGHT condition. The specific combining abilities were significant for all the traits at 1% level of probability except days to maturity in the two environments. Additive and non - additive effects were effective in controlling all traits and increase in the most of the traits was controlled with dominant alleles. Two traits (number of fertile spike lets, extrusion peduncle length) and grain yielding spikes exhibited the most broad sense in normal and DROUGHT conditions respectively.
