Abstract

In order to investigate the type of gene action and heritability for seed PROTEIN percent, seed PROTEIN yield and some other traits in bread WHEAT, seven cultivars namely, Atrak, Khazar, Tajan, Falat, Bezostaya, Golestan and Mahdavi were intercrossed in a half DIALLEL fashion. Parents and their progenies were planted in a randomized complete block design with three replications in normal and DROUGHT STRESS conditions. Analysis of variance indicated a significant difference among genotypes for all traits in either condition. Griffing & Hayman-Jinks procedures were employed to analyze the data. Analysis of general and specific combining abilities (GCA & SCA) was done using Griffing method (II). Mean squares of GCA & SCA were significant for all characteristics in both normal and DROUGHT STRESS conditions, showing additive and non-additive effects control of these characteristics. On the other hand, the results show that seed PROTEIN percent is controlled by only additive effects while additive and non-additive effects control yield and seed PROTEIN yield. Regression coefficient (b) wasn't significantly different from 1, that shows the results are corrected. Narrow-sense heritability estimates ranged from 21% to 67% with plant height having the highest estimates. The estimates of narrow-sense and broad-sense heritability for seed PROTEIN percentage (59% & 78% respectively) indicated the effectiveness of selection for this trait. But the narrow-sense heritability ranging from 21% to 26% for seed PROTEIN yield in normal and drought conditions shows that there isn't much expectation in the effectiveness of selection for it. The results indicate that seed PROTEIN percentage is controlled by additive effects but additive-dominance model can be appropriate for yield and seed PROTEIN yield. A comparison of banding patterns resulted from the ELECTROPHORESIS of seed storage PROTEINs under normal and DROUGHT STRESS conditions revealed that DROUGHT STRESS had no effect on the banding patterns and it was only bands densities that were affected.
