To verify diversity, relationship between traits, and selection of superior genotypes using the selection index of ideal genotype (SIIG) technique, an experiment was carried out on agricultural land in Tikmeh Dash city, from the province of East Azarbaijan in 1396-1397. In this experiment, 22 autumn rapeseed genotypes were studied in a randomized complete block design with three replications for a number of morphological traits. 963, Okapi and Licord genotypes have the highest grain yield mean. Traits including, Grain yield per hectare (Y), single plant yield (YI), and number of pods per plant (NPP) had the highest Coefficient Variation Phenotype (CVP), indicating the effect of the environment on these traits. Coefficient Variation Phenotype (CVP) and Genotype (CVG) showed that genotypes have high genetic variation in some traits such as Grain yield per hectare (Y), single plant yield (YI), and number of pods per plant (NPP). Heritability was low for the Number of pods per main stem (NSP), Day to flowering (DFT), and Grain yield per hectare (Y) traits, however, it was high for the Day to ripe index (DRI), Bush height (H), and Day to pod (DPO) traits. Altogether 65.69% of the total variation was justified through the 5 factors that had been determined by the Factor analysis to the principle component. Based on the SIIG technique, the genotypes SW101, L83, HW101 and 963 with the highest SIIG values (0.710, 0.672, 0.6531 and 0.6530 respectively) were among the best genotypes. On the other hand, Zarfam, Talayeh, 957 and SLMO16 genotypes with the least amount of SIIG value (0.185, 0.243, 0.271 and 0.272 respectively) were among the weakest genotypes for most morphological traits. The genotypes of SW101, L14, 944, Okapi, and 963 both having high SIIG value and performance above total average, are the best genotype from the point of yield and other morphological traits. |
