Abstract:
Thirty genotypes comprising of wheat (T. aestivum and T. durum) and hexaploid triticale was studied in Randomized Block Design with three replications under saline condition during 2016-17 to assess the variability, heritability and genetic advance of these genotypes for yield and its contributing traits. The treatment, i.e. mean sum of squares due to genotypes revealed significant differences for all characters studied revealing the presence of high genetic variability among the genotypes. The estimates of GCV were lower than the respective PCV; it means that the apparent variation is not only due to genotypes but also due to the influence of environmental factors on the expression of the traits studied. Characters like seed yield/plant, spike length, number of grains per spike, number of effective tillers and test weight showed high GCV, PCV, heritability coupled with high genetic advance as percent of mean, suggesting that selection for the improvement of these characters may be rewarding. High heritability estimates with expected moderate genetic advance were observed for the traits like biological yield and harvest index depicting the greater role of additive gene action in their inheritance.
