Molecular analysis of the F4 progenies obtained through pollen selection for heat tolerance in maize (Zea mays)

In the present study, three sets of F4 progeny lines developed through different cycles pollen selection for heat tolerance were studied genetic differences using 16 SSR markers during 2017–20 at Department Plant Biotechnology, University Agricultural Sciences, Gandhi Krishi Vignana Kendra, Bengaluru, Karnataka. Three groups progenies used study are GGG (pollen in F1, F2 and F3 generation); GCG only F1 CCC (no generation). Five randomly selected cross stress susceptible BTM4 tolerant BTM6 represented each group. The differed significantly number male parent alleles as evidenced by markers. (GGG) had more type compared to (GCG) (CCC) lines. recorded female other (GGG GCG) effectiveness towards increasing frequency their transmission succeeding has been demonstrated study.
