GENETIC ARCHITECTURE OF SOME QUANTITATIVE CHARACTERS IN COMMON WHEAT

Abstract

rive generations involving P1, P2, F1, F2 and F3 were studied for six quantitative characters, viz., tillers/plant, ear length, grains/ear, yield/ear, yield/plant and 100-grain weight in five common wheat crosses namely, CAPAN 1962 x CC 493, CAPAN 1961 x MUW 27, CPAN 1933 x HW 517, CPAN 1959 x HUW 1 and WH 147 x CPAN 1874. Both scales (C and D) were significant in all the crosses for majority of the characters therefore, non-allelic interaction (i) and (1) type existed; (d) and (i) were more important.

Keywords: Wheat, Genetic Architecture, Quantitative Characters
