GENETIC ARCHITECTURE OF METRIC TRAITS IN WHEAT (TRITICUM AESTIVUM L. EM. THELL)

Abstract

Six generations Le. PI, P2, F1, F2, BC1 and BC2 of three cross combinations viz., CPAN-1866 x HD-2009, CPAN- 1866 x DL-153-2 and CPAN-1959 x DL-153-2 were grown in a randomised block design with three replications at the Research farm of Meerut University, Meerut, in 4m long rows spaced 30 cm apart. Plant to plant distance within a row was 10 em. Observation on plant height (cm), e~r length (cm), spikelets per ear, grains per ear, grain weight per ear (g), tOoo-grain weight(g) and grain yield per plant (g), were recorded on five randomly selected plants. The data ':.ollected on seven quantitative traits were computed for each generations of all the crosses. The genetic parameters were estimated following Jinks and Jones [1].
