COMBINING ABILITY FOR SOME DROUGHT TOLERANT CHARACTERS IN MAIZE (ZEA MAYS L.)

Published on Nov 04, 2019 03:13 AM

In a 7-parent diallcl of drought tolerant and susceptible inbreds of maize raised under
rain fed conditions over two years, only gca variance was significant for chlorophyll content,
only sca for pollen shed period and for other traits both gca and sca variances were
significant. The sca variances were predominant for grain yield/plant and stomata
number/mm2 of leaf area, whereas gca variances were predominant for germination leaf
area/plant, root length, root weight and root number. The inbreds H-98, CM-205, V55-B and
the crosses, VSO-B x CM-205, V20-B x V50-B, V57-B x A-654 and V2o-B X V57-B, were
identified as the best inbreds and crosses, respectively, for grain yield and drought tolerant
characters
