Heterosis and inbreeding depression were studied for
yield components in six hybrids of four parents. Significant
heterosis and inbreeding depression were estimated for traits
studied. The maximum heterosis of 111.6% were observed for
yield in hybrid D"A116-5-1x Kashmir Basmati. Cross combinations of Basmati 370 x DM16-5-1 and DM16-5-1 x DM107-
4 showed highly significant heterosis with a non-significant
inbreeding depression. The traits of other hybrids are also
discussed.
