Abstract
To estimate the heterosis, general combining ability (GCA) and
specific combining ability (SCA) for resistance to powdery mildew, 30
F1 hybrids developed in a 6 · 5 line · tester mating design were
evaluated both under the greenhouse and field conditions. Predomi nance of non-additive variance over additive variance in the inheri tance of resistance to powdery mildew was detected. Inbred lines IIHR
681, IIHR 352, IIHR 190, RM 43, IIHR 121 and IIHR 122
demonstrated consistently high and negative GCA effects. There was
a strong correlation between GCA effect and mean per cent disease
index (PDI) of parent that would permit the use of the mean
performance of the parental lines to predict the value of a resulting
hybrid. Six hybrids, that is, Arka Jeet · IIHR 122, Punjab Sun ehri · IIHR 190, RM 43 · IIHR 121, IIHR 681 · IIHR 616, IIHR
352 · IIHR 616 and IIHR 352 · IIHR 718 which involved one or
both the parents with good GCA effects exhibited low mean PDI with
negative mid-parent heterosis and negative SCA effects.
