ASSESSMENT OF COMBINING ABILITY, HETEROSIS AND GENETIC VARIANCE FOR FRUIT QUALITY CHARACTERS IN MUSKMELON (CUCUMIS MELO L.)

Published on

Combining ability, heterosis, and genetic variance for yield, maturity, and plant characters
in muskmelon
(Cucumis mew L.) were estimated through the use of six·par2nt dlaliel
during 1984-85. The sea·variance exceeded gca for all the traits. Durgapur Madhu was the
best general combiner for fruit yield. Punjab Sunehri had exceptional gca for the traits
associated with earliness, and WMR 29 combined well for vine length. Favourable
heterosis over midparent was observed for fruit yield, fruit number, fruit weight, fruit
bearing branches, node of first female flower, days to harvest, and vine length. The
estimates of dominance variance exceeded those of additive variance revealing
overdominance for most of the traits.
