GENETICS OF SOME IMPORTANT CHARACTERS USING LINE X TESTER ANALYSIS IN MUSKMELON

Published on

Sixty Fl hybrids involving three females, viz. M 221, M 225 and W 321 and twenty males
were produced in muskmelon (Cucumis melo) in a line X tester design. Eight economic
characters contributing to earliness, fruit yield and sweetness were studied. Analysis of
variance for combining ability revealed that MS due to gca lines (except TSSO/.), gca testers
and sca hybrids were highly significant for all the characters studied. Magnitude of gca
lines was greater compared to the other two components. W 321 among lines and H 172
among testers were good general combiners for majority of characters. Among the crosses,
M 221 X N 231, M 225 X A 102, M 225 X M 224, M 225 X F 143, W 321 X M 222 and W 321 X N
233 combined well to produce significant desirable sca effects for days to picking, yield per
plot and TSS%. Cross W 321 X N 233 outyielded Punjab Hybrid (check) by more than 50%
and was also significantly earlier than Punjab Hybrid.
