ABSTRACT
The line x tester analysis using five lines and ten testers was carried out with a view to estimate of combining ability in pearl millet [Pennisetum glaucum (L.) R. Br.] for eleven different characters. The analysis of variance for combining ability revealed that the estimates due to testers (males) were higher than those of lines (females) for all the characters, except, number of effective tillers per plant, ear head length, 1000 grain weight, grain yield per plant, dry fodder yield per plant and harvest index. The estimates of variance ratio (?2gca / ?2sca) revealed predominance of non-additive gene action involved in expression of all the traits. The two parental lines ICMA 95222 and J 2511 were was the best general combiner for grain yield per plant which found promising for their exploitation in practical plant breeding. The hybrids viz., JMSA 20064 x J 2523, JMSA 20064 x J 2511 and JMSA 98444 x J 2511 expressed the significant sca effects for grain yield per plant.
Key words :
Combining ability, Gene action, Grain & fodder yield, Pearl millet hybrids.
