tailieunhanh - Combining ability analysis for yield and attributing traits in field pea (Pisum sativum L.)

In the present investigation 7 parents and 21 F1 hybrids of field pea were evaluated in a randomized complete block design in three replication to estimate combining ability of genotypes by using diallel fashion for the yield and yield attributing characters at instructional farm of Indira Gandhi Krishi Vishwavidyalaya, Raipur during the Rabi December 2017 to March 2018. Combining ability analysis indicated contribution of non additive gene effect playing an important role for most of the characters and the analysis of variance due to general combining ability (gca) and specific combining ability (sca) revealed highly significant for most of the characters. The parent Indira Matar-1 was recorded as the best general combiner for secondary branches per plant, seed per pod seed per plant and seed yield per plant. The crosses Aman x KPMR 400 was recorded as the best combiner for days to maturity, seed per plant, 100 seed weight, seed yield per plant and biological yield per plant. | Combining ability analysis for yield and attributing traits in field pea (Pisum sativum L.)
