Item Combining ability analysis in cowpea (Vigna unguiculata [L| walp)(Kerala Agricultural University, 1998) Sobha, P P; Abdul Vahab, M; Krishnan, SCombining ability was studied in a 10 x 10 diallel cross in cowpea for nine important characters. The variance due to general combining ability and specific combining ability showed both additive and non-additive gene action for plant height, primary branches, days to flowering, pod length, pod weight, pods per plant, seeds per pod, 100 seed weight and yield per plant. Among ten parental lines, Arka Garima, VU-18, Selection 2-1, Section 263, Pusa Komal and Kanakamoni were good general combiners for most of the yield components. The hybrids VU-18 x Arka Garima and Selection 2-1 x VS 389 possessed high specific combining ability effects for yield per plant.Item Genetic variability, heritability and genetic advance in cowpea (Vigna unguiculata [L.] walp)(Kerala Agricultural University, 1998) Sobha, P P; Abdul Vahah, MGenetic variability studies in thirty one genotypes of vegetable cowpea revealed significant difference for all the characters except primary branches. A wide range of phenotypic coefficient of . variation (7.4 to 56.7) was observed. High genotypic coefficient of variation was observed for pod weight (54.6) and pod yield per plant (53.1). All the characters exhibited high heritability (78% to 97%). Heritability and genetic advance were high for pod weight and yield per plant, which can be relied up on for the effective genetic improvement of cowpea.
