Abstract: 

Eleven genotypes along with one check variety of Pigeon pea (Cajanas cajan) were evaluated under the research field of Genetics and Plant Breeding Medziphema, Nagaland during kharif season 2017-2018. Data were recorded on nine quantitative characters and the analysis of variance revealed significant differences among genotypes for all characters, indicating high degree of variability present in the material. The maximum genotypic variance was observed for secondary branches per plant followed by number of pods per plant. High phenotypic variance was also observed for secondary branches per plant followed by number of pods per plant. The high estimates of genotypic and phenotypic coefficient of variation were obtained for number of pods per plant highlighting the presence of wider genetic variability for this character. Secondary branches per plant revealed maximum heritability estimates followed by number of pods per plant, days to 50% flowering and days to maturity. Genetic advance as percentage of mean was recorded highest for number of pods per plant followed by secondary branches per plant and primary branches per plant. High heritability along with high genetic advance were observed for primary branches per plant, secondary branches per plant and number of pods per plant suggesting additive gene action for these characters.
