Assessment of Genetic Variability to Contribute Yield and its Components Characters in Pigeonpea [Cajanus cajan (L.) Millsp.] Genotypes in Central Plain Agro-Climatic Region of Uttar Pradesh, India

Abstract

The present investigation entitled “assessment of genetic variability to contribute yield and its components Characters in Pigeon pea [Cajanus cajan (L.) Millsp.]” genotypes in central plain agro-climatic region of uttar pradesh”was conducted at Oilseed Research Farm, Kalyanpur, C. S. Azad University of Agriculture and Technology, Kanpur- 208002 (U.P.) during kharif season 2021-22. Genetic variability studies were carried out for 34 pigeon pea genotypes during the years 2021-2022. The analysis of variance revealed that there was significant amount of variation for all the characters during these years. Days to maturity, plant height, number of secondary branches, days of 50% flowering, 100 seed weight, number of primary branches, biological yield, seed yield per plant, harvest index, number of pods per plant and number of seeds per pod was shown to have identified as high heritability value. High estimate of (phenotypic coefficient of variance and genotypic coefficient of variance) PCV and GCV were observed for the number of secondary branches, number of primary branches and days to maturity while moderate estimate of PCV and GCV were observed for plant height, 100 seed weight, days to 50% flowering, seed yield per plant, number of pods per plant and harvest index. The character association studies revealed that at genotypic and phenotypic level, seed yield per plant had positive and high significant correlation to harvest index, days to maturity, biological yield, 100 seed weight and number of pods per plant.
