Abstract

Investigation was undertaken during kharif 2022 at Agricultural Research Station, Ananthapuramu to analyse sixteen genotypes of Redgram (Cajanus cajan L.). The primary focus of the research revolved around conducting correlation studies and examining genetic diversity in seed yield and its associated characteristics. Significant variability was noted in all the parts being inspected. The coefficients of variation for productivity metrics, including seed yield, number of pods/ plant, number of branches / plant and 100 seed weight, were notably high. Considerable variation was seen in the days to 50% blooming, plant height, pod length and number of seeds / pod. The inquiry found that the evaluated qualities showed substantial heritability and a considerable expected genetic advancement. The independent variables, which included plant height, number of branches / plant and number of pods/ plant had a strong positive correlation with the dependent variable, seed yield. Plant height, days to 50% blooming and 100-seed weight were shown to have the most significant direct impact on seed yield, according to an examination of correlation coefficients among several characteristics impacting seed yield.

Conclusion

Upon meticulous analysis of character association and path studies, our investigation of sixteen genotypes of Redgram (Cajanus cajan L.) during the kharif season of 2022 at Agricultural Research Station, Ananthapuramu, has provided valuable insights into enhancing redgram seed yield. The study focused on conducting correlation studies and evaluating genetic diversity in seed yield and associated traits. The research unveiled significant variability across all examined parameters, highlighting the potential for targeted trait selection to improve seed yield. The coefficients of variation for key productivity metrics, including seed yield, number of pods/plant, number of branches/plant, and 100-seed weight, were notably high, indicating substantial diversity among the genotypes. Notably, traits such as days to 50% blooming, plant height, and number of pods/plant exhibited both high heritability and considerable genetic advance. These traits, characterized by their heritability and genetic advance, emerge as promising candidates for targeted selection to enhance redgram seed yield. The correlation analysis revealed strong positive associations between seed yield and independent variables such as plant height, number of branches/plant, and number of pods/plant. Furthermore, our path analysis identified specific traits, namely plant height, days to 50% blooming, and 100-seed weight, with the most significant direct impact on seed yield. These findings provide a comprehensive understanding of the key determinants influencing redgram seed yield, paving the way for informed breeding strategies.
