Study on association analysis for gum content in clusterbean [Cyamopsis tetragonoloba (L) Taub] genotypes Sivia Sukhdeep Singh*, Kamboj Naval Department of Genetics and Plant Breeding, CCS Haryana Agricultural University, Hisar-125004, Haryana, India *Email for correspondence: sukhdeepsinghsivia@gmail.com
Online published on 6 December, 2021. Abstract Field experiment was carried out in the forage section of Department of Genetics and Plant Breeding, CCS Haryana Agricultural University, Hisar, Haryana during kharif 2012. Thirty three genotypes of clusterbean were evaluated for various biometrical traits. All the genotypes were grown in randomized block design with three replications under rainfed conditions. The study helped in identifying the characters mainly contributing to the gum content. A critical perusal of correlation coefficients revealed that the gum content was positively and significantly associated with 100-seed weight while days to maturity and plant height had negative association. Pod length and number of seeds per pod were significantly correlated. Path coefficient analysis revealed that 100-seed weight had positive and high direct effect on gum content followed by number of seeds per pod and plant height. The results of the present study suggested that selection based on the 100-seed weight might bring improvement in gum content in clusterbean. Top Keywords Clusterbean, Correlation, Path analysis, Direct effect, Gum content. Top | | |
