Title : Assessment of genetic variability and character association in fenugreek under Jabalpur condition of Madhya Pradesh

Abstract :

An experiment was carried out during 2018-19 at the Vegetable research farm, Department of Horticulture, College of Agriculture, Jawaharlal Nehru Krishi Vishwavidyalaya, Jabalpur, Madhya Pradesh, with 17 fenugreek germplasms as a part of AICRP on Spices. The genetic variability analysis was carried out with the biometric data obtained. Five plants from each replication are randomly selected to record the biometric observations namely plant height, days to flowering, number of branches plant-1, number of pods plant-1, pod length and seed yield plant-1. The PCV was higher than the corresponding GCV for all the traits under study, including the seed yield. In our study, number of pods plant-1 (44.61%), seed yield plant-1 (41.06%) and number of branches plant-1 (30.46%) showed higher GAM along with higher broad sense heritability. These traits are perhaps under the control of additive gene action and selection for these traits would be effective. The genotypic and phenotypic correlation coefficient between days to first flowering and seed yield plant-1 (0.74 and 0.48) were positive and significant. A direct selection for earliness would improve the seed yield plant-1. The phenotypic correlation coefficient between the number of pods and seed yield plant-1 (0.41) was positive and significant. The phenotypic correlation between the number of branches plant-1 and seed yield plant-1 (-0.38) was significant yet in negative direction. The genotypic path analysis revealed that the plant height and branch number indirectly influenced the seed yield.
