Studies on genetic variability, heritability and genetic advance in fenugreek (Trigonella foenum-graecum L.) germplasms grown under the Malwa region of Madhya Pradesh, India

Abstract

An evaluation of eighteen germplasms was conducted in Rabi season2020-21 using Randomized Block Design with three replicationsatDepartment of Plantation, Spices, Medicinal and Aromatic Crops, Collegeof Horticulture, Mandsaur, Rajmata Vijayaraje Scindia Krishi VishwaVidyalaya (M.P.). The phenological characteristics of 18 germplasmshowed that G - MDF-2 took the least amount of time for 50 % flowering3(45.33 days), 50 % pod setting (53.67) and days to maturity (116.00) ascompared to other germplasm. However, G -Suraj had maximum plant13height (10.34, 24.61, 49.99 and 92.18 cm) but G -Sehore-12 had highest10fresh weight (2.27, 9.67, 29.09 and 52.45 g), dry weight (0.32, 3.32, 18.55and 23.16 g), number of branches (4.33, 7.10, 10.80 and 14.57), leaf area(131.59, 572.17, 1629.65 and 711.84) and leaf area index (1.09, 3.54 and3.9) at 30, 45, 60 DAS and at harvest respectively. Whereas, G -Sehore-1012 had highest number of pods (34.57), number of seeds (22.20), podlength (12.07 cm), shelling % (72.63), seed yield (27.17) and harvest index(43.37). While, G -Sarayu had maximum test weight (17.47 g). The highest18GCV(21.01) and PCV (30.29) were observed for leaf area. Although, thehighest heritability was recorded in plant height (70.66) and test weight(64.55). The highest genetic advance was recorded in leaf area (139.15)and plant height (14.66). Whilethe highest genetic advance as a percent ofmean was observed in leaf area (30.03) and leaf area index (27.80).Out ofeighteen studied germplasms, the highest yield was recorded in G -10Sehore-12 followed by G -Shree and G -Lajwab.
