Genetic Analysis of Heterosis of F1 Seed Yield and Quality Attributes in Fenugreek (Trigonella foenum graecum L.)

A diallel set of 10 parents and their 45 F1 hybrids developed through diallel mating design (excluding reciprocals) were analysed to estimate the magnitude of heterosis for seed yield and its component in fenugreek. The present study was conducted at Main Experimental Station, Department of Vegetable Science, Acharya Narendra Deva University of Agriculture and Technology, Narendra Nagar (Kumarganj), Ayodhya (UP), India, during Rabi, 2020-21 (Y1) and 2021–22 (Y2). Appreciable heterosis were found over better parent and standard variety for all the traits under study in desirable direction. For early maturity traits i.e., days to 50% flowering, days to maturity negative heterosis is desirable, for these traits cross combinations P1× P2, P2×P5, P1×P10 and P5×P9 exhibited highest significant heterosis over better parent and standard variety. Seed yield per plant being a compound trait and is a multiplicative product of several basic component characters of yield. The top three hybrids based on seed yield per plant, best hybrids were P5 × P9, P7 × P10 and P3 × P9.
