Performance of golden flax for genetic variability and heterosis under utera & rainfed situation

Sadhna Saha, Nandan Mehta, Amrita Giri and Sonal Upadhyay
An experiment was conducted at the Research cum Instructional Farm of AICRP on Linseed, Department of Genetics and Plant Breeding, College of Agriculture, Indira Gandhi Krishi Vishwavidyalaya, Raipur, Chhattisgarh during Rabi season 2019-20 and 2020-21 comprising forty (40) accessions including checks viz; golden flax (37) & brown flax (3) (checks RLC-143, RLC-148, RLC-153 and Surabhi). Genetic variability and heterosis estimation were done by growing these lines in two situations in randomized complete block design with three replications during rabi 2019-20 and rabi 2020-21 under utera and rainfed situation. Observations were recorded on seed yield and contributing traits (Days to 50 percent flowering, days to maturity, plant height, technical plant height, no. of capsule per plant, no. of seed per capsule, 1000 seed weight, oil content, seed yield per plant). Among all traits number of capsule, capsule size, number of seeds in capsule and seed yield per plant were observed with high GCV, PCV and high heritability with high genetic advance in both situations (ytera and rainfed) and hybrid Crosse combinations viz., YLS-17 x RLC-143, YLS-18 x RLC-143 & YLS-2 x RLC-143 were found promising to develop golden flax improved varieties as they shown vigor for yield contributing character.
