Stability analysis over environments in linseed (Linum usitatissimum L.) varieties

Abstract

A field experiment was conducted during Rabi season of 2015-16. To study the stability analysis of yield and its component traits in 20 genotypes of linseed i.e.; NPHY-29, NP-121, NPRR-271, NPRR-402, RL-28-1, AHUDERA-170, NPHY-39, NPRR-28, NPHY-38, POLF-6, LCK-87312, RR-76, No-356, No-8, L-53, SJKO-05, No-3, 141No18 X RR-9, LMHS-397 and SJKO-55 will be grown in randomized block design with three replications at three different locations (Kanpur, Mainpuri and Mauranipur). The observations were recorded on some biological characters, viz.; 1000-seed weight (g), seed yield per plant (g), oil content (%), protein content (%), palmitic acid, stearic acid, oleic acid, linoleic acid and linolenic acid. In the present study of material SJKO-05 for 1000-seed weight (g), seed yield per plant (g) and protein content (%) were found to be stable because b1 was near to unity, S2 di was not significant and mean values were more than population mean which was desirable. NP121 and NPRR 271 for palmitic acid, stearic acid, oleic acid and linolenic acid were found to be stable because b1 was near to unity, S2 di was not significant and mean values were less than population mean which was desirable.
