Abstract

A field experiment was conducted during rabi 2022-23, to study the drought tolerance in different genotypes of linseed under rainfed and irrigated condition genotypes NL 367, NL 371, NL 407, NL 408, RL 18114, BAU 2021-06, T 397, JLS 95 (C), LSL -93 (C), PKV NL- 260 (LC) were studied. The experiment was laid down in Randomized Block Design with ten genotypes and three replications at research farm of AICRP on Linseed and Mustard, College of Agriculture, Nagpur. It is important to screen and identify the drought tolerant and widely adoptable genotypes in respect to yield and yield contributing traits, which could perform uniformly under different environmental condition. The aim of this work was to study the drought tolerant associated morpho-physiological traits and yield of linseed under rainfed and irrigated condition. Observations about morpho-physiological parameters like plant height, number of branches plant-1, number of capsule plant-1, relative water content, root volume, root length and chlorophyll content (SPAD) were also estimated. Observations on yield traits like grain yield plot-1 ha-1. Seven genotypes of linseed with three checks were evaluated in Randomised Block Design for 13 morphological characters under two environments, irrigated and rainfed during rabi 2022-23. Significant differences were observed among the genotypes for all the characters studied under both the conditions. Recorded Genotypes PKV NL 260 followed by LSL 93 (C) NL 367 and NL 408 were significantly enhanced morpho-physiological traits and yield of linseed under rainfed condition, when compared with national check T-397 and rest of the genotypes under study.

Conclusion

The genotypes of linseed in rainfed moisture stress condition showed significant variation in morpho-physiological parameters were recorded significantly higher values in PKV NL 260 followed by LSL 93 (C), NL 367 and NL 408 which are to be drought tolerant genotypes. None of the genotypes showed significant increment in yield attributing characters under rainfed moisture stress condition over best PKV NL 260 local check genotype. PKV NL 260 followed by LSL 93 (C), NL 367 and NL 408 recorded significantly highest values for yield and yield attributing traits, viz., Yield and yield attributing characters (number of capsules plant-1, test weight, seed yield plant-1 and seed yield plot-1), which are said to be drought tolerant genotypes. The genotype of linseed under rainfed moisture stress condition study, local check PKV NL-260 (LC) was significantly superior due to enhanced all morpho- physiological, chemical and biochemical and yield contributing characters.
