Identifying hereditary potential of lentil (Lens culinaris L.) genotypes against tolerance to various post-emergent weedicides

Abstract

Weed management is an essential agronomic practice to maintain yield in important crop like lentil. There is not any suitable herbicide encouraged in lentil to manage this problem because of its sensitivity. 55 different lentil genotypes were put under test to identify different weedicide tolerant genotypes. Significant differences among genotypes were observed in response to Flumetsulam, Carfentrazone and Oxyflurofen tolerance and categorized as tolerant, moderately tolerant, sensitive and highly sensitive on the basis of visual scoring. Among these a small set of 10 genotypes including tolerant and moderately tolerant were also assessed to identify the effect of herbicides on morpho-physiological parameters and yield attributes. Deleterious effect of herbicide on plant height, pods/plant, branches/plant, chlorophyll content, first pod height and yield were observed. Among all genotypes PLL-18507 and PLL-18509 demonstrated maximum tolerance and minimum yield loss against oxyflurofen treated plots.
