Tolerance to post-emergence herbicide Imazethapyr in chickpea

摘要: The present research work aimed at identification of sources tolerance to herbicide Imazethapyr for their possible utilization in development tolerant chickpea. Sixty five genotypes (55 desi and 10 kabuli) screened included accessions from ICRISAT core collection, advanced breeding lines cultivars. score ranged 1.9 5.0. Nine moderately three susceptible were further evaluated under control sprayed condition. Genotype x environment interactions observed days 50% flowering, NDVI, maturity, seed yield, biomass, harvest index, 100-seed weight branched chain amino acids (BCAA) viz., valine, leucine isoleucine content. Highly significant reduction yield was all the except ICCV 10, ICCL 82104 ICC 1710 as revealed by pairwise comparison means using Tukey's test. spraying reduced total biomass production. Analysis BCAA content sample non-significant differences percent valine ICCIL 04001, 00305, 96003 82104, except, 3 case 03407, 96003, 1710, 00108 82104. post-emergence identified based on attributes 00305 1710. These can be used study genetics chickpea programs developing with Imazethapyr.
