GAMMA RAYS INDUCED HIGH YIELDING KABULI TYPE CHICKPEA MUTANT VARIETY
Abstract
Pure seeds of a kabli type chickpea exotic variety ILC-195 were irradiated at 0.45 kGy dose of gamma radiation in 1990 and the mutant line CMNK-287-3 was selected in Mr generation on the basis of high yield, discase resistanoe and plant type. After confirmation of its resistance to blight and wilt in Me and Ms the mutant line CMNK-287-3 alongwith other promising kabul type chickpea mutants/varieties was evaluated in various yield trials and at different locations. The mutant line CMINK-287-3 was tested in advanced yield trial consecutively for two years, 1998-99 and 1999-2000 and yielded 2753 and 2554 kg/ha, respectively, as compared to the check varieties Noor-91(2200 kg/ha) and Pb-I(1022 kg/ha), respectively. The mutant line also proved superior in zonal yield trial, 1999-2000 by giving mean yield of 1496 kg/ha. The mutant line CMNk-287-3 has significantly higher protein content (23.89%) as compared to the parental variety IC-195(19.8%), The Provincial Seed Council approved the mutant line CMNK-287-3 by the name "Hassan-2K" for general cultivation in NWFP.
