Abstract:

M3 generation of thirty four mutant lines was developed from genotype Girge local which was irradiated with 500 Gydose of gamma rays which was studied along with three checks viz., Dapoli-1, Dapoli-2 and Dapolisafed for estimation of genetic parameters. The genetic parameters viz., Components of variances, coefficient of variations, heritability, genetic advance and genetic advance as per cent of mean were estimated for quantitative and qualitative traits. Significant differences among the entries were studied for all the traits.The estimated data on genetic parameters revealed that genotypic and phenotypic variances were highest for calcium content followed by grain density, indicating highest wide variability for this character. The traits viz., iron content, number of productive tillers, calcium content, straw yield plant -1,number of fingers plant-1, and main earhead length were recorded with high GCV and PCV. Higher heritability was observed in the traits viz., iron content, calcium content, protein content, number of productive tillers plant-1, main earhead length, main earhead length and number of fingers plant-1. The high genetic advance was estimated for the character, calcium content (92.46 mg/100g) and grain density (11.95). Only calcium content showed high heritability accompanied with high genetic advance among all the studied traits indicates that, most likely their heritability is due to additive gene effects and selection is effective for this trait. The mutant lines viz., 18 NMS-12 and 18 NMS-34 were found early flowering and early maturing among the studied mutant lines. Regarding to quality parameters high iron content was observed in mutant lines 18 NMS-24 (23.72 mg/100g) and 18 NMS –18 (22.28 mg/100g). The mutant lines viz., 18 NMS-21 (11.05%) and 18 NMS-15 (10.56%) recorded higher protein content. While the lines 18 NMS-10 (360 mg/100g) and 18 NMS-20 (354 mg/100g) recorded higher calcium content. The mutant lines viz., 18 NMS-31 and 18 NMS-23 were recorded significantly higher values for yield and yield contributing traits viz., grain yield plant-1, weight of earhead plant-1, number of fingers plant-1, main earhead length, grain density and number of productive tillers plant-1. Which may be exploited for commercial purpose after multilocation testing along with suitable check if found promising.
