| dc.description | Induction and evaluation of polygenic variability following treatments with gamma rays, EMS and their combinations were studied in chickpea var. Pusa-372. Mean values for various quantitative traits increased at lower or intermediate treatments and decreased at higher treatments in M2 generation. For days to flowering, days to maturity and plant height, mean values significantly decreased, whereas, for yield and yield contributing traits, mean values increased significantly in M3 generation. A considerable amount of variability was induced in the treated populations in M2 generation. Heritability and genetic advance values were quite high in M2 as compared to control for all polygenic traits which increased further in M3 for all yield contributing traits. Increase in the mean values of various polygenic traits, especially yield contributing traits, coupled with increase in heritability and genetic advance suggest fixation of desirable alleles for these traits and scope for selection of desirable high yielding types in chickpea. | en-US |

Variabilidade poligênica induzida para característicasquantitativas em grão de bico var. Pusa-372ResumoIndução e avaliação da variabilidade poligênicas seguindo tratamentos com raios gama, EMS esuas combinações foram estudadas em grão de bico var. Pusa-372. Os valores médios para váriascaracterísticas quantitativas aumentaram a tratamentos mais baixos ou intermediários e diminuírama tratamentos mais elevados na geração M2. Para dias para florescimento, dias para maturação ealtura da planta, os valores médios diminuíram significativamente, enquanto que, para a produçãoe as características que contribuem para seu rendimento, os valores médios aumentaram deforma significativa na geração M3. Uma quantidade considerável de variabilidade foi induzidaem populações tratadas na geração M2. Os valores de herdabilidade e avanço genético forambastante elevados em M2 se comparados ao grupo controle de todos os traços poligênicos, queaumentaram ainda mais no M3 para todas as características de rendimento de contribuição. Oaumento nos valores médios de vários traços poligênicos, especialmente traços que contribuempara o rendimento, juntamente com o aumento da herdabilidade e o avanço genético, sugeremfixação de alelos desejáveis para essas características e possibilidades de seleção de tipos de altorendimento desejável para o grão de bico. | pt-BR |
