Abstract:
The research was conducted at Homimah during tow cropping seasons 2019/2020 and 2020/2021. in order to estimate hybrid vigor and heritability for 18 hybrid groups of faba beans obtained by hybridization method line × tester. In the first season parents (baladi mohasan, hama2, haha3) as female and (G8, G9, G23, G24, G36, G69) as male were planted and at flowering stage lines x testers cross were done and Eighteen Hybrids group were obtained. In the second season Hybrid groups and their parents were planted in Randomized complete block design with tow replications Analysis of variance, Hybrid vigor and heritability for plant Hight, bod length, flowing days, maturity days were assessed. Analysis of variance showed genotypic variance was less than environment variance for plant height and bod length whereas more than environmental variance and heritability for flowering days and maturity days. Hybrid groups (Hama3 x G8), (Hama3 x G23), (Hama2 x G69) and (baladi mohasan x G69) have had high negative significant of mid parent hetero vigor for flowring days numbers and maturity days numbers (-2,,-2) , (-1,-2), (-1,-2), (-2,-2) as all in positive direction , whereas hybrid group (Hama x G69) have had significant best parent hetero vigor (1) for flowering days and (-46) for pod length and they negative directions.
Keywords: Faba bean, lines x testers, Heterosis, heritability.
