Performance and reaction of faba bean genotypes to chocolate spot disease
Abstract Background This study aimed to development new faba bean hybrids resistant to chocolate spot disease and using them in breeding programs. Six faba bean genotypes were crossed in a diallel system excluding reciprocals during three growing seasons of 2017/18, 2018/19 and 2019/20 growing seaso...

| Summary: | Abstract Background This study aimed to development new faba bean hybrids resistant to chocolate spot disease and using them in breeding programs. Six faba bean genotypes were crossed in a diallel system excluding reciprocals during three growing seasons of 2017/18, 2018/19 and 2019/20 growing seasons. Results Results scored high variability among genotypes (parents and their crosses) in most studied characters. All characters were affected by inbreeding and most crosses recorded high significant in all characters especially the positive significance of resistance to chocolate spot disease (gain) was 5 for all studied resistance characters. Conclusions All studied plant growth and yield characters were affected negatively by chocolate spot disease. Moreover, it can be concluded that the commercial cost of producing hybrid seed can be reduced by growing F 1 or directly. |
