Abstract

Two field experiments were done during 2019/2020 and 2020/2021 seasons at the Agricultural Research of Faculty of Agriculture, Zagazig University, El-Khattara region, Sharkia Governorate, Egypt, using nine faba bean genotypes to estimate genetic variability, correlation as well as factor analysis of yield and yield component characters. The results revealed significant differences among faba bean genotypes for all the studied characters. Genotypes Giza 716, Sakha 4, L 33, L79, L 86 and Giza 843 performed well for yield and its component characters. Maximum phenotypic variance (Vph) and genotypic one (Vg) values were recorded for number of branches/plant and 100 seed weight. The phenotypic coefficient of variation (PCV) and genotypic coefficient of variation (GCV) ranged from 38.03 for number of branches/plant to 145.75% for number of pods/plant and from 26.16 for number of seeds/ pod to 142.72 %for number of pods/plant, respectively. The highest heritability estimates were detected for number of pods/plant, number of seeds/pod, number of branches/ plant and plant height. The factor analysis technique divided the studied variables into two main factors. These two factors accounted about 77.012% of the total variability in the dependence structure of faba bean seed yield. The first factor included three variables and accounted 55.705%, whereas, the second one consists of two variables and accounted 21.107% of the total variability of faba bean seed yield.
