Abstract

Faba bean is a nutritionally and medicinally rich popular legume crop. However, vicine-convicine remain as potential threats for “favism” in human beings. In this study, 189 diverse faba bean accessions have been evaluated for yield component traits and vicine content in seeds followed by a correlation study. Combined genetic variability analysis shows that traits like days to pod initiation (DPI), pod length (PL), test weight (TW) and grain yield have minimally been influenced by the environment. PCA revealed that TW, PL and PW were the primary indicators for deciding yield performance. LC–MS/MS confirms that vicine concentration varied in between 3.489 and 10.025 g/kg and a significant positive correlation (0.40***) was observed between vicine conc. and grain yield of faba bean. Thus, present study demonstrated that the faba bean genotypes containing lower vicine were mostly poor yielding, which might be regulated by vicine in faba bean. Therefore, complete elimination of vicine or development of near-zero vicine faba bean could drastically reduce the yield potential of the crop, hence one has to be very cautious and follow efficient selection strategies while optimizing lower concentration of vicine for development of low vicine varieties. This study shows that faba bean genotypes containing 4.0–5.5 g/kg vicine were fairly productive and also have considerably lower vicine.
