Abstract

Faba beans ( Vicia faba L.) represent an essential source of food protein for many people in Sudan, especially those who cannot afford to buy animal meat. The demand for faba bean seeds is greatly increased in recent years, and consequently its production area was extended southward where the climate is marginally suitable. Therefore, this study was aimed to evaluate seed yield and nutritional quality of five faba bean inbred lines grown under marginal environmental conditions of Sudan. The inbred lines have considerable ( P ≤ 0.05) variability in yield and yield components, and seed chemical composition. The mean carbohydrate content was very high (501.1 g kg⁻¹) and negatively correlated with seed yield, whereas the average protein content was relatively high (253.1 g kg⁻¹) and positively correlated with seed yield. Globulin was the significant fraction (613.5 g kg⁻¹protein) followed by albumin (200.2 g kg⁻¹protein). Biplot analysis indicates that inbred lines Hudeiba/93‐S5 and Ed‐damar‐S5 outscore other lines in terms of seed yield and nutritional quality. This study demonstrates that Hudeiba/93‐S5 and Ed‐damar‐S5 are useful candidates in faba bean breeding program to terminate the protein deficiency malnutrition and provide healthy and nutritious meal for people living in subtropical areas.

In this study, we evaluated the seed yield and quality of newly developed faba beans lines grown at marginal environment. The inbred lines showed significant variability in seed yield and quality. Inbred lines with excellent seed quality under hot environment were nominated.
