Yield and quality attributes of faba bean inbred lines grown under marginal environmental conditions of Sudan

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.

The GT biplot analysis of green bean traits

“…Therefore, 100SW, NSPl and NPP showed positive correlation with GY, PY and SWP. These results corroborate studies that assessed the correlation between these agronomic variables in different bean genotypes (GASIM et al, 2015;GONÇALVES et al, 2017).…”

Photosynthetic and physiological responses of small seeded faba bean genotypes (Vicia faba L.) to salinity stress: identification of a contrasting pair towards salinity

“…The national average of productivity is about 42% below the worldwide reduce the harmful effect of salinity on crop production, it is important to cultivate tolerant genotypes. Recently, conventional selection and breeding techniques were used in the study of crop salinity tolerance (Gasim et al 2015, Mahlooji et al 2018. Nevertheless, the insufficient understanding salinity tolerance and the absence of an adequate method of screening techniques limit the effort of breeding for salinity tolerance (Munns and James 2003).…”

Impact of Bee Pollination on Yield of Faba Bean (<i>Vicia faba</i> L.) Grown under Semi-Arid Conditions

“…Faba bean (Vicia faba L.) is a globally important grain legume crop due to its How to cite this paper: Gasim beneficial role in sustainable cropping [1] and rising requirements for plant protein as food and feed [2]. In Sudan, due to the recent increase in animal protein price, most of people shift towards less reliance on meat to supply their daily dietary protein from plant protein, especially faba bean [3], a situation that necessitates an increase in crop yield [4] [5]. Different from self-pollinated legumes, faba bean productivity is hindered by its reproductive mode [6] as the crop is partly self-and partly cross-pollinated species (mix-mating).…”
