Genetic diversity for agro-morphological characters and nutritional compositions of some local faba bean (Vicia faba L.) genotypes

Abstract

This study was carried out in Mediterranean climate and under rainfed conditions in Turkey for a period of three years throughout the growing seasons of 2014/2015, 2015/2016 and 2016/2017. It was conducted in a randomized complete block experimental design (RCBD) with three replications. In present study, genetic diversity for agro-morphological characters and macro/ microelements were investigated in sixteen promising local faba bean genotypes originated from Turkey. According to the results of the study, mean grain yield varied from 2320 kg ha -1 (Tekirdağ-39) to 3130 kg ha -1 (Burdur-50). 100-grain weight and branches per plant had high heritability and genetic advance as a percentage of mean. As for path analysis; plant height, branches per plant and 100-grain weight had a major role in improving the grain yield of faba bean. Therefore, effective selection for mentioned traits can be made for increasing grain yield in faba bean. Wide diversity for macro and micronutrients in the studied local genotypes can be considered for improving new faba bean cultivars in Mediterranean climate conditions as well.

Steps toward developing legume cover crop varieties: Study of biomass and nitrogen partitioning and within‐plant δ115N variation of faba bean at different growth stages

“…The genotypes used in this experiment belonged to the large, medium, and small-seeded faba bean categories with 100KWT of about 160 g (Windsor), 105 g (PI 678631), and 27 g (PI 655333) (https://www.favabeanresearch.com/ germplasm). Although positive correlations between faba bean seed size and agronomic traits, including plant DM, N, and grain yield, have been previously reported (Maalouf et al, 2019;Ton et al, 2021), this study found greater total DM and N for the medium-seeded PI 678631 than the large-seeded Windsor. While this result from the present study may be due to the small number of faba bean lines tested, the correlation coefficient for seed size with 100 KWt and N yield (total plant N) in the study of Boots-Haupt et al (2022) was 0.57 and 0.51, respectively.…”

Exploration of global faba bean germplasm for agronomic and nitrogen fixation traits

“…In addition to cover cropping, recent breeding efforts have focused on the development of faba bean plant materials for grain and vegetable production (De Cillis et al., 2019; Khazaei et al., 2021). However, successful plant materials within the cover crop, dry grain, and vegetable market classes of faba bean greatly differ in terms of seed size, compositional quality, maturation, and plant height and therefore require targeted breeding efforts (Etemadi et al., 2018; Ton et al., 2021). Many of the aforementioned traits are highly heritable and therefore place greater emphasis on selection of a suitable cultivar than leveraging on‐farm management practices (e.g., amount of fertilizer applied) (Duc et al., 2010).…”

“…Many of the aforementioned traits are highly heritable and therefore place greater emphasis on selection of a suitable cultivar than leveraging on‐farm management practices (e.g., amount of fertilizer applied) (Duc et al., 2010). Greater opportunities to develop locally adapted plant materials continues to become more feasible with the development of faba bean breeding tools such as speed breeding (Mobini et al., 2020), germplasm (Neda et al., 2021; Ton et al., 2021), and genomic resources (Carrillo‐Perdomo et al., 2020)—cultivating opportunities to nourish regional communities and support sustainable agriculture.…”
