Genetic Diversity and Field Performance of Mung Bean, Faba Bean and Lentil Genotypes in the Kingdom of Saudi Arabia

Abstract

Grain legumes are grown for their high proteins and biological nitrogen fixation ability. In this study, 3 mung bean, 4 lentil and 20 faba bean genotypes from the Kingdom of the Saudi Arabia were evaluated for genetic diversity. There were significant differences in the morphological and molecular characteristics in the tested mung bean (Vigna radiata L.), lentil (Lens culinaris Medik.) and faba bean (Vicia faba L.) genotypes. The sequence-related amplified polymorphism (SRAP) and amplified fragments length polymorphism (AFLP) markers exhibited a considerable genetic diversity among the tested genotypes of all three legume crops. The genotypes differed for plant height, primary branches, pod length, pods per plant, grain per pod and 100-grain weight. All the tested genotypes of mung bean, lentil and faba bean differed in the number of alleles. Maximum number of alleles per primer combination was 112 in mung bean, 72 in lentil and 126 in faba bean.Polymorphism percentage of all the tested genotypes of the mung bean and lentil was 100% and in faba bean, it ranged from 97 to 100%. Existence of genetic diversity of these tested mung bean, lentil and faba bean genotypes offers opportunities to exploit favourable alleles for use in the breeding program aimed at yield improvement.

Evaluación fenotípica de semillas de haba (Vicia faba L.) colectadas en Nariño-Colombia

“…Las primeras variables refieren semillas maduras, con valores promedio en LP, desde 2,28 a 3,05 cm y en LE, desde 1,78 a 2,28 cm. La estimación de la LP superior a 2,0 cm permitió clasificar la totalidad de la colección de V. faba dentro de la subespecie botánica major, cultivada para consumo humano, a nivel mundial, que se diferencia de las subespecies minor y equina, por el tamaño de la semilla (Alghamdi et al 2017;Alharbi & Adhikari, 2020).…”

“…Basados en la tasa de polinización cruzada natural del haba, que oscila entre 10 y 70 %, se debe considerar el flujo genético como un factor de variabilidad en el genotipo y el fenotipo (Duc et al 2015;Alghamdi et al 2017), lo que indica que, bajo situaciones de polinización cruzada, el color de las semillas podría cambiar de una generación a otra. Al respecto, Rebaa et al (2017) encontraron, en estudios realizados en Tunes, elevado flujo de genes entre localidades geográficas, debido a la acción de los insectos polinizadores, como abejorros y una gran diversidad de abejas solitarias, de los géneros Anthopora y Xylocarpa.…”

Genetic relationship of mungbean and blackgram genotypes based on agronomic and photosynthetic performance and SRAP markers

“…A set of 25 SRAP primer combinations revealed a high polymorphism percentage of 90.2% (representing the profiles of 507 polymorphic bands from 562 scorable bands with a size range of approximately 200 to 1,400 bp as shown in Table 3). However, Aneja et al (2013) and Alghamdi et al (2017) found 100% polymorphism among Indian mungbean varieties and Saudi mungbean germplasms, respectively. Although we obtained a comparatively lower polymorphism percentage than those of previous studies, our study used higher numbers of primer combinations and scorable DNA bands, both of which may affect polymorphism percentage.…”

“…Because of its simplicity, high reproducibility and because no prior genome sequence is needed, this method has become attractive for breeding programs. Aneja et al (2013) and Alghamdi et al (2017) found that all SRAP primer combinations exhibited 100% polymorphism, thereby being useful in genetic assessment amongst mungbean accessions, as well as other Vigna spp. The objectives of this study were: i) to evaluate agronomic and photosynthetic performance of 23 mungbean and four blackgram genotypes and ii) to estimate their genetic diversity and relationships using SRAP markers.…”

Agronomic behavior of broad bean genotypes for the Colombian high andean zone

“…The inclusion of rotation systems improves soil fertility by symbiosis with Rhizobium sp. that allow the fixation of atmospheric nitrogen, and the incorporation of crop residues increases organic matter (Alghamdi et al, 2017;Horque, 2004).…”
