“…However, our results suggest that ISSR-PCR products generated with di-nucleotide motif primers can be useful markers for analyses of French bean germplasms. Similarity value based on Jaccard's coefficient clearly demonstrates that overall similarity between genotypes was low, reflecting strong genetic differentiation among the lines tested and our results were in accordance with previous investigators (Alghamdi et al 2011;Immaculee et al 2015, Jannat et al 2022.…”

Background: Crop improvement has paramount importance to meet the global demand of food to feed the growing human population. Methods: A total of 23 French bean genotypes with diverse genetic background were taken to assess their phenotypic attributes and molecular characterization using inter simple sequence repeat (ISSR) markers. The data collected during two growing seasons over four locations on different quantitative characters were pooled and analyzed under randomized complete block design for deciphering the extent of genetic diversity. Similarity value, based on Jaccard’s coefficient and UPGMA (un-weighted pair group method with arithmetic mean) analysis was calculated. The dendrogram was constructed using Jaccard’s similarity matrix for above analysis. Result: The genotypes showed a wide variation in morphological characters like plant height, pods per plant, pod weight, pod length and pod yield per plant. The genotype HAFB-5 showed the maximum potential for pod yield per plant and long pods. Four ISSR primers used in this study amplified 27 reproducible bands with 18 (66.66%) polymorphic. The genotype Kashi Param and HAFB-4 were found diverse among the selected genotypes on the basis of molecular markers.

“…Because of the limitation of morphological and biochemical markers, efforts were being directed to use Simple Sequence Repeats (SSRs) to study the genetic diversity of common beans (Hamman et al 1995;Gopinath et al 2013;Zargar et al 2016;Jannat et al 2022). SSRs were used to study the allelic variation within a locus.…”

“…The selected parameters were found to be significant based on the F values, significance level p ≤ 0.1, and p-values less than 0.1. For instance, Sammyia et al reported highly significant results for 36 common bean genotypes' quantitative attributes [25]. Freeze-dried biomass from the accessions was analyzed by means of HPLC-MS/MS to determine various forms of phenolic acids and flavonoids.…”

This study aimed to investigate the availability of flavonoids, anthocyanins, and phenolic acids in mutant bean seeds, focusing on M7 mutant lines, and their corresponding initial and local cultivars. HPLC-DAD-MS/MS and HPLC-MS/MS were used to analyze twenty-eight genotypes of common bean. The obtained results suggest that the mutations resulted in four newly synthesized anthocyanins in the mutant bean seeds, namely, delphinidin 3-O-glucoside, cyanidin 3-O-glucoside, pelargonidin 3-O-glucoside, and petunidin 3-O-glucoside, in 20 accessions with colored seed shapes out of the total of 28. Importantly, the initial cultivar with white seeds, as well as the mutant white seeds, did not contain anthocyanins. The mutant lines were classified into groups based on their colors as novel qualitative characteristics. Five phenolic acids were further quantified: ferulic, p-coumaric, caffeic, sinapic, and traces of chlorogenic acids. Flavonoids were represented by epicatechin, quercetin, and luteolin, and their concentrations in the mutant genotypes were several-fold superior compared to those of the initial cultivar. All mutant lines exhibited higher concentrations of phenolic acids and flavonoids. These findings contribute to the understanding of the genetics and biochemistry of phenolic accumulation and anthocyanin production in common bean seeds, which is relevant to health benefits and might have implications for common bean breeding programs and food security efforts.

“…The common bean ( Phaseolus vulgaris L.) is a legume crop that is grown worldwide for direct human consumption, income generation, and soil fertility enhancement (Jannat et al., 2022; Katungi et al., 2010; Rawal & Navarro, 2019). The average per capita consumption of common bean in Africa is high, estimated at 31.4 kg/year in the main bean production areas (Katungi et al., 2010).…”

The wild sunflower, an invasive alien species, is known to affect the performance of field crops. A field experiment was conducted to estimate the effects of different levels of wild sunflower and common bean densities on common bean yield components and grain yield, as well as to quantify yield loss due to their competition at varying densities. The experiment was laid out in a randomized complete block design in a factorial arrangement with four replications. Hence, factorial combinations of three common bean densities and five wild sunflower densities were tested at two locations. At 24 plants m−2, wild sunflower had maximum dry biomass of 413.84 and 549.83 g−2 at Adamitulu and Melkassa, respectively. An increase in wild sunflower density from 0 to 24 plants m−2 resulted in a reduction of pods per plant up to 62.41% and 83.11%, respectively, at Adamitulu and Melkassa. Compared to the weed‐free plot, the highest wild sunflower density (24 plants m−2) had a 4.6‐fold reduction in seed per pod. Weed‐free plots at Adamitulu and Melkassa yielded the highest grain yields of 2.77 and 3.37 t ha−1, respectively. Common bean grain yield reduced by 88.12% and 67.64%, in Adamitulu and Melkassa, due to the highest density of wild sunflower. The rectangular hyperbolic equation fits common bean grain yields well. This study, hence, proposes that wild sunflower plants be kept at a density of no more than three plants per meter square to minimize severe yield loss and help common bean growers make decisions on wild sunflower control.
