“…The variation in harvest duration could be due to genotypes, environmental conditions, or interaction of both. The findings of this research showed the longest harvest duration (29 days) in Four Season which contradicts the findings of Dhakal et al, (2020) who reported the longest harvest duration in Semi Light Long such variation might be due to the difference in the growing season.…”

“…The differences in pod length and pod diameter among the genotypes might be due to differences in their genetic makeup. Dhakal et al, (2020); Pandey et al, (2011) also reported similar variations in pod length and pod diameter of different genotypes. Highly significant variation among varieties of bean for single pod weight was reported earlier by Kalauni et al (2019) and Muthal et al, (2018).…”

“…During both years Rust incidence was observed more in Semi Light Long (3.00) followed by Trishuli (2.33) whereas the least intensity was observed in Long Green Bean (1.16). However, Dhakal et al (2020) reported high rust intensity in Long Green Bean and less rust intensity in Four Season; such variation might be due to different growing conditions. Similarly, two years' results against scoring of Yellow Bean Mosaic Virus |(YBMV) showed significant variation among tested genotypes (Table 7).…”

“…However, it has some disadvantages such as small pod size, low yield, and short harvest duration. It has also been cultivated in farmer's fields for a long time but has yet to be registered to the National Seed Board (Dhakal et al, 2020). Farmers have very little varietal option for spring season planting therefore; the current research was conducted to identify suitable bean genotypes for spring season planting under mid hills of Nepal.…”

An experiment was conducted at National Horticulture Research Centre (NHRC), Khumaltar, Lalitpur, Nepal from March to July of 2019 and 2020 to identify suitable bean genotypes for spring season planting. The experiment was laid out in Randomized Complete Block Design (RCBD) with three replications having seven genotypes as treatments viz. Semi Light Long, Long Green Bean, Trishuli, Four Season, LB-37, Pahelo Gheusimi, and Khairo Gheusimi. Observations were recorded on morphological characters, yield, and yield contributing attributes. All genotypes under study showed significant differences among each other. Pahelo Gheusimi was found to be early maturing (81 days after sowing) whereas genotype Four Season had the longest harvesting duration (29 days). Similarly, pod length (20.52 cm) and pod weight (16.60 g) was recorded highest in Long Green Bean, while the highest pod diameter was recorded in Pahelo Gheusimi (12.59 mm). A significantly highest number of pods (92/plant) was observed in Four Season whereas the highest fresh pod yield (1030.3 g/plant) per plant was observed in Long Green Bean which was at par with Four Season (997.1 g/plant). The calculated yield per hectare was 2.5 times higher in Long Green Bean (28.66 t/ha) as compared to the national average in 2020. Both rust incidence and Yellow Bean Mosaic Virus susceptibility were found less in Long Green Bean and Four Season. Based on the two-year observations, Long Green Bean and Four Season were found to be promising for spring season planting.

The experiment was conducted at the end of July in NHRC, Khumaltar (1332 masl) located at Longitude 27.6485o N and Latitude 85.3253o E situated at Province no. 3, Lalitpur, Nepal in 2077/04/18 to 2077/04/28. The experiment was carried out in Randomised Complete Block Design (RCBD) with four treatments and five replications. The genotypes Trishuli, Chaumase, Semi Light Long and Semi Long Green Bean were used as treatment. Phenotypic traits like Plant Height, Days to maturity, Number of node at harvest in main stem, Flower colour, No of pod per plant at harvest, Dry pod colour, Single pod weight at harvest, pod length, Seed yield per plant, Seed weight per pod, 1000 seed weight, Moisture %, Seed weight per plant(gm), seed weight per pod after drying per plant (gm), seed weight after drying were taken. Plant height was highest in Semi long ligh which is 332 cmt and lowest in Trishuli which is 294.48 cm. Total number of seed was found highest in Semi Long Green 8.6 and least in Trishuli 7. The highest yield was found in Trishuli 2.69 ton/ha followed by Chaumase 2.56 ton/ha, Semi long green 2.33 ton/ha, and the lowest was seen in Semi Long Light 1.51 ton/ha.

Adzuki beans are widely cultivated in East Asia and are one of the earliest domesticated crops. In order to gain a deeper understanding of the genetic diversity and domestication history of adzuki beans, we conducted Genotyping by Sequencing (GBS) analysis on 366 landraces originating from Korea, China, and Japan, resulting in 6586 single-nucleotide polymorphisms (SNPs). Population structure analysis divided these 366 landraces into three subpopulations. These three subpopulations exhibited distinctive distributions, suggesting that they underwent extended domestication processes in their respective regions of origin. Phenotypic variance analysis of the three subpopulations indicated that the Korean-domesticated subpopulation exhibited significantly higher 100-seed weights, the Japanese-domesticated subpopulation showed significantly higher numbers of grains per pod, and the Chinese-domesticated subpopulation displayed significantly higher numbers of pods per plant. We speculate that these differences in yield-related traits may be attributed to varying emphases placed by early breeders in these regions on the selection of traits related to yield. A large number of genes related to biotic/abiotic stress resistance and defense were found in most quantitative trait locus (QTL) for yield-related traits using genome-wide association studies (GWAS). Genomic sliding window analysis of Tajima’s D and a genetic differentiation coefficient (Fst) revealed distinct domestication selection signatures and genotype variations on these QTLs within each subpopulation. These findings indicate that each subpopulation would have been subjected to varied biotic/abiotic stress events in different origins, of which these stress events have caused balancing selection differences in the QTL of each subpopulation. In these balancing selections, plants tend to select genotypes with strong resistance under biotic/abiotic stress, but reduce the frequency of high-yield genotypes to varying degrees. These biotic/abiotic stressors impact crop yield and may even lead to selection purging, resulting in the loss of several high-yielding genotypes among landraces. However, this also fuels the flow of crop germplasms. Overall, balancing selection appears to have a more significant impact on the three yield-related traits compared to breeder-driven domestication selection. These findings are crucial for understanding the impact of domestication selection history on landraces and yield-related traits, aiding in the improvement of adzuki bean varieties.
