“…Minimum (SYP -1 ) was recorded in Line-1 having value of (25.77 g) followed by Line-10 (34.83 g) and Line-4 (45.02 g) ( Table 3). Mean value of the trait was found to be 54.89 g. Similar results were also obtained by [30]. However there is difference between the genotype mean square values and coefficient of variation of the current study and previous analysis which might be due to environmental factors, polygenic nature of the trait and difference in experimental area.…”

The present research study was aimed for estimation of genetic diversity and characterization of various morphological and biochemical traits of kidney beans (Phaseolus vulgaris L.) with the objectives of identifying superior genotypes at the Research Farm, The University of Haripur during zaid-rabi season 2018.Twelve different kidney bean genotypes were evaluated by using Randomize Complete Block Design (RCBD) with three replications. Data was recorded for various morphological and biochemical traits. Analysis of variancerevealed highly significant genetic diversity.Minimum days to emergence were recorded for Line-12 (22.66 days), having moderate plant height of (89.44 cm), longer pods (13.003 cm) containing maximum number of seeds (6.55). Minimum days to flowering were observed for Line-1 (59 days). Maximum plant height was recorded for Line-5 (99.11 cm). Maximum numbers of pods were produced by Line-9 having (16.28). Maximum pod length (13.55 cm) was observed for Line-2. Seeds per plant were maximum in Line-9 (72.97). Line 4 produced larger size bean seeds having maximum 100 seed weight (55.74 g). Total phenolic compounds were observed to be maximum in Line-10 (88.24 mg/100g) while total antioxidants were maximum in Line-7 (136.88). Based on the characterization of kidney bean genotypes at Haripur, the genotypes viz. Line-9 and Line-12 were observed superior having minimum days to emergence, moderate plant height, early maturity, high yield. Therefore, these genotypes are recommended for further characterization in the kidney bean breeding programfor further evaluation.

“…The frequency of green pod color was high in indigenous landraces as well as in Mesoamerican group. A similar variation in pod color was also reported by Chhetri and Bhatta (2017). Rana et al (2015) also described that green pod color was predominant with various intensities of dull to shiny green in majority of accessions studied by them.…”

“…Similarly, Fisseha et al (2018) also observed white and purple flower color in common beans landraces of Ethiopia. Contrarily to our results, Chhetri and Bhatta (2017) reported a wider range of flower colors in their study while Rana et al (2015) observed white, pink and lilac flower colors among 4274 accessions with predominance of white color. Pod color ranged from light green to green as well as purple shade on green, purple strips on green and red strips on green color in the current investigation.…”

C ommon bean (Phaseolus vulgaris L.) is an annual, predominantly self-pollinated leguminous crop grown worldwide in a broad range of environments and cropping systems (Fetahu et al., 2014). The rate of outcrossing in common bean is below 5% (Gepts et al., 2008). It is morphologically diverse crop with distinguishable qualitative and variable quantitative traits ( Joshi et al., 2009). Generally, genetic variation in bean's landraces is considerably high and has the most diverse population of cultivated crops (Frankel et al., 1995;Qualset et al., 1997). Qualitative traits are deemed useful for assessment of genetic diversity and its relationship in different crop species. High morphological diversity among genotypes is helpful in recombination of genotypes for important economic qualitative and quantitative traits (Balkaya et al., 2005). Therefore, due to high genetic diversity, the landraces are considered as a valuable source of Abstract | Common beans (Phaseolus vulgaris L.) being dual purpose (vegetable plus legume) is grown worldwide and in Pakistan specifically in the Himalayan range. Local landraces cultivated in traditional farming systems are the sole source of its production. 108 land races of beans including 96 landraces of Himalayan region, the ten Mesoamerican and the two Andean genotypes were evaluated at three locations during 2015 and 2016 at the Summer Agricultural Research Station Kaghan, Batakundi Potato Seed Farm Batakundi and Agricultural Research Station Baffa, Mansehra. This two year study is pioneer in Pakistan with an objective to document the characteristics of common bean landraces originating from the three different regions (Himalayan, Mesoamerican and Andean). Furthermore, diversity in qualitative traits (leaf color, leaf pubescence, hypocotyls pigmentation, flower color, pod color, growth habit, dry pod color, pod curvature, pod beak position, pod beak orientation, seed shape, seed coat pattern and seed color) was studied by using standard Chi square test for homogeneity of populations. Results showed that agro climatic conditions have no influence on the qualitative traits. Secondly, each landrace has its own specific and distinguishing trait like flower color, growth habit. Moreover, the traits were found highly heritable and genetically controlled as no environmental influence was observed based on two years data. Therefore, these traits can be considered to identify and distinguish landraces from each other, may be used as morphological markers in maintaining germplasm purity.

“…Indeed, black bean soup is given to their sick people as an energy supplement. Farmers in Nepal preferred bean landraces that are medium growth habit, early maturing nature, high yielding, good seed size and color and are high demand in the market [5,12]. A similar study was done in bean growing area in Malawi to understand the farmer's specifications for variety selection showed that farmers looked on grain color, cooking time, taste, grain size as well as grain brightness to choose the varieties [13].…”

Rajma (Phaseolus vulgaris L) known as the common bean, French bean, kidney bean, bush bean, and pole bean is the most important grain legume of Nepal which covers about 10,529 ha areas along with the productivity of 1477kgha-1. Generally it is grown during summer in mid/high hills and during winter (post rainy) season interai/inner terai in rice and maize based eco-system. Now Rajma bean is being popular as the cash crop in the province 3, 5 and 6 because of producing organic products and tastier quality. Multi-environment trials was carried out at Nepalgunj, Parwanipur, Itahari and Surkhet during the winter season of 2014-2017 comprised of 10 diverse Rajma genotypes in Randomized Complete Block Design with three replications in order to evaluate the quantitative variation with respect to yield and yield contributing traits. The combined analysis of variance showed that the highly significant differences among the genotypes and locations in the traits like days to flowering, days to maturity, plant height, hundred seed weight and grain yield. However; there was not any GxE interaction effect found in days to flowering, days to maturity and grain yield. Mean yield performances showed that the genotype PDR-14 (2341kgha-1) produced the highest yield followed by Utkarsh (2332kgha-1) and Arun-2 (2021kgha-1). In conclusion, PDR-14 gave 9-56% higher yield among the genotypes and its stability analysis test also indicated that PDR-14 was found a highly stable across the environments and over the years. Variegated red kidney shape seed, white flowers along with dwarf and glabrous leaf pubescence is the DUS trait of the PDR-14 and recommended for terai/inner terai to high hills.
