“…Lowest pod diameter of 0.79 cm was registered by Kashi Unnati and more than 20 genotypes produced at par breadth measuring pods, which were at par. Similar reports are presented by Buleti et al, 2020. Kashi Unnati produced on an average of 19.50 gram weight green pods, which was highest among all the genotypes included in the study. As many as eight genotypes produced green pods with their pod weight ranging from 2020 reported that days to maturity, pod size and pods per plant revealed significant differences among the cowpeas.…”

Background: Cowpea is a multiple-purpose, drought-tolerant, climate-smart and leguminous pulse crop. Recent studies established this crop as a potential vegetable crop with nitrogen fixation ability and round the year cultivation unlike French bean. In several crops, exotic collections imported into India have positive impact in release of new varieties. Per se performance evaluation is the best option for identification of high yielding varieties. Genetic parameters controlling the expression of yield and its components are essential in determining the effect of such genetic parameters and association among the characters enhancing the green pod yield of vegetable cowpea. Methods: A set of eighty seven genotypes of vegetable cowpea including 59 exotic collections imported from International Institute of Tropical Agriculture (IITA), Nigeria; 24 indigenous germplasm collected from different parts of India and four released commercial varieties were evaluated in a randomized block design during Kharif, 2019. The analysis of variance by Panse and Sukhatme (1985), genetic parameters by Burton and De Vane (1953) and heritability in a broad sense and genetic advance by methods given by Allard (1960) and Johnson et al. (1955) were carried out to validate the results. Result: The analysis of variance revealed that genotypes exhibited significant differences for all the characters. Based on per se performances, the exotic collections for flowering and maturity traits and check varieties followed by indigenous collections for yield and yield characters have exhibited superior performance. The highest range of variation was observed for green pod yield per plant. The highest variation was observed for pod yield per plant and number of pods per plant. The higher estimates of GCV and PCV ( greater than 20%) were registered by pod width, mature pod weight, number of pods per plant and pod yield per plant, which indicates partly the interaction of the genotypes with the environment influencing the expression of these characters. High heritability along with high genetic advance was observed for green pod yield per plant, pod length, pod width and number of pods per plant indicating that these traits were mainly governed by additive gene action and responsive for their further improvement. The maximum coefficient of variation was recorded for pod width followed by green pod yield per plant, pod weight and pod length. Green pod yield per plant has a positive and significant correlation with pod length, pod width, mature pod weight, number of pods per plant and number of seeds per pod. Hence, these characters should be considered, while selecting the genotypes for their further genetic improvement in vegetable cowpea.

“…Due to the extreme variability in leaf shape, different varieties of cowpea can be classified and distinguished based on this trait (Buleti et al, 2020). The trifoliate leaf of cowpea contains two asymmetrical lateral leaflets and one symmetrical (central) terminal leaflet.…”

Cowpea leaf width correlates with above ground biomass across diverse environments

Cowpea (Vigna unguiculata [L.] Walp.) yields within the dry savannahs of Sub-Saharan Africa are low. Given the contribution of cowpea to food security in this region, it is essential that high-yielding varieties are developed to improve crop productivity in a sustainable manner. Identifying morphological or physiological traits that correlate with biomass could assist breeders with rapid screening of diverse germplasm. This study investigated 23 diverse Nigerian cowpea lines in an environmentally controlled greenhouse and 50 diverse lines from a Multiparent Advanced Generation Intercross (MAGIC) population in the field to identify easily measurable traits associated with high above ground biomass. Correlation analyses found that leaf traits were significantly and positively correlated with above ground biomass, and the leaf width of the youngest fully expanded leaf was the best indicator of biomass yield. Analysis of variance identified significant differences among the genotypes for all measured traits, indicating that there is genetic variation among these varieties and opportunity for selection. These results from the greenhouse and the field indicate that the leaf width of the youngest fully expanded leaf can be used to rapidly select cowpea lines with high biomass production potential.
