“…Seed coat colour is a major trait that affects consumer acceptability in cowpea. Its preference and use patterns differ from one region to another (Egbadzor et al, 2015). Both TVu11953 and Ife Brown were true breeding for mottled red and brown seed coat colours.…”

Callosobruchus maculatus Fab. is a major threat to cowpea production reducing the quality, quantity and market value of cowpea grains. A cheap and easy identification method would be a valuable tool in identifying and breeding resistant genotypes in the vast cowpea germplasm. Hence, the purpose of the study was to identify and evaluate the genetics of cowpea traits between resistant and susceptible plant genotypes to C. maculatus. Contrasting qualitative and quantitative traits in C. maculatus resistant and susceptible parents were evaluated in 72 F 2 progeny cowpea plants. Heritability, segregation and association of investigated traits with the C. maculatus resistant performance of the F 2 cowpea genotypes were evaluated to determine closely related traits with C. maculatus resistance. Results from the study showed high heritability for all cowpea quantitative traits except leaf petiole length. Both Mendelian inheritance and non-Mendelian inheritance were observed among qualitative traits. However, association evaluation between cowpea traits and mean bruchid development period, percentage adult emergence and oviposition preference were weak (r < 0.5) and not significant (p < 0.05). This indicates that C. maculatus resistance in cowpea may be attributed to factors other than morphological variations.

Cowpea is an underutilized legume that has been cultivating in Indonesia. But, the availability of cowpea variety is limited. Cowpea breeding program is started with gene source characterization of germplasm. This research aims to study the yield and its supported component variability of cowpea germplasm. One hundred and fifty cowpea accessions were planted using randomized block design with two replications. Observation was done for days of flowering, days of maturity, plant height, number of branches, number of pods per plant, pod length, number of seeds per pod, seed weights per plant, 100 seeds weight, and seed weights per plot. Statistic descriptive, analysis of variance, and was analyzed with MSTAT 1.4 version software, while path analysis was done with SPSS 19 version. Days of flowering was ranged 32-53 das, days of maturity 60-79 das, plant height 16-51.3 cm, number of branches 0-5, number of pods per plant 13-93, pod length 9.1-22.8 cm, number of seeds per pod 12-20, seed weight 7.47-76.17 g per plant, 100 seeds weight 4.19-18.5 g, and seed weight per plot 45.61-346.58 g. There were significant differences between the genotype in leaf length x width, plant height, pod length, number of pods per plant, weight of 100 seeds, and seed weight per plot. All of the observed characters were correlated highly significant to yield, except days of maturity, leaf length x width, and pod length which correlated significantly, also number of branches and number of seeds per pod which not correlated significantly to yield. Selection was held for yield character using 20% selection index and there were 19 accessions selected, with 269.58-326.48 g seed yield per plot.

Cowpea (Vigna unguiculata (L.) Walp.) is a legume with a constant rate of cultivation in Southern European countries. Consumer demand for cowpea worldwide is rising due to its nutritional content, while Europe is constantly attempting to reduce the deficit in the production of pulses and invest in new, healthy food market products. Although the climatic conditions that prevail in Europe are not so harsh in terms of heat and drought as in the tropical climates where cowpea is mainly cultivated, cowpea confronts with a plethora of abiotic and biotic stresses and yield-limiting factors in Southern European countries. In this paper, we summarize the main constraints for cowpea cultivation in Europe and the breeding methods that have been or can be used. A special mention is made of the availability plant genetic resources (PGRs) and their potential for breeding purposes, aiming to promote more sustainable cropping systems as climatic shifts become more frequent and fiercer, and environmental degradation expands worldwide.
