Abstract
Cowpea is a warm-adapted crop which is grown and cultivated in all over the world.
Collection of cowpea germplasm accessions is important sources of genetic variability for breeding purposes or direct use by farmers.
At the Institute of plant genetic resources 302 accessions of cowpea are conserved in a genebank.
The objective of this study was to collect, characterize and evaluate a subset of cowpea (V. unguiculata L. Walp) germplasm with local and foreign origin.
The study was performed on 82 accessions using a standard set of morphological descriptors.
Days to flowering, days to maturity, plant height, number of pods per plant, weight of pods and weight of seeds per plant were the most useful parameters for discrimination purposes.
Data were collected during three years and analyzed by the statistical program SPSS. Accessions with potential for germplasm development were identified.
The earliest accessions finished vegetation cycle for 74 days.
Parts of this group are accessions with cat.
No C1E0066, C1E0069 and C1E0071 etc. which matured for shorter period than others.
The highest value of number of pods per plant (>15) were in genotypes cat.
No 95210095, A4E0084, 7540, C1E0069, etc.
Accessions with highest seed weight (>20 g 100-1 seeds) were registered at cat.
No 95210045, 95210017, C1E0070, A8E0492, etc.
The importance of linking preservation and utilization is highlighted.
