The genotype, the environment and the genotype \u00d7 environment interaction significantly influenced all the morphological and agronomical parameters evaluated. For both years, the highest yields were observed at Elvas, whereas Cartagena and Vila real were the most suitable places to obtain crop precocity. Cartagena was the place where the filling of the seed was the fastest, probably due to the higher temperatures and radiation. The thermal time model (effective degree-days) could be used to predict the period of cowpea development, therefore predict flowering and pod maturity date. Correlation analysis showed that days to flowering, days to maturity and the seed yield vs protein content exhibited negative correlations. The highest heritability was found for plant height and pod length at Cartagena and for 100-seed weight at Elvas and Vila Real. In conclusion, the variations that exist in the studied accessions could give rise to a breeding program to develop cowpea cultivars with interesting agronomic traits.<\/jats:p>","DOI":"10.1071\/cp17071","type":"journal-article","created":{"date-parts":[[2017,8,10]],"date-time":"2017-08-10T19:42:12Z","timestamp":1502394132000},"page":"924-931","source":"Crossref","is-referenced-by-count":19,"title":["Genotype by environment interactions in cowpea (Vigna unguiculata L.
