Time to flowering and maturity is an important adaptive feature in annual crops, including cowpeas (Vigna unguiculata (L.) Walp.). In West and Central Africa, photoperiod is the most important environmental variable affecting time to flowering in cowpea. The inheritance of time from sowing to flo...

Virus diseases cause substantial yield reduction in cowpea ( Vigna unguiculata (L.) Walp) production in West and Central Africa. Improved cowpea cultivars have been developed and distributed to various national programs but these cultivars were tested only against local virus isolates. To identif...

This study was undertaken to elucidate the nature of inheritance of the two types of drought tolerance in cowpea {Vigna unguiculata (L.) Walp} so that the drought tolerant can be effectively used in breeding programme. Three cowpea lines viz TVu 11986 willi ‘Type l' drought tolerance, Dan IIa wit...
