Parents and hybrids differed significantly for gca effect. UAE 3 and UAE 20 were found to be the best general combiners for 50% day of flowering and number of fruits per plant. While UAE 25, UAE 3 and UAE 5 were best for seeds weight per fruit and yield per plant; between tester lines, UAE 19 shown good gca effect of number of seeds per fruit and fruit yield per plant, when UAE 22 is good for number of seeds per fruit. The most heterotic combinations for number of fruits per plant were those including UAE 22 in their combination. The same hybrids have shown medium heterobeltiosis effect for fruit length and in some of them (H22-20 and H22-5) was observed highest heterobeltiosis of yield per plant, varied from 59.90 to 77.57 respectively. The highest depression (non heter...

Walp.) varieties resistant to Striga gesnerioides in Burkina Faso. Despite these efforts, the resistant genotypes developed still express differential responses to Striga gesnerioides in different zones of the country. This suggests existence of intraspecific variability within the parasite. The objective of this study was to assess the intraspecific variability of cowpea genotypes to Striga gesnerioides infection in Burkina Faso. Ten cowpea varieties were screened over two consecutive years, under artificial infestation with 30 ecotypes of Striga seeds at Kamboinsé research station, in a screenhouse in Burkina Faso. Cowpea varieties used included Moussa local, Komsaré and KVx404-8-1, which are susceptible to all Striga ecotypes; and varieties B301, IT93K-693-2 and IT82D-849, which are free from all Striga ecotypes infestation. Cowpea varieties Tiligré, 524B, local Gorom and Niizwè had specific reactions de...
