It is also resistant to major diseases like anthracnose, web blight , brown blotch, Cercospora leaf spots, Septoria leaf spot, bacterial blight, as well as cowpea yellow mosaic and cowpea aphid borne mosaic. Yield trials in Mali showed 30 to 100% superiority in grain yield compared to the local and improved cultivars used as checks. Being an early maturing cultivar, it becomes ready for harvest in 70 to 75 days, while the local cultivars reached maturity in 100 to 120 days. The mean grain yields ranged from 1 ton to 1.5 ton/ha in on farm-trials. | 1676682 | PI 639260 |
