| Summary: | A partial sterile line of cowpea (Vigna unguiculata (L.) Walp.) resulting from spontaneous mutation was characterised. Plants were classified based on plant morphology, pollen viability and pod set. Partial sterile plants remained green past usual maturity and had thick leathery leaves with a few fleshy 1-3 seeded pods. Reciprocal crosses indicated partial female fertility. Pollen number per anther was variable and about 77% pollen from mutant plants were normally stained with acetocarmine compared with 98% for normal plants. The proportion of fertile to partial sterile plants in segregation populations indicated that the character is controlled by a single recessive gene which is being designated as “ps”. The homozygous recessive plants bred true for partial sterility. The possible uses of this mutant are discussed. The line is being maintained as IT85D-3626. |
