Short communication a partial male sterile mutant in cowpea
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 fl...

| description | 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. |

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.

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. Une lignée partielle de niébé (Vigna unguiculata (L.) Walp.) Résultant d'une mutation spontanée a été caractérisée. Les plantes ont été classées en fonction de la morphologie de la plante, de la viabilité du pollen et de l'ensemble des gousses. Les plantes stériles partielles sont restées vertes après la maturité habituelle et avaient des feuilles coriaces épaisses avec quelques gousses charnues 1-3 ensemencées. Les croisements réciproques indiquaient une fertilité féminine partielle. Le nombre de pollen par antre était variable et environ 77% de pollen provenant de plantes mutantes étaient normalement colorés à l'acétocarmine contre 98% pour les plantes normales. La proportion de plantes fertiles à stériles partielles dans les populations de ségrégation indique que le caractère est contrôlé par un seul gène récessif qui est désigné par "ps". Les plantes récessives homozygotes ont donné naissance à la stérilité partielle. Les utilisations possibles de ce mutant sont discutées. La ligne est maintenue en tant que IT85D-3626. 1998 2018-07-05T06:30:30Z 2018-07-05T06:30:30Z Journal Article https://hdl.handle.net/10568/96034 en fr Limited Access Singh, B. & Adu-Dapaah, H.K.
