 ABSTRACT

As part of an ongoing breeding programme aimed at improving the mucilage content of high yielding local okra cultivars, crosses were made using three local okra Abelmoschus esculentus (L) Moench cultivars to work out the pattern of inheritance of fruit skin colour in some Nigerian local okra cultivars. Okra with deep green skin colour are considered more mucilaginous than others and okra consumers show appreciable preference for them. The results confirmed that fruit skin colour in okra is monogenically controlled and the recessive genes involved form a multiple allelic series. The genotypes of the genes involved are suggested as well as their dominance hierarchy. Therefore transferring the deep green colour from Awgu early, an elite cultivar, to other identified cultivars will be quite easy and fast. The results also failed to agree with some of the reports on the inheritance of okra fruit skin colour involving some exotic okra cultivars, thereby contributing to the resolution of some of the existing controversies on the pattern of inheritance of this trait.

 

Key words: Local Okra, Abelmoschus esculentus, fruit skin colour, inheritance.
