Fruit setting, inheritance of nut colour, germination and early seedling growth of Kola (Cola nitida (Vent) Schott and Endl)
1978
Osei, J.K.
In a diallel cross involving six Kola trees, two from each of the cultivars, Laboshie white, Kumasi white, Kade pink, the self compatible Kade pink cultivar was the most efficient female but the least efficient male parent for fruitset. The frequency of red, white, and pink nuts that segregated in the progeny of the various crosses suggest that a single locus with multiple alleles controls the inheritance of Kola nut colour. At physiological fruit maturity, freshly harvested nuts of the different cultivars showed varying degrees of dormancy when sowed. Storage of nuts for two months improved their germination rates suggesting dormancy breakdown. The most vigorous seedlings were from nuts of the progeny from crosses between the local cultivars, Kade pink and Kumasi white
