Inheritance of Stripe Pattern on Fruits and Seed Colour in 'Egusi' Melon, Coiocynthis Citrusllus L.

摘要

The inheritance patterns of stripes on fruits and seed colour were investigated using Fi. F2 and F3 populations from crosses involving three varieties of "egusi" melon, Coiocynthis citrullus L. The three varieties used were "Sewere" (S), "Barablack edge" (BB) and "Barawhite edge" (BW). They were crossed in all possible combinations including their reciprocals. Results obtained indicate that pattern of stripe on fruits is controlled by a single gene pair while seed colour is controlled by two genes (dihybrid. inheritance). Chi-square analysis of the data showed a good fit between observed and expected ratios in all the populations.
