Abstract
Four allelic pairs were found to segregate from the cross between two mung bean varieties:rrGGSSdd×RRggssDD.
R.rr stands for red versus green cotyledons, hypocotyl and top of leaflet stalk, and for beige yellow versus bright yellow flowers. Seed coat differences areG.-gg for green versus yellow (or brownish) basic colour,S.-ss for spotted (mottled) versus non-spotted (self colour), andD.-dd for dull versus shiny surface.
In the spotted class (S.), R.-rr conditions “spot covered” (SS) and “dark spotted” (Ss) versus “light spotted” (SS andSs). Consequently, the F1 is “dark spotted”.
The recombination value betweenR-r andD-d was 15%.
The findings are compared with data from litterature onPhaseolus aureus and its close relatives.
