Genetic linkage map of a backcross between C. canephora P. and C. heterocalyx and autogamy gene location
We have constructed a genetic linkage map based on an interspecific cross between C. canephora and C. heterocalyx. In a population of 74 back-cross plants, self-compatibility trait and 207 AFLP markers segregations were analysed. Of these markers, 157 were assigned to 14 linkage groups covering total map length of 1404.8 cM. The self-compatibility of plants was evaluated by means of fruit setting and pollen-tube behaviour using ultraviolet fluorescence microscopy. The results obtained showed the monofactotial control of self-compatibility trait which has been mapped in a linkage group.
