520 _aIn a second part. Variation for segregation and recombination was analyzed in crosses involving 13 bean parents from different gene pools and races. These parents revealed a moderate level of RFLPs (65 percent) in crosses it between Andean x Middle American compared with 16.7 percent in crosses between gene pools. EcoRV and Hindlll digests detected higher leveJs of polymorphism in crosses between Middle American and Andean genotypes, however EcoRI and Hindlll digests were more effficient in detecting higher levels of RFLP variation in crosses between Andean genotupes. Thesegregation of a set of RFLP markers belonging to linkage groups D5 and D 78 were analyzed in 11 F2 populations derived from Middle American pour Andean and Andean pour Andean crosses. The analyses showed an average level of 7.1 percent ofsegregation distortion for RFLPs compared with 28.6 percent for isozyme markersPreferential transmission of Middle American alleles were detected in all crosses analyzed between gene pools. The levels of recombination were highly variable among a subset of four of the 11 populations analyzed, which suggests that genetic variation for recombination may exist in common bean.
