Fig. 1. (A) Restriction fragment length polymorphism banding patterns for DraI - digested DNA from the 12 original recurrent selection parents hybridized with the oat cDNA clone CDO 82. Arrows designated (a) represent alleles of an unmapped locus and arrows designated (b) represent alleles of a locus that maps to linkage group 6. (B) Restriction fragment length polymorphism banding patterns for DraI - digested DNA from the 21 Cycle 7 parents hybridized with the oat cDNA clone CDO 82. Arrows designated (a) represent alleles of an unmapped locus and arrows designated (b) represent alleles of a locus that maps to linkage group 6.
