Abstract
A trypsin inhibitor locus (Tri) has been mapped close to Vc-2 on Pisum (pea) linkage group 5 using recombinant inbred lines derived from cro sses of genotypes showing qualitative variation in seed trypsin inhibi tors. F-2 seed populations derived from crosses between lines showing qualitative variation in trypsin inhibitors as well as quantitative va riation in inhibitor activity showed an association between the segreg ation of the structural variation and relative activity levels. Clones complementary to Pisum trypsin inhibitor mRNA were used in hybridizat ion analyses which showed that the segregation of protein polymorphism s reflected directly the segregation of polymorphisms associated with the structural genes.
