抄録

Polymorphisms were observed in 14 enzyme systems in the following Lactuca species, lettuce, L. sativa, and its relative wild species, L. serriola, L. saligna, L. virosa and L. indica; 6 loci of the 3 enzymes, GOT, PGI and 6-PDH, were found to be dimeric. The segregation analysis of the F2 progeny between lettuce and L. serriola revealed 4 loci, Got-1, Got-2, Pgi-2 and Pdh-2 and a linkage among 3 loci, Got-2, Pgi-2 and Pdh-2. Band intensity of the somatic hybrid (hexaploid) between lettuce and L. indica showed that the hybrid is composed of 4 genomes of lettuce and 2 genomes of L. indica. Thus, the genes in the 6 loci are considered to be useful genetic markers for the breeding of lettuce.
