摘要: SUMMARY Data are presented for the joint segregation of gene combinations: Dm-2/Dm-3, Dm-3/Dm-6, Dm-2/Dm-6 and Dm-6/Dm-8, following inoculation with five races B. lactucae. It is postulated that Dm-2, 3 6 comprise a tight linkage group but Dm-6 Dm-8 not linked as has been proposed previously. Information on reaction some resistant lettuce cultivars to certain lactucae new host genotypes also presented.
