英文摘要	Bitterness in cucumber fruit and foliage is due to the presence of cucurbitacins. Several genes have been described that control the trait, with bi (bi-1) making fruit and foliage bitter free and Bt (Bt-1) making the fruit highly bitter. Previous studies have reported the inheritance and molecular markers linked to bi-1 or Bt-1, but we were interested in studying the inheritance of fruit bitterness in the progeny of 2 nonbitter fruit inbred lines. The objective was to determine the inheritance of cucumber fruit and foliage bitterness and to locate them on a current linkage map using a recombinant inbred lines (RILs) population derived by crossing 9110Gt and 9930. It was concluded from the inheritance analysis that there were 2 loci controlling fruit bitterness in the population. One locus was in the same position as the location previously identified for bi-1, and another locus was for bi-3. Using a simple sequence repeat (SSR) linkage map, 2 loci for fruit bitterness in this RILs population were mapped. The locus of bi-1 was located at the region between SSR0004 and SSR02309 within the genetic distance of 5.2 cM on chromosome 6. The locus of bi-3 was placed in the region of SSR00116SSR05321 within the genetic distance of 6.3 cM on chromosome 5. The physical distances for the regions of bi-1 and bi-3 were 11,430.94 Kb with 160 predicted genes and 1528.23 Kb with 198 predicted genes, respectively. Among 160 predicted genes for bi-1, there is a terpene synthase gene named Csa008595, which was speculated as the candidate gene of bi-1.
