Linkage Inheritance among 6 Genes in Cucumber
|
Abstract:
To study the linkage inheritance among gene mp for multi-pistillate flowering,de for determinate growth type,cr for crinkled leaf,gl_2 for glabrous leaf,ns for numerous spine,and Tu for tuberculate fruit in cucumber,the inbred NCG128,NCG 157,WI 2757 and NCG 042 were used as parents for 4 combinations in the experiment.The traits of these genes were measured in field and the data was analyzed with a computer program SASGENE.The result indicated that the gene mp and de,cr and gl_2,cr and Tu,Tu and gl_2,Tu and ns had linkage relationship,and the distance between them was 0.21,0.12,0.38,0.24,0.32 cM,respectively.
