Linkage of Male Sterility and Sex Expression Genes in Cucumber

R. W. Robinson

New York Agricultural Experiment Station, Geneva, NY 14456

A male sterile cucumber, obtained from N. Nakamura, was pollinated with the cultivar 'Lemon'. Linkage was detected between male sterility and the m gene for monoecious vs. andromonoecious sex expression and the l locule number gene (Table 1). The male sterile gene is most closely linked with the m gene. This segment of the chromosome is already well endowed with genes, or a very pleiotropic allele, and it may be very genetically active. In another cross, male sterility segregated independently of the gl gene.

Table 1. Linkage tests with the male sterile, m, and l genes.
