The inheritance pattern of gynoecious sex expression in cucumber was studied by utilizing a gynoecious line (GBS-1) and two monoecious lines (Pusa Uday and Punjab Naveen). Crosses were made between gynoecious line (GBS-1) and monoecious lines (Pusa Uday and Punjab Naveen). The F1 and F2 population along with parental lines were evaluated to study the inheritance of this trait. All F1 hybrids showed gynoecious sex in both crosses and in the F2 generation, the observed distribution of plant phenotypes fitted the expected mendelian ratio of 3 (gynocious plant) : 1 (monoecious plant). The segregation of plant sex types suggested monogenic dominant control of gynoecious sex form in cucumber using genotype GBS-1.

Gibberellic acid (GA3) promoted maleness and 2-Chloroethyl phosphonic acid (ethephon) promoted femaleness in cucumber (Cucumis sativus L.) cv Regal 446 seedlings when treated with water, ethephon (250 or 350 ppm) or GA3 (1000 or 2000 ppm) at the l-, 2-, or 3-leaf stage. Seedlings treated with ethephon at all stages produced more female flowers than those with water or GA3 treatments. GA3-treated seedlings produced significantly more male flowers than water treatments, at all developmental stages. The differential response of cucumber seedlings treated at different stages indicated the importance of timing growth regulator applications.

Map Location

Cross progeny (F3 and BC) of a Cucumis sativus var. sativus (GY 14) × C. sativus var. hardwickii (PI 183967) mating were used in conjunction with RFLP analysis to identify regions of the genome influencing yield and fruit quality, and to test the consistency of QTLs over environments and generations. QTLs affecting earliness, sex expression (F), fruit yield, and fruit size were identified. The number and map location of these QTLs was consistent over environments (years and plant densities). Differences in number and map location of QTLs were found when F3 and BC families were compared. Some of these differences could be attributed to disparities in population size (102 and 59 for F3 and BC families, respectively), dominance, and the amount of genetic information available (F3 > BC). Two shared chromosomes regions were identified that conditioned days to anthesis, fruit number, and weight. One of these regions coincided with the QTL affecting number of barren nodes, while the other was near the F-locus. Three to five QTLs were found to control fruit length (L), diameter (D), and L/D ratio. Depending on the locus, QTLs affecting fruit size appeared to express themselves with various degrees of dominance according to the direction of dominance observed in either parent.
