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.

Ultrastructural Effect

Etiolated cotyledons of cucumber (Cucumis sativus L.) were isolated and incubated for 15 h in the dark and 48 h in the light in the presence of 10−6 g/mL 6-benzylaminopurine (6-BAP) or 3.10−6 and 10−5 g/mL cycloheximide (CHX). Cotyledons were permanently maintained on these compounds or transferred from one medium to the other after the dark period or after 6 h of the light. 6-BAP stimulates both chlorophyll synthesis and plastid differentiation. Chlorophyll synthesis is more affected than differentiation in the presence of CHX. Only some thylakoids are present in plastids treated permanently with CHX at 10−5 g/mL. At 3.10−6 g/mL, CHX inhibits the development of the stroma thylakoids and the granal stacks. The effect of CHX is particularly important during the 1st h of light; it is partially reversible. During the treatment with 6-BAP followed by CHX (or conversely), the ultrastructural effect of 10−5 g/mL CHX is removed if 6-BAP is given before the inhibitor. After 48 h the plastid ultrastructure depends particularly on the compound applied during the 1st h of light. 6-BAP and CHX are not competitive during chlorophyllogenesis. 6-BAP increases and CHX decreases the incorporation of 32P into cytoplasmic and etioplastic rRNA during the dark. During the light, 6-BAP increases the incorporation in chloroplastic rRNA only and CHX decreases the incorporation in cytoplasmic rRNA only. The modes of action of CHX and its relations with 6-BAP are discussed.

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.

Cropping Seasons

The intensity of sex expression is important in crops, including cucumber, since sex form and flowering have direct effects on date of harvesting and yield. Two groups of cucumber comprising a native variety (Odukpani) and elite varieties (Griffaton, Poinsett, Ashley, Marketmore and Monarch) were evaluated in 2015 and 2016 cropping seasons at the Teaching and Research Farm, College of Agriculture, Garkawa, Plateau State; to assess flowering, sex expression and some yield traits. The experimental design was randomized complete block design with the 6 cucumber varieties as the treatments, replicated five times. The two groups differed significantly (p < 0.05) in phonological, flowering and yield traits assessed. The elite varieties were superior with respect to flowering traits, as they flowered early. The intra-population hierarchical cluster analysis of quantitative traits grouped the elite varieties in one main cluster and the native variety (Odukpani) alienated as an outlier. The cluster plots showed that Odukpani was robust in vegetative growth, produced few but larger fruit size and flowering was delayed for over two weeks. Conversely, the elite varieties flowered early, produced more flowers and recorded superior number of fruits per plant. The profuse production of pistillate flowers by the elite varieties had pronounced yield advantage over the local variety. Hybridization between the two groups of cucumber would make a mark in the drive for sustainable cucumber fruit yield.
