Evaluation of cucumber hybrids

Three field experiments were conducted to assess the effect of planting date on the incidence of viral diseases and the severity and the susceptibility of the cultivars. Two cultivars of cucumber (Hybrid Tokyo F1 and Poinsett) and one local variety of zucchini (Bolle) were used for the evaluation in May-July 2014, September-November 2014, and February-April 2015.

The present investigation was under taken with the objectives to estimate genetic variability, heritability and genetic advance for yield and yield contributing components of cucumber. The experimental materials for this investigation were fourteen genotypes of cucumber consisting of parthenocarpic, gynoecious and monecious germplasms crossed in line × tester mating design produced thirty three hybrids (F1). Thirty three F1 crosses along with their parents were evaluated in two environments viz.

Fifteen gynoecious parthenocarpic hybrids hybrids/lines of cucumber (Cucumis sativus L.) were evaluated under polyhouse (fifty percent shade/naturally ventilated) conditions for yield and quality. The genotypic and phenotypic coefficient of variations were highest for nodal position of first female flower, number fruits, fruit weight and fruit yield per plant which indicates maximum variability is existing in the genotypes. High genetic advance as per cent mean was observed for most of the characters, indicating that these characters are controlled by additive gene action.

Studies on heterosis in cucumber (Cucumis sativus L.) was undertaken at ZAHRS, Navule, Shivamogga district, Karnataka during kharif and rabi seasons of year 2016-17. A total of 27 crosses were developed by crossing with nine lines with each of three testers. All the crosses were evaluated along with the parents in randomized block design with two replications. The hybrid Pebkamal × Haveri Local reported the significant negative heterobeltiosis for days to first female flower appearance, node at which first male and female flower appear.

The effectiveness of different arbuscular mycorrhizal fungi (AMF) on different hybrid cucumber cultivars has not been well documented, even under normal seedling conditions. The present study therefore aimed to evaluate colonization, nutrient uptake, dependency, and other seedling traits of 4 cucumber hybrids.
