Gynoecious lines

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.

Eight parental lines including one gynoecious line PDMGy-201 (Gy-23) and their 28 F1 hybrids obtained from half diallel analysis were used to estimate the extent of heterosis for earliness, yield and its contributing traits in bitter gourd. The F1 hybrids developed using gynoecious line as one parents were found to be superior in performance over mid and standard parents for several earliness and yield characters.

Thirteen (Three gynoecious and ten monoecious) germplasm lines of cucumber (Cucumber sativus L.) were characterized by sodium dodecyl sulphate polyacrylamide vertical slab gel electrophoresis (SDS-PAGE). The seed protein could be resolved into total 11 bands distributed in 4 zones i.e. A, B, C and D. Zone A was divided into 5 subzones and 5 bands, zone B has 1 band C has 5 and zone D included 5 bands. Similarity index value ranged from 62% to 100% among all the genotypes. Pgyn-1 showed least similarity 68% with other genotypes.

The present experiment was carried out during Kharif (2016) at the Experimental Research Farm, Department of Vegetable Science, Dr. YS Parmar University of Horticulture and Forestry, Nauni, Solan (HP) to gather information on use of chemicals (Gibberellic acid, Silver nitrate and Silver thiosulphate) in modification of sex expression in gynoecious varieties (GYNO-1 and GYNO-2) of cucumber.

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.
