The present study was conducted to exploit heterotic potential and combining ability for developing early maturing, high-yielding, good quality parthenocarpic gynoecious beit alpha cucumber hybrids tailored specific environmental conditions. experimental material comprised 11 parents which were crossed produce 28 F1 through a line × tester mating design, plus two commercial check (PKH-11 Emirstar) further evaluated yield attributes under different environments (winter summer seasons) in poly-net house. mean sum of squares due genotypes, environments, G E interaction found significant (p ≤ 0.01) all the traits, except fruit diameter. wide range variability traits provided an opportunity select suitable across environments. nature magnitude heterosis estimated over checks tester's contribution highest analysis almost studied traits. Based on results pooled it concluded that parental lines PBRK-16, PK-1 testers PBRK-8, PBRK-1 exhibited superior stable performance basis performance, GCA effects its contributing On heterosis, SCA effects, cross combinations PBRK-16 PBRK-18 have number fruits per plant. However, hybrid PBRK - 16 PBRK-8 shorter length more thickness will get least market acceptance by stakeholders. As medium size type are mostly preferred having 15-18 cm weight 125-170 g. Therefore, desirable diameter can be released cultivation house both seasons. non-additive gene low narrow-sense heritability most studied, indicating effectively utilized their improvement. Hence, these promising also segregating generations identify pure with high quality. Furthermore, year-round significantly increase farmers' profitability, strengthen food security, meet demands.

Parthenocarpy in cucumber is a complex trait regulated by various genes and phytohormones. It an important feature which helps to overcome the problem of poor fruit setting cucumbers. The present research was conducted estimate variability, correlation path analysis 15 yield quality traits using 30 advance breeding parthenocarpic lines including standard check 'Punjab Kheera 1'. genetic variability studies reported high estimates phenotypic genotypic coefficient variation for number fruits set per node plant signified improvement these with selection. High moderate heritability gains were observed length, diameter, weight, internodal vine female flowers node, plant, vitamin C content fruit. analyses provided clear picture that there direct positive effect C, flesh seed cavity ratio, pistil length on plant.
