Study on Genetic Variability, Heritability and Genetic Divergence for Character Association in Cucumber (Cucumis sativus L.)  under Prayagraj Agro – Climatic Conditions

Abstract: Momordica charantia L. and Cucumis sativus L. are excellent fruit vegetables in nature having iron content, as an essential constituent required for good health of humans. The iron content of the vegetables may vary from place to place depending on the soil, rainfall and other climatic conditions prevailing in that place. It was thought necessary to find out whether the environmental conditions in the nine agro-climatic zones of Maharashtra have any impact on the iron content of these fruit vegetables. The fruit vegetables were collected from various places from nine agro-climatic zones of Maharashtra classified based on rainfall, soil type and the vegetation. It was found that fruits of Momordica charantia L. showed comparatively more nutraceutical content than the fruits of Cucumis sativus L. collected in same season. It was also observed that in the nine agro-climatic zones of Maharashtra studied, the fruits of Momordica charantia L collected from Karjat of North Konkan Coastal Zone showed maximum Iron content, while fruits collected from Igatpuri of Western Ghat Zone and Nashik of Western Maharashtra Plain (Transaction 2) zone showed minimum iron content. In case of Cucumis sativus L., fruits collected from Wardha of Central Vidarbha (Moderate rainfall) zone region showed maximum iron content, while fruits collected from Surgana of Sub-montane (Transition 1) Zone showed minimum iron content. Keywords: Nutraceuticals, Momordica charantia L., Cucumis sativus L. Environmental factors, Iron content, Agroclimatic zones of Maharashtra.

Genetic variability in a crop population is important for successful plant breeding. Eight cucumber (Cucumis sativus L.) genotypes namely Green Long, Simran, Bhaktapur Local, Saihni-2, Ninja-179, Garima, Farmer’s variety and wild genotype were evaluated at Lamahi Municipality, Dang district of Nepal to estimate the magnitude of their genetic variability and heritability. Analysis of variance revealed significant differences among genotypes for growth and yield traits. The estimates of genotypic coefficient of variation (GCV) and phenotypic coefficient of variation (PCV) were highest for weight of fruit whereas traits namely fruit length, fruit diameter and days to maturity had medium value for both GCV and PCV. Broad sense heritability estimates ranged from 0.74 for fruit diameter to 0.98 for days to germination. Fruit yield showed high significant positive correlation with fruit diameter (r= 0.649) and negative significant correlation (r= -0.538) with days to flowering. Traits namely weight per fruit, days of germination, no. of flower and days to flowering can be used effectively in selection process of crop improvement program as they had high GCV, PCV and heritability along with high genetic advance as percentage of mean.
