Interrelationship among elite germplasm of cucumber (Cucumis sativus L.) at genotypic and phenotypic level

Abstract

The experiment was conducted to work out variability, heritability, genetic advance and interrelationship using twelve genotypes of cucumber (Cucumis sativus L.). GCV and PCV were highest for number of fruits per vine; whereas lowest estimate was recorded for days to first harvesting and days to last harvesting. The high heritability showed by vine length and number of fruit per vine and as compare to other characters, whereas days to last harvesting, showed lower value of heritability. Genetic advance in percentage of mean was found highest for number of fruits per vine show that these characters are under the control of additive gene action and that environmental factors have a lesser influence on the expression of these traits, thus further development of these traits through direct selection. The path coefficient analysis revealed high and positive direct is possible effect on fruit weight and days to last harvesting. As a result, these traits turned out to be important components of fruit yield thus direct selection effective via these two traits.

Deciphering the Traits Association and Path Coefficient Analysis among Yield Attributing Traits of Snap Melon (Cucumis melo var. momordica) Genotypes

“…This suggest that direct selection based on fruits plant -1 and average fruit weight could significantly enhance the yield plant -1 . The results are accordance with the report of cucumber [17,18,19,13] and snapmelon [11]. Fruit circumference (0.9741), days to first harvest (0.6632), node to first female flower appearance (0.3591), days to first female flower appearance (0.2230), number of male flowers (0.1867) and number of female flowers (0.0036) were also exhibited positive direct effect on fruit yield.…”
