Correlated inheritance of fruit neck with fruit length and linkage relations with 10 other characteristics of cucumber

Summary The inheritance of cucumber fruit neck size and its linkage relationships with the fruit length and 10 other characteristics was investigated. Frequency distributions and the means of generations indicate intermediate inheritance for neck size and fruit lenght. Correlation and regression analysis suggest strong linkage between fruit neck size and fruit length. Chi square analysis of the F₂ and BC generations indicate independent assortment of the fruit neck size and the following characters: bitterness, female sex expression, spine color, spine size, warted fruit, uniform color of immature fruit, mature fruit color, dull fruit skin, epidermal structure, and powdery mildew resistance.
