Abstract

Fruit shape is one of the most important quality factors in many domesticated plants. In this study, we used bulked segregate analysis (BSA) to identify two sequence-related amplified polymorphism (SRAP) markers linked to fruit shape in cucumber (Cucumis sativus L.). A segregating F2 population of 130 plants from a cross (B-2-2×Y-3) of B-2-2 with long fruit shape trait and Y-3 with round fruit shape trait was used. Correlation and regression analysis showed that markers ME21/EM18M600 and ME9OD3M190 were linked closely to the allele of round at the fruit shape locus. Marker ME21/EM18M600 accounted for 49.5% of the phenotypic variation in fruit shape, and ME21/EM18M600 accounted for 33.1% of the phenotypic variation.
