Srap markers for fruit shape in cucumber

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.
