The Main Gourd Germplasm in South China Based on Morphological Charaters and SRAP Markers

doi:10.7668/hbnxb.2013.S1.002

Abstract

Abstract: The genetic diversity of 13 main gourd vegetable in South China were analyzed using 9 morphological characters and SRAP markers with 20 pairs of primers. The results showed that there were the significantly different in 9 morphological characters. A total of 328 polymorphism fragments and 2 common fragments of 13 main gourd vegetables were generated from 20 pairs of SRAP primers. The polymorphism rate reached 99%,the genetic similarity values were between 0. 140-0. 993.The correlation coefficient was 0.576( P=0. 05,this study reveals) of the phenotypic traits and SRAP markers,the result revealed that there were the significantly relation between the phenotypic traits and SRAP markers. The correlation analysis could help our clarify the genetic relation of main gourd vegetable in South China and provide the scientic basis for the study of genetic relation and breeding of gourd vegetable in the Cucurbitacea.

Key words: South China, Gourd vegetable, SRAP, Genetic relation
