Abstract:Crossing between a white seed coat cultivar White Coat No.1 and three red seedcoat cultivars, Yueyou 116, Shanyou 71 and Quanhua 10, which were main cultivars usedin Fujian Province, were made in order to breed high yield cultivar with white seed coatand to understand the genetics of white seed coat. The seed coat in F, was all red. In F2the segregating ratio of red to white coat in plants conformed with the segregation lawof 15: 1. Among the F3 strains derived from the F2 plantS with red seed coat, 4 to 15strains showed that the ratio of red to white was 3:1, therefore, it was inferred thatthe white seed colour was directed by two recessive genes. The white character did notlinked with yielding traits. Genetic ability of main econodric traits was in order' podnumber per plant>mature pod weight and biological yield>mature pod number.Several stable combination varieties with excellent comprehensive traitS were selected fromFa, F' and F5 strains. Two high yielding varieties were taken part in regional testing fornew peanut variaties in Fujian Province.
