几种金花茶组植物的远缘杂交育种
Distant hybridization breeding with several plants of Camellia nitidissima
摘要
Abstract
In order to create new germplasm of Camellia nitidissima Chi,30 hybridized combinations was carried out with 4 species of Sect. nitidissima(C.chrysantha var.Longistyla,C.impressinervis Chang et S.Y.Liang,C.chrysanthoides'Huangzun',and C.chry-santha (Hu) Tuyama),3 species of Sect. oleifera which included C.chekiangoleosa Hu,and 7 species or varieties of Sect. japonica including C.azalea Wei,C.japonica 'Amplesicauzsis',C.japonica L. var. 'Kramer′s Supreme', C.japonica var. 'Dormi' and C. japonica L. var. 'Hiemalis' as parents. The results showed that 8 hybridized combinations of high compatibility was obtained and 513 hybridized seeds was collected in 2 years. The hybrid fruit rate of C.chrysanthoides'Huangzun' ♀×C.chrysantha var. Longisty-la ♂ was the highest,ranging from 19.0% to 37.3%. The size, shape and colour of hybrid fruits were closer to features of female parent. And size,shape and gloss of the leaf of 1-year-old hybrid seedling showed intermediate characteristics of parents.关键词
