湖北早实丰产优质板栗杂交新品系育种初探

Preliminary Discussion on Hybrid New Strain Breeding for Early - bearing and High-yield and Good Quality for Castanea mollissima BI. in Hubei

摘要:

2000～2007年间,湖北省林业科学研究院首次在我省大范围板栗资源调查的基础上,在京山虎爪山板栗资源圃有选择地开展了板栗种间杂交育种系列试验,以期培养出早实、丰产、耐贮、果实质量好的新品系。试验结果表明:选用六月暴与红毛早、处暑红(桂花香进行杂交,其杂交亲和性较强,结实率、种单个粒重都表现出明显的杂种优势。

Abstract:

Hubei Academy of Forestry firstly and selectlly carried out a serious tests on interspecies hybrid breeding for Castanea mollissima Bl.in the resource orchard of Jingshan Huzhaoshan so as to breed new strain of good quality with early-bearing and high-yield,durable storing fruits among year of 2000~2007 based on the source survey in large range in Hubei Province.The result showed that Liuyuebao and Hongmaozhao,Chushuhong Guihuaxiang for hybriding were selected.Its strong hybrid,bearing rate and per seed weight of the species presented obvious hybrid advantageous.
