油茶是我国南方的主要木本油料树种。当前影响油茶丰产、稳产的原因较多,其中,油茶炭疽病的危害是主要原因之一。据在油茶主要产区调查,油茶炭疽病的发病率一般在30％左右,中病落果占落果15％左右,严重的可达20-30％。攸县油茶(Camellia yuhsienensis,Ha)原是湖南省攸县的一种野生油茶,1962年后在进行油茶抗炭疽病品种调查中发现,混生在普通油茶林内的攸县油茶不感染此病。通过试验初步证明:攸县油茶是一个抗炭疽病物种。此外,还对它的生物学特性和栽培技术进行了一些观测,在攸县油茶与普通油茶、小叶油茶和浙江红花油茶等8个物种、20个地方
Camellia is the main woody fuel tree species in southern China. Currently, there are many reasons that affect the yield and stability of Camellia oleifera. One of the main reasons is the harm of Anthracnose of Camellia oleifera. According to the survey of the main producing areas of camellia, the incidence of anthracnose in camellia is generally about 30%, the disease is accounted for 15% or so, and the severity is up to 20-30%. Camellia yuhsienensis (Ha) was originally a kind of wild camellia in Youxian County of Hunan Province. After the investigation of the resistance of Camellia oleifera to anthracnose in 1962, it was found that Youxian camellia mixed in common Camellia oleifera forest did not infect the disease. Preliminary test proved: Youxian Camellia is an anti-anthracnose species. In addition, some of its biological characteristics and cultivation techniques were observed in Youxian Camellia oleifera and common tea, small leaf tea and Zhejiang safflower Camellia 8 species, 20 places
