摘要
为加快北部边缘区油茶生产,选育适宜豫南山区栽培的优良油茶品种,通过对引种油茶长林系列的8个果实性状进行分析,采用主成分分析法评价各品种的综合表现。结果表明：长林系列的8个果实性状均呈正态分布,各性状在品种内存在不同程度的变异,其中产果量、单位面积产果量的变异系数均超过48%,单果重、单果鲜籽重的变异系数在12%~32%之间,其他4个性状遗传稳定性较强;除产果量外,其他性状在品种间均存在一定差异。根据果实性状的差异,可将9个品种划分为不同的类型,综合评价显示,53号表现最好,品种选择潜力较大,可做主栽品种,23号、18号、40号、4号、3号表现一般,21号、166号、27号表现最差。
To speed up Camellia oleifera production and breed suitable cultivation varieties of C. oleifera in north marginal distribution areas in south Henan province,by using principal component analysis method,the comprehensive performance of nine introduced Chang＇lin varieties based on the analysis of eight difference fruits traits was evaluted. The results showed that,eight fruit traits of Chang＇lin varieties all showed normal distribution,there was different degree of variation of all traits within species,variation coefficients of fruit production,fruit production per unit area were more than 48%,of fruit weight,fruit fresh seed weight were between 12% to 32%,other four traits had strong genetic stability. Except fruit production,other traits all presented differences among varieties. Nine varieties could be divide into several types depend on the differences of eight fruit traits,comprehensive evaluation displayed that No.53 as main cultivate species had the best performance and great variety selection potential,No.23,No.18,No.40,No.4 and No.3 had general performance,No.21,No.166 and No.27 had the worst performance.
