摘要:

应用主成份回归分析对16个毛竹种源的鲜笋产量、质量、新竹胸径、单株竹重、总竹重和抗性等性状进行定量的综合评价。筛选出综合性状优良的Ⅰ类种源4个,即福建武夷、福建建瓯、福建沙县和江西上饶种源。中选种源的鲜笋重大于群体平均值17.21%~16.42% ,8种人体必需氨基酸含量平均增益15.01% ,感病虫指数低于平均值24.93%~63.37%。

Abstract:

By using principle component analysis , multi-properties of 16 provenances of Phyllostachys heterocycla cv.pubescens, such as the output and quality of fresh shouting, the DBH of new bamboo, total weight and anti-pest ability, were evaluated synthetic ally. As a result, 4 good provenances were selected out, which were Wuyi, Jian'ou and Shaxian in Fujian Province and Shangyao in Jiangxi Province. For the selected provenances, the weight of fresh shooting was 17.21%~15.42% larger than the mean weight of community, the average toner of contents of 8 necessary amino acids was 15.01%, and the index of diseases was 24.93%~63.37% lower than the mean.

Key words: Phyllostachy heterocycla cv. pubescens provenance, Synthetic selection of multi-properties, Hereditary toner
