胡椒属野生近缘种'芦子'鉴定评价及创新利用

摘要

以大叶种胡椒(Type Lampong)为对照,对胡椒属野生近缘种质资源'芦子'(Piper betle L.)的植物学性状、 农艺性状及抗逆性状(抗寒、 抗病)等主要性状进行鉴定评价.结果表明:野生近缘种质'芦子'长势强,冠幅大,果穗长,座果率高,抗寒、 抗病能力较强,农艺性状及抗性明显优异大叶种胡椒;通过对'芦子'种质资源的无性繁殖品种改良技术进行探究,说明'芦子'野生近缘种质资源是胡椒品种改良较好的中间材料,将为胡椒种质资源创新利用及胡椒产业发展奠定良好的基因基础.%Compared with P. nigrum " Lampong Type" (CK), botany characteristics, agronomic characteristics and resistance characteristics (such as cold resistance and disease resistance)of "Luzi"(Piper betle L.) was evaluated in this paper. The result showed that the agronomic and resistance characteristics of 'Luzi', with strong growth, big crown width, long ear, high fruit setting ratio, high cold and disease resistance, was better than that of P. nigrum "Lampong Type" . According the research of improvement technologies of cultivars through asexual propagating can be used as an good intermediate material for variety improvement of pepper, which provide genetic basis for further innovation of pepper germplasm resources and improvement of pepper industry.
