青海乐都长辣椒提纯复壮研究

Research on Purification and Rejuvenation of Ledu Long Pepperin Qinghai

为保护和开发地方蔬菜种质资源,适应产业发展需要,采用单株-混合法,对青海乐都长辣椒进行3代的提纯复壮。结果表明:经提纯复壮后各性状得到明显提升。植株叶片披针形,叶色深绿。果形长锥形,果顶部渐尖,花萼下包,果实表面皱缩,有棱沟,果实纵径24.4 cm,横径4.23 cm,果肉厚29.99 mm。单果重55.47 g,单株结果数39.85个,千粒重9.23 g。

In order to protect and develop local vegetable germplasm resources and meet the needs of industrial development,single plant-mixing method was used to purify and rejuvenate Qinghai Ledu long pepper for three generations.The results showed that,after purification and rejuvenation,the traits were obviously improved.The leaves were lanceolate and dark green.The fruit shape was long conical,the top of the fruit was acuminate,the calyx was enclosed,the surface of the fruit was shrunken and furrowed.The fruit length was 24.4 cm,the transverse diameter was 4.23 cm,and the pulp thickness was 29.99 mm.The fruit weight was 55.47 g,the number of fruit per plant was 39.85,and the 1000-grain weight was 9.23 g.
