4个不同指天椒品种比较试验研究

目的]筛选高产优质抗逆性好的指天椒品种。方法]以从国外引进的4个指天椒品种为供试品种,对这些品种的物候期、植物学性状、商品性、抗逆性及丰产性进行比较分析。结果]4个指天椒品种均表现商品性好、植株长势旺、抗逆性较好。4个品种中,艳红、GL-5和红香为相对早熟品种,红利为较迟熟品种;艳红的抗倒能力最强,其余3个品种的抗倒能力无明显差异;4个品种均不发生青枯病;鲜椒产量以艳红最高,达到22 725.0 kg/hm2,与其他品种差异极显著,GL-5次之,为19 380.0 kg/hm2;干椒产量以红利最高,达5 827.5 kg/hm2,艳红和红香次之,分别为5 344.5和5 454.0 kg/hm2。结论]可根据指天椒的不同用途加以推广,艳红比较适合作为鲜椒品种加以推广,红利比较适合作为干椒品种加以推广。

Preliminary Report on 4 Different Cultivars of Capsicum frutescens L.

Objective] The study aimed to screen the Capsicum frutescens L.cultivars with high yield,good quality and well stress resistance.Method] With the 4 C.frutescens cultivars introduced from the abroad as the tested varieties and their phenophase,botany character,fruit quality,stress resistance and yielding ability were compared and analyzed.Result] The 4 C.frutescens cultivars showed good fruit quality,well plant growth vigor and better stress resistance.Among 4 cultivars,Yanhong,GL-5 and Hongxiang were relatively early-maturing cultivars and Hongli was relatively late-maturing cultivar;the lodging resistance ability of Yanhong was strongest and that of other 3 cultivars had no obvious difference;4 cultivars didn't occur the bacterial wilt;Yanhong had highest fresh pepper yield of 22 725.0 kg/hm2,showing a extremely significant difference with other cultivars,GL-5 was the next and had the fresh pepper yield of 19 380.0 / hm2;Hongli had the highest dry pepper yield of 5 827.5 kg/hm2,Yanhong and Hongli were next and had the dry pepper yield of 5 344.5 and 5 454.0 kg/hm2,resp.Conclusion] C.frutescens could be extended according to its different usage.Yanhong was relatively suitable to used as fresh pepper cultivar for the popularization and Hongli was relatively suitable to used as dry pepper cultivar for the popularization.
