瓦尔岗七星椒与13个朝天椒品种的比较与评价

Comparison And Evaluation of Waergang Qixing Pepper And 13 Red Cluster Pepper Varieties

采用单因素随机区组设计,在常德桃源县比较了瓦尔岗七星椒与13个外地朝天椒品种的田间性状,以确定瓦尔岗七星椒的品种改良方向。结果表明:瓦尔岗七星椒属晚熟品种,株形较高,果实为短牛角形,产量表现最差,为898.86kg/667m^2;在抗病性方面,高温高湿条件下瓦尔岗七星椒对疮痂病表现为感病、对疫病表现为中抗,总体抗病性较差,且极不抗倒伏。综合来看,18Z636、18Z623、17Z622、泰国艳红、七星旺和博辣天玉等6个品种相对较好;瓦尔岗七星椒在丰产性、商品性、抗病性等方面不具优势,但辣味方面优势明显,有待于品种改良,也可引进并示范栽培泰国艳红。

In order to determine the improvement direction of the Qixing Pepper in Waergang, a single factor randomized block design was used to compare the Qixing Pepper in Waergang with 13 other red cluster pepper varieties in the field. The results showed that the latematuring cultivar of Qixing Pepper in Waergang had high plant height, shorter horn shape fruit and the worst yield performance, which was 13 482.9 kg/hm2. In terms of disease resistance, under high temperature and high humidity conditions, Qixing Pepper of Waergang showed susceptibility to scab, moderate resistance to epidemic disease, poor overall disease resistance, and extremely resistant to lodging. Generally speaking, the six varieties, 18Z636, 18Z623, 17Z622, Thai Yanhong, Qixingwang and Bolatianyu, are relatively good. The Qixing Pepper in Waergang has no advantages in yield, commerciality and disease resistance, but it has obvious advantages in hot taste and needs to be improved. It can also introduce and cultivate Thai Yanhong.
