羊角椒‘邯辣1号’的选育试验研究

Study on Purification and Rejuvenation of Jize Yangjiao Pepper ’Hanla 1’

为解决鸡泽羊角椒品种退化严重,产量、品质和抗性下降的问题,利用5年时间,通过2次单株选择、品系初选、品种比较、生产试验等一系列过程,对鸡泽羊角椒进行了提纯复壮,得到了羊角椒品种‘邯辣1号’。该品种植株整齐一致、株型更加紧凑,果实横径、纵径、果肉厚度和单株结果数等经济指标均显著提高,折合产量为40 185 kg·hm^(-2),平均增产39.6%,在一定程度上改变了鸡泽辣椒品种混杂、产量低、辣味淡、干物质含量低等缺陷,有效地保护了这一地方品种,并将其作为原原种和优良亲本在生产和育种研究中得到应用。

In order to solve the problem of Jize Yangjiao pepper’s serious degradation of varieties,reduced yield,quality and resistance.The purification and rejuvenation of Jize Yangjiao pepper ’Hanla 1’ was carried out in 5 years through the secondary single plant selection method.After purification,the plants were neat and consistent,the plant type was more compact,and the indexes of fruit transverse diameter,longitudinal diameter,flesh thickness and fruit number per plant were significantly improved.Equivalent to40 185 kg·hm^(-2),the average yield increase rate was 39.6%.Retain the original varieties of thin fruit skin,thick fruit flesh,oil,seed fragrance and other outstanding excellent characteristics.To some extent,this study changed the defects of jize pepper,such as mixed varieties,low yield,light spicy taste and low dry matter content,has reached the purpose of purification and revitalization,effectively protect this local variety,it can be used as the original seed in production and breeding research.
