目的对川射干野生资源进行产量性状调查研究。方法文献查证川射干野生资源分布区域,走访调查分布区域生态环境,收集野生资源,进行产量性状方差分析及相关分析。结果川射干野生资源分布较广,川内较多地方均有分布,其中井研、中江的川射干具有明显的产量优势。产量性状相关分析表明,川射干产量性状与其块茎宽度、厚度相关极显著,而与长度相关不显著。结论井研、中江的川射干野生资源可以考虑作为最佳的产地或种源。提高川射干块根的宽度和厚度是高产品种的主要育种目标,单纯地增加其块根长度很难获得理想的产量效果。
Objective To investigate the yield traits of wild shoots of Chuan Shegan. Methods The literature verified the distribution area of wild radish resources, visited and investigated the distribution of regional ecological environment, collected wild resources, conducted variance analysis and correlation analysis of yield traits. Results The distribution of wild radish resources was broad, with distribution in more places in Sichuan. Among them, Jingchuan of Jingyan and Zhongjiang had obvious yield advantages. Correlation analysis of yield traits showed that the correlation between shoot yield and tuber width and thickness was significant but not significant with length. Conclusions Jingyan and Zhongjiang can be considered as the best origin or provenance of wild stems in Sichuan. Increasing the width and thickness of shoots of Radix Chuanxiong is the main breeding target of high-yielding varieties. Simply increasing the length of their roots makes it difficult to obtain the desired yield.
