甘南高寒区藜麦种质适应性评价
Evaluation of germplasm adaptability of quinoa in the alpine region of Gannan Prefecture
摘要
Abstract
[Objective]The aim of the study is to investigate the adaptive performance of the test varieties in the alpine zone of Gannan Prefecture,Gansu Province,and to screen out the most suitable quinoa varieties in the alpine zone of Gannan Prefecture,so as to provide a theoretical basis for the scientific cultivation and industrial development of quinoa in the region and to provide scientific support for the development of quinoa cultivation in the whole coun-try.[Method]13 quinoa varieties were taken as materials.Their phenological period,agronomic traits,yield indexes,resistance to fall and disease,as well as nutritional quality,etc.were measured and recorded,and the cluster analysis method and the affiliation function were applied to categorize and evaluate these varieties.[Result]All 13 selected quinoa materials could complete the whole fertility period in the alpine area of Gannan Prefecture,Gansu Province,but the fertility period,agronomic traits and nutritional quality of different varieties were different.Ji 4 and Longli No.1 had high yields,high thousand-grain weights and their nutritional quality was high,so they could be put into the production of high-yield and high-quality raw grains.Longli No.3 and ornamental red quinoa although yield was low,but had the characteristics of ornamental quinoa,and thus could be applied to ornamental.[Conclusion]Comprehen-sive analysis of the traits showed that Ji4 had a short fertility period(120 d),high yield(2 108.1 kg/hm2),high thou-sand grain weight(4.01 g)and good nutritional quality,and was the most suitable variety for the alpine zone of Gan-nan Prefecture,and could be widely promoted in the region.关键词
