Grey Correlation Degree and Stability Analysis of New Varieties of Tartary Buckwheat in Different Climate Types of Mountainous Areas in Southern Ningxia
摘要
Abstract
Multiple experiments were conducted on 5 new varieties of tartary buckwheat crops in 5 counties(districts)for 3 consecutive years,targeting different climate types and precipitation levels in the southern mountainous areas of Ningxia.The morphological characteristics of the tested varieties were comprehensively observed.The field density,plant height,number of primary branches,number of main stem nodes,number of grains per plant,grain weight per plant,thousand grain weight,and grain yield were recorded and measured.Using a combination of grey correlation analysis and AMMI stability a-nalysis,a comprehensive evaluation was conducted on the main trait indicators and multi year pilot yield of varieties.The results showed that the correlation between yield and main factors was in the order of density>plant height>number of main stem nodes>number of grains per plant>grain weight per plant>number of first level branches>thousand grain quali-ty.Through the analysis of equal weight correlation degree and weighted correlation degree,combined with the yield of mul-tiple varieties,Jinqiao2 and Qianheiqiao5 varieties with good yield stability and ecological adaptability suitable for planting in the southern mountainous areas of Ningxia were selected.关键词
