Analysis of High and Stable Yield and Related Traits of New Cotton Variety'Liaomian 21'
摘要
Abstract
The study aimed to explore the yield traits and identify key factors for increased production in the cotton cultivar'Liaomian 21'.Based on the data of 2018 to 2021 regional tests,the high yield,stable yield and related agronomic characters of the variety were analyzed using principal component analysis and path analysis.The results showed that'Liaomian 21'showed good high yield,stability and adaptability.Lint yield was significantly positively correlated with the number of bolls per plant,pre-frost flowering rate,single boll weight and lint percentage;5 principal components were extracted from the principal component analysis,and their cumulative contribution rate was 87.94%;path analysis showed that the factors affected lint yield of'Liaomian 21'were the number of bolls per plant(0.583),lint percentage(0.459),and single boll weight(0.369)in terms of contribution rate.Studies have shown that'Liaomian 21'is a cotton variety with stable yield,strong adaptability and excellent quality.It has good salt resistance and is suitable for large-scale promotion and application in the Yellow River Basin,especially in saline-alkali land.关键词
