2020-2024年四川省区域试验小麦产量及主要农艺性状分析
Analysis of Wheat Yield and Main Agronomic Traits in Sichuan Regional Trial from 2020 to 2024
摘要
Abstract
[Objective]This study aims to provide a theoretical basis for the breeding of new wheat variet-ies and the promotion of wheat production in Sichuan.[Method]Based on the data from the Sichuan Re-gional wheat trials from 2020 to 2024,the changing trends in wheat yield and main agronomic traits were analyzed.[Result]The coefficients of variation for wheat yield and main agronomic traits in Sichuan were relatively small,ranging from 0.93%to 5.04%.Over the years,the whole growth period,plant height,effective panicle number per unit area,and grain number per panicle showed a slow increasing trend,while the thousand grain weight exhibited a slow decreasing trend.Wheat yield increased gradu-ally year by year,with an average annual increase of 68.52 kg/hm2.[Conclusion]Over the five years,wheat yield in Sichuan increased slowly.The effective panicle number per unit area and grain number per panicle were the main factors contributing to the increase in wheat yield.关键词
