胡麻种子产量与主要农艺性状的多重分析
Multiple Analysis of Seed Yield and Main Agronomic Traits in Flax
摘要
Abstract
[Objective] To explore the main agronomic traits affecting seed production of Linum usitatissimum L.,and to further provide scientific basis for breeding high-yield varieties.[Method] The correlation analysis,multiple regression analysis and path analysis between seed yield and eight main agronomic traits of 343 L.usitatissimum germplasm were carried out,including plant height,stem length,branch number,bolls per plant,seeds per boll,1 000-seed weight,flowering days,number of growing days.[Result] The variation coefficient of main agronomic traits was 3.825％-24.928％ with the average coefficient of variation being 16.76％,the average genetic diversity index was 1.97.The impact of three factors(capsule number per plant,seeds per capsule,1 000-seed weight) on L.usitatissimum seed yield reached 92.17％ or more,which could well predicted the change of seed production.Capsule number per plant and branch number had extremely significant positive correlation (P ＜0.01) to seed yield,the direct effect of capsule number per plant on seed yield was the largest (P =0.742) with its correlation coefficient being the highest (r =0.776).[Conclusion] Capsule number per plant was the main agronomic trait determining the seed yield.关键词
