不同遗传背景BC2代胡麻农艺及品质性状的分析
Analysis of Agronomic and Quality Traits of BC2 Generation Flax with Different Genetic Backgrounds
摘要
Abstract
To create new flax germplasm with high alpha-linolenic acid content and other excellent traits,and to increase the added value of flaxseed products,five imported high-linolenic acid mutant materials(ZM)were crossed and backcrossed with local varieties to construct the corresponding backcrossing population(BC2),and their agronomic and quality traits were comprehensively analyzed.The results showed that the plant heights of'Ya 2210'and'Ya 2211'were both higher than those of their parents.The number of effective branches of'Ya 2204'and'Ya 2211'was higher than that of their parents.Moreover,the number of effective fruits,the number of grains per fruit and the yield per plant of'Ya 2211'were also higher than those of their parents.The 1000-grain weight of'Ya 2204','Ya 2206','Ya 2210'and'Ya 2211'was between that of their parents.The crude protein content of'Ya 2206'was higher than that of both parents.The crude fat and oleic acid contents of'Ya 2207'and'Ya 2211'were between those of both parents.The linoleic acid content of'Ya 2206'and'Ya 2210'was lower than that of both parents.The linolenic acid content of'Ya 2203','Ya 2209'and'Ya 2210'was between that of both parents.The lignan content of'Ya 2202'was significantly higher than that of both parents.Correlation analysis indicated that the number of effective branches was extremely significantly positively correlated with the number of effective fruits and the yield per plant.The number of effective fruits was significantly positively correlated with linolenic acid.The number of grains per fruit was significantly positively correlated with crude fat.The 1000-grain weight was significantly negatively correlated with crude fat and linolenic acid,and extremely significantly positively correlated with oleic acid.Oleic acid showed an extremely significant negative correlation with linolenic acid.Comprehensive analysis suggests that ZM materials can be used as intermediate materials to improve the related traits of flax.In this study,'Ya 2211','Ya 2202'and'Ya 2209',which performed well in terms of traits,can be used for further in-depth research to breed new high-yield and high-quality flax varieties.关键词
