两系杂交稻紫两优737功能成分与产量性状分析

Functional Components and Yield Traits of Two-line Hybrid Rice Ziliangyou 737

【目的】明晰紫两优737的功能成分含量及其与亲本之间产量的相关性状,为产品的进一步开发提供依据,【方法】以紫392S、福恢737和紫两优737以及白米对照宜优673,黑米对照墨江紫米为材料,比较了紫两优737及其亲本的功能成分和产量相关农艺性状的差异。【结果】紫两优737富含花色苷等抗氧化成分以及人体所需的关键氨基酸和矿质元素等功能成分,其抗氧化能力相关性状的遗传特点是以加性效应为主,F1代的表型值偏向低值亲本;紫两优737的产量相关性状表现了较强的杂种优势。【结论】紫糯杂交稻紫两优737富含多种功能成分,对紫两优737功能成分及其产量性状的综合评估为今后提升两系紫糯杂交稻的育种水平提供了参考依据。

【Objective】Functional components and yield-related traits of Ziliangyou 737 and its parents were determined.【Method】Functional components and yield-related agronomic traits of Ziliangyou 737 were compared with those of Zi 392S,Fuhui 737,the white rice control Yiyou 673,and the black rice control Mojiangzimi.【Result】Ziliangyou 737 was rich in antioxidants(e.g.,anthocyanins)and functional ingredients(e.g.,essential amino acids and minerals)carrying mostly additive genetic characteristics relating to antioxidant capacity and phenotypes of F1 generation biased towards low-value parents.A strong heterosis of the cross breeding was evident by the upgraded yield-related traits of Ziliangyou 737.【Conclusion】Rich in antioxidants and functional components,the purple glutinous hybrid rice Ziliangyou 737 was also high on the traits related to crop yield.This study illustrated a promising direction for breeding specialty rice varieties.
