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

  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.
