Exploration and Innovation of Distant Hybridization Germplasm of Spartina anglica, Soughum bicolor and Oryza sativa
摘要
Abstract
This study aimed to explore the germplasm resources of salt-tolerant Spartina anglica, sweet-stalk Soughum bicolor and high-yield Oryza sativa for innovation of new germplasms of salt-tolerant and sweet-stalk Oryza saliva with dual purpose of food and forage in Tideland. [Method] From 2009 to 2012, researches on distant hybridization of Spartina anglica, Soughum bicolor and Oryza sativa had been carried out, and the RAPD molecular identification of obtained distant hybridization materials had been conducted. [Result] Experimental evidences of hybrid seed set, transplanting and economic characters of hybrid materials were obtained; among the 14 hybrid materials for RAPD analysis, 5 materials shared common bands with Spartina anglica and Soughum bicolor parents, which were absent in Oryza sativa parent, indicating that the genetic component of Spartina anglica and Soughum bicolor parents has been integrated into the 5 distant hybrids. [ Conclusion] This study has important scientific significance in recourse utilization, agricultural efficiency improvement, food security, and cultivation strategy of China, showing broat pplication prospects.关键词
