水稻重点不育系和父本主要农艺性状表现及相关性分析
Performance and Correlation Analysis of Major Agronomic Traits of Key Sterile Lines and Paternal Parents
摘要
Abstract
Grain weight and grain number per panicle are important and stable genetic yield components of rice.It has great significance to in-crease the genetic distance and enhance heterosis of hybrid rice by using rice parents with large grain weight and high seed setting rate in the current era of"simiao"rice,so as to improve the yield of hybrid rice and maintain a certain quality.This paper proposed the main agronomic traits breeding indexes of medium indica hybrid rice,and evaluated the key sterile lines and paternal parents tested by analyzing the perform-ance,variation and correlation of the main agronomic traits of the sterile lines and paternal parents tested.This work provided a reference for fur-ther breeding of these sterile lines and paternal lines and high-yield hybrid rice varieties.关键词
