从研究作物F_1代的优势和显性程度、亲子相关、配合力入手,探索其遗传规律,应用于育种实践,国内六十年代以来在小麦上的研究较多,近年来已用于水稻育种,但应用于杂交水稻三系选育的不多.且由于材料、方法、地区的不同,结果有异.为立足本地区粳三系的选育,需探明粳型杂种在本地的优势和显性程度,并通过亲子相关和配

From the study of F_1 generation’s dominant and dominant degree, parent-child relationship and combining ability, the genetic law was explored and applied to breeding practice. There have been many studies on wheat since the 1960s in China. In recent years, it has been used in rice breeding, However, the application of three lines in hybrid rice breeding is not much, and because of different materials, methods and regions, the results are different.In order to base on the japonica three lines in this region, the need to identify the advantages of japonica hybrids in the local and significant Sexuality, and through parent-child related and with
