为探究早籼稻珍汕97 B改良新不育系的配合力和稻米品质，以珍汕97 A为对照，利用珍汕97 B改良的6个不育系，与7个早杂恢复系按照NCⅡ遗传设计配制成49个杂交组合。结果表明，新改良不育系及其配制组合的产量和品质性状配合力比珍汕97 A有明显改善。其中，不育系珍品A分别在产量、总粒数和结实粒数上一般配合力效应最好，品质性状较好，在育种上有较好的利用价值。

In order to explore the combining ability and quality of the newly developed cytoplasmic male sterile (CMS) lines from Zhenshan 97B in indica rice (Oryza sativa L.), 49 crosses were made according to NC Ⅱgenetic design by using the six newly developed CMS lines ( with Zhenshan 97A as reference ) as female parents and seven early-maturity restorer lines as male parents .The results showed that the combining ability of yield and quality of the newly developed CMS lines was improved significantly compared with Zhenshan 97A.Among the CMS lines, Zhenpin A had the highest general combining ability ( GCA) of yield, spikelets per panicle and filled grains per panicle, possessed pretty good quality , and showed high rice breeding value .
