利用常规优质稻黄华占创制高抗、高产新种质

    Creation of New Germplasm with High Resistance and High Yield by Using the Conventional High-quality Rice Huanghuazhan

    • 摘要: 黄华占是来自中国南方的一种广泛适应的香稻(籼稻)常规稻品种,具有高产优质的特征。自2006年由广东省农业科学院育成以来,广泛种植于浙江、广东、广西中部和南部、湖南山丘区等省(区)。生产实践表明,黄华占对稻瘟病抗性较差,在病害发生严重区域种植有一定的生产隐患。为利用黄华占创新种质,以其为育种亲本,通过与市场上主推的9份高产高抗杂交水稻品种杂交,利用常规育种及抗性筛选等手段,从中筛选出21份产量较高、抗性较好和垩白度有所改良的材料,可以作为优质种质在福建省早、中稻种植中加以利用。

       

      Abstract: Huanghuazhan is a a widely adaptable fragrant rice (indica rice) conventional rice variety from southern China, which has the characteristics of high yield and high quality. Since it was bred by Guangdong Academy of Agricultural Sciences in 2006, it has been widely planted in the provinces (regions) such as Zhejiang, Guangdong, central and southern Guangxi, and hilly regions in Hunan. The production practice showed that Huanghuazhan had poor resistance to rice blast, and there were some production hidden dangers when it was planted in the areas where diseases occurred seriously. In order to utilize the innovative germplasm of Huanghuazhan, it was used as the breeding parent to hybridize with 9 high-yield and high-resistance hybrid rice varieties which were mainly promoted on the market. Then, through the conventional breeding and resistance screening methods, twenty-one materials with high yield, good resistance and improved chalkiness degree were screened out, which could be used as the high-quality germplasm for the early-mature rice and middle-season rice planting in Fujian Province.
