一、应用高光效育种培育“媒介亲本”:将籼粳稻的优良性状融成一体的籼粳交,是培育出高产、优质、多抗新品种的重要途径之一。但籼粳交属于亚种间杂交,它们的当代难以稳定,不孕性很高。江苏省农科院遗传生理所研究员崔继林等,经多年高光效育种试验,新近已选育出一个特异的中粳株系“02428”(崇明汲滨稻株系x云南螃蟹谷)。用
I. Application of High Light Efficiency Breeding and Cultivation of “Medium Parents”: Indica / Japonica hybrids that integrate the fine traits of indica and japonica are one of the important ways to cultivate new varieties with high yield, high quality and multiple resistance. However, indica and japonica hybrids belong to the subspecies hybridization, they are difficult to stabilize the contemporary, high infertility. Cui Jilin, a researcher at the Institute of Genetics and Physiology, Jiangsu Academy of Agricultural Sciences, has developed a new japonica rice line “02428” (Chongming Jibin Rice Lines x Yunnan Crab Valley) recently after years of experiments on high light efficiency breeding. use
