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粳籼交,是培育出高产、优质、多抗新品种的重要途径之一。江苏农科院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”。用它作亲本同籼稻或粳稻杂交,杂种一代均能表现高度的亲和性、高结实率和杂种优势。其穗长可达30厘米,穗粒200多粒。该院已获得许多有希望的优良育种材料。
I. Application of high light efficiency breeding to cultivate “medium parents”: One of the important ways to breed new varieties of high yield, high quality and multi-resistance is to combine japonica indica with the fine traits of indica and japonica. Jiangsu Academy of Agricultural Sciences after years of high light efficiency breeding trials, recently has bred a specific japonica rice “02428.” It is used as a cross with indica or japonica parents, and the hybrid generation can show high affinity, high seed setting rate and heterosis. Its spike length up to 30 cm, more than 200 grains per spike. The hospital has received many promising fine breeding materials.
