籼、粳稻亚种间杂种优势利用,有助于提高水稻产量。中粳02428与广东目前栽培的6个早籼稻品种组配组合,杂种一代亲和性良好,生物产量优势显著,经济系数与亲本基本相同。认为可提供化杀杂交育种直接利用及亚种间杂交育种的中间材料。
Indica and Japonica subspecies heterosis utilization, help to improve rice yield. Chinese rice 02428 was combined with 6 indica rice cultivars currently cultivated in Guangdong. The hybrids had good affinity and significant biological yield advantage with economic coefficient basically the same as that of their parents. It is believed that it can provide the direct use of crossbreeding crossbreeding and the intermediate material for crossbreeding between subspecies.
