近代水稻育种史证明,以矮秆、高收获指数为主要特征的新株型,导致了稻谷产量的显著增长。我们在粳稻矮化育种中,曾利用云南稻种“雪河矮早” (粳型)作为矮源亲本,发现其后代株高表现特异。现将有关研究资料整理如下。
The history of modern rice breeding proves that the new plant type with dwarf and high harvest index as its main features has led to a significant increase of paddy output. In the dwarf breeding of japonica rice, we used the Yunnan rice variety “Xuehe Aizao” (japonica) as the dwarf source parent and found that the offspring plant height was specific. The relevant research data are now organized as follows.
