我们发现粳稻分株苗比其实生苗生长茂盛,名之为分株优势。我们又发现分株繁殖的杂交粳稻具有协同优势,即是生长茂盛的指数超过杂种优势与分株优势之和。此种生产体系能使梗稻增产。我们认为采用这种体系可以缩短粳稻育种周期,并且不用种子而能栽培水稻。
We found that japonica rice seedlings grow more flourish than in fact, called the ramets advantage. We also found that japonica hybrids ramets have a synergistic advantage, that is, the index of flourishing growth exceeds that of heterosis and ramet. This production system can increase stem rice yield. We think this system can shorten the breeding cycle of japonica rice and grow rice without using seeds.
