北方大穗型超级杂交粳稻形态育种初探

A Preliminary Study on Morphologic Breeding of Northern Large-Panicle Type Super Japonica Hybrid Rice

针对辽宁省及北方粳稻产量现状 ,提出培育在较低群体下的高成穗率、高结实率、高灌浆速率的大穗型超级杂交经稻的育种思路 。

In view of the current situation in grain yield of japonica rice in Liaoning Province and north China,the authors proposed the idea to develop large panicle type super japonica hybrid rice with high panicle bearing tiller rate, high seed set and high grain filling rate under a relatively low population. The specific morphologic character indexes for F 1 hybrids and their parents were put forward and discussed in the paper.
