The results showed that the practice of SSCMTS in hybrid rice could not only increase grain yield but also save seeds and labor. It was a new high-yielding way for the late transplanting seedlings and heavy panicle type hybrid rice cultivars to further utilize the high-yielding potential of hybrid rice cultivars. The increasing number of spikelets and ideal grain -filling were the direct factors for the high yield of SSCMTS in hybrid rice, and those high-yielding factors relied on high quality seedlings, sturdy individuals, high quality population and vigorous later growth.展开更多
