| 摘 要： | 长江流域杂交早稻比例偏低,主要原因是现有审定推广的杂交早稻组合生育期偏长、食用品质较差及种子生产成本较高.认为发展两系杂交早稻,在早熟基础上求高产,向储备粮、饲料粮及工业用粮方向发展,有利于扩大杂交早稻的面积及比例.

| Abstract: | The lower proportion of early hybrid rice to total early rice in Yangtze River Valley was mainly because the existing widely-used early hybrid rice combinations had a longer growth duration, poorer eating quality and higher seed cost. It was thought to be favourable to increase the area and proportion of early hybrid rice by developing two-line early hybrid rice, pursuing high yield on the basis of early maturity and changing the usage of grains from food to reserves, feed and industry. |
