“闵优128”是用“83A”与“128”配组而成的早熟、高产、优质杂交粳稻新组合,具有丰产性好、适应性广、抗逆性强的特点。1996～1997两年参加上海市杂交粳稻区试分别比对照“91-17”增8.7％和3.5％,两年均居参试品种首位。1996年参加南方杂粳区试比对照518kg,增产9.1％,显示出广泛的适应性和广阔的应用前景。1996年闵行七宝联明村制种149亩,平均亩产107kg,1997年北桥中心村等制种550亩,平均亩产145kg。现将“闵优128”高产制种技术综合如下。 Minyou 128 is a new combination of early maturing, high-yielding and high-quality japonica hybrid rice with “83A” and “128”. It has the characteristics of high yield, good adaptability and strong resistance. The hybrid rice japonica test in Shanghai from 1996 to 1997 increased by 8.7% and 3.5%, respectively, over the “91-17” in the control, ranking the first among the tested varieties for two years. Participate in southern hybrid japonica in 1996 than the control 518kg test, an increase of 9.1%, showing a wide range of adaptability and broad application prospects. In 1996, Minhang Qibao Lianming Village produced 149 mu with an average yield of 107 kg per mu. In 1997, Beiqiao Central Village produced 550 mu and the average mu yield was 145 kg. Now “Minyou 128” high-yielding seed production technology is as follows.
