“8优161”是上海市农科院用“8204A/R161”育成的杂交晚粳新品种,我市1995年引进,表现品质优、产量高。桐乡市1997年种植656.8hm~2,产量9313.5kg/hm~2,比常规稻增产12.6％;1998年种植1533.3hm~2,产量9439.5kg/hm~2,比常规稻增产14.19％。桐乡市梧桐镇1998年“8优161”309.1hm~2,产量9109.0kg/hm~2,比常规稻增11.9％。该品种与常规稻有不同生育特性,必须因种栽培才能获得高产。为此,我们对该品种近几年来的试验、示范进行专题总结。 “8 You 161” is a new hybrid japonica variety bred by Shanghai Academy of Agricultural Sciences with “8204A / R161”. It was introduced in 1995 and has excellent quality and high yield. Tongxiang City in 1997 planted 656.8hm ~ 2, yield 9313.5kg / hm ~ 2, 12.6% higher than conventional rice production; 1998 planted 1533.3hm ~ 2, the yield 9439.5kg / hm ~ 2, 14.19% increase over conventional rice. Wutong Town, Tongxiang City, 1998 “8 You 161” 309.1hm ~ 2, yield 9109.0kg / hm ~ 2, 11.9% increase over conventional rice. The variety and conventional rice have different reproductive characteristics, must be cultivated for high yield. To this end, we conducted a special summary of the experiment and demonstration of the variety in recent years.
