D297优63(D297用农业大学选育的D297不育系与明恢63配组而成的晚稻杂交组合。1989年我场从福建省尤溪县管前乡引入试种,用8个晚杂组合进行评比,以汕优63为对照,试验后经方差分析,D297优63组合产量最佳,单产比对照增产48.7公斤,增产率为12.2％,达显著水平。 同时在试验期间,经移栽后一星期的(7月1日至7月6日)124小时的长时间洪水淹没,结果产量仍居第一位,受淹后返青快,容易恢复生机,抗洪耐涝能力强。
D297 You 63 (D297, D297, a combination of D297 and Minghui63, bred by Agricultural University, was introduced in 1989. The experiment was conducted in Guanqian Township, Youxi County, Fujian Province in 1989, The results of variance analysis showed that the yield of the combination of D297 and You 63 was the best, yield increased by 48.7 kg and the rate of increase was 12.2% compared with the control, reaching a significant level.At the same time, After a long period of 124 hours of inundation in the last week (July 1 to July 6), the floodwaters continued to flood for a long time. As a result, the output remained the first place, returning to green soon after flooding, easing its resurgence of vigor and resisting floods and waterlogging.
