用福建省三明市农科所选育的强恢复系明诙63所配制的杂交稻组合,优势都很强,各地均有种植。1986年全国推广面积已达4060万亩,但对不同组合各地反映并不一致。为了筛选适合我区栽培的二晚组合,特搜集我区大面积推广的四个组合汕优63、威优63、红优63、协优63,设M112为对照,进行比较鉴定。1986年按我区地域分南、北、中三个点,在黎川县良种场、地区农科所、南城县农科所进行。位置为北纬26°59’～27°59’,东经116°17’～116°50’,海拔50～100m。试验按正规区试方案进行,小区面积0.02亩,重复三次,统一于6月15、16日
The hybrid rice combination prepared by Minghui63, a strong restorer line selected by Sanming Agricultural Science Institute in Fujian Province, has strong advantages and is planted everywhere. In 1986, the nationwide promotion area reached 40.6 million mu, but it was not consistent with the different combinations. In order to screen the suitable two-night combination for cultivation in our district, we collected four combinations of Shanyou 63, Weiyou 63, Hongyou 63, Xieyou 63, and M112 for the large-scale popularization in our district for comparison and identification. In 1986, according to the geographical area of our region, the three points of south, north and middle were carried out in the breeding farm of Lichuan County, the regional agricultural science institutes and the agricultural institute of Nancheng County. The location is latitude 26 ° 59 ’~ 27 ° 59’ north, longitude 116 ° 17 ’~ 116 ° 50’ east and elevation 50 ~ 100m. Test according to the formal test area plan, the plot area of 0.02 acres, repeated three times, unified in June 15, 16
