辽河流域平原水稻区是我省水稻的主产区,各育种单位如农民育种家选育了一批优良水稻品种,同时由国外引入了一些品种。但生产上哪个品种为主栽品种,仍没有定论。1990～1991年“辽河流域水稻高产高效益综合配套技术研究”协作组在辽河流域平原稻区9个点做了品种比较试验。现用灰色关联度分析方法对参试品种进行综合评估。目的在于定量地、客观地评定参试品种;为选出适于辽河流域平原稻区的主栽品种提供依据。
The plain rice area in Liaohe River Basin is the main rice producing area in our province. Breeding units such as farmer breeders have bred a group of excellent rice varieties, and introduced some varieties from abroad. However, the production of which varieties are mainly cultivars, is still inconclusive. 1990 ~ 1991 “Liaohe River Basin rice high yield and efficiency of integrated supporting technology” collaboration group in the Liaohe River Basin plain rice area 9 points to do a comparative test. Gray correlation analysis method is now used to conduct a comprehensive assessment of the varieties tested. The purpose is to quantitatively and objectively assess the tested varieties; provide the basis for selecting the main cultivars suitable for the plain rice area in the Liaohe River Basin.
