吉林省水稻品种系谱及遗传分析

STUDY ON GENEALOGY AND INHERITANCE OF THE IMPROVED RICE VARIETIES IN JILIN PROVINCE

本文对吉林省育成的40个水稻主要品种进行了系谱追溯及遗传分析。结果表明绝大多数育成品种系谱是与日本品种保持着极其密切的亲缘关系。可划分为“爱国”、“龟之尾”、“坊主”、“北海一号”、“旭”等五大衍生系统。细胞质主要来源于“东乡2号”、“关山稻”“丰稂”、“坊主”等4个日本原始亲源。细胞核主要来源于“龟之尾”、“爱国”、“东乡2号”、“坊主”、“关山稻”、“旭”、“庄内早生”等7个日本原始品种。为了提高品种增产潜力,必须从世界各地广泛搜集、引入各种新抗源和新基因类型。

Forty improved rice varieties developed in Jilin province were genealogized, and their inheritance were analysed in this text. The result showed that most of the improved rice varieties in Jilin province had a close blood relationship with Japanese varieties. They were divided into five derivative systems as Aikoku, Kame no o, Bozu. Hokai No. 1 and Asahi. The main sources of their cytoplasms originated from four Japanese ancestral varieties: Higashigo No. 2 Sekiyama ine, Hojo and Bozu. And the main sources of their cellnucleuses originated from seven Japanese ancestral varieties. Kame no o, Aikoku, Higashigo No. 2, Bozu, Sekiyama ine, Asahi and Shonai wase. In order to increase yield potency of the rice variety it is necessary to collect and introduce various new rice resistant sources and new rice genotypes widely in the world.
