对数千份云南稻种资源初步进行了农艺性状及抗性鉴定,云南稻种资源极其丰富多采,尤以大穗、大粒、优质资源居多,但其缺点亦很突出,如植林高、叶披散、易倒等。针对云南稻在江苏的利用问题开展了有关研究,利用云南稻培育出香血糯等名贵品种并用于生产。通过同工酶分析初步推论了云南稻在稻种起源进化上的地位。 Several thousand Yunnan rice germplasm resources were initially subjected to agronomic traits and resistance identification. Yunnan rice germplasm resources are extremely rich and diverse, especially large spikes, large grains, and high quality resources, but their disadvantages are also prominent, such as high plantation and leaf Phi, easy to fall and so on. Aiming at the problem of the utilization of Yunnan rice in Jiangsu, some researches have been carried out on the use of Yunnan rice to cultivate valuable varieties such as Xiangnuo glutinous rice and used for production. Based on the isozyme analysis, we initially deduced the status of Yunnan rice in the evolution of rice origin.
