Re: what was Yuan Longping's two small targets before 2020?

At present, the research on rice breeding in China has made some progress. For example, the Qingdao sea Rice Research Center has made several breakthroughs in several areas. Last September, at the central planting base, 4 materials with salt water and more than 6 per thousand salt were used for direct irrigation. In the evaluation of the authoritative results of small area planting, 300 kilograms per mu yield was exceeded and the highest yield per mu reached 620.95 kg.

this year, the center will also make 176 newly cultivated sea water rice materials before May 10th, in the northeast of China in the saline alkali soil, the arid and semi-arid areas of Xinjiang, the the Yellow River Delta in Dongying, and the city of Qingdao. In the 5 representative saline alkali land such as coastal saline alkali land, more than 20 test points were planted to observe their agronomic traits, rice yield and quality under different climate and soil conditions.

"we hope to obtain several kinds of potential high-yielding marine rice materials." Zhang Guodong said. At the same time, he said that the resources of salt and alkali resistance genes in China are still relatively few, and we expect to introduce some wild rice germplasm resources from abroad as soon as possible. "Lack of complete molecular markers for salt tolerance genes is also" hard ". Establishing accurate identification system of salt tolerance gene molecular markers can accelerate the breeding process effectively.
