2. Jiayifu Rice 1588 is highly resistant to rice koji disease, its grains are large and full, and it does not fall grains, which is convenient for mechanical harvesting. In the 2019 production test, the yield was increased compared with the control, and the main indicators of its rice quality also reached the national standard secondary rice standard.

For the northern region, due to its dry climate and lack of precipitation, it is necessary to choose upland rice varieties suitable for the ecological environment of the region when planting upland rice. After screening and comparison of upland rice varieties, the following are currently considered to be:

1.Longkou local excellent varieties of rice flowers. This is a traditional northern upland rice variety, which has the characteristics of high yield, strong drought tolerance and lodging resistance. Its rice is full of grains, soft in texture, and sweet in taste, and is one of the rice varieties favored by northerners.

2.Hunan Indica - Changxiangyou 17. Although the Hunan region does not belong to the north, this variety is suitable for cultivation in semi-arid areas, such as Shanxi, Hebei and other places.

It is one of the most popular upland rice varieties due to its good drought resistance, wide adaptability, high yield, and good rice quality.

3.Sichuan Indica - Ronghan No. 6. Although the climate in the Qinrandong area of Sichuan is humid, Ronghan No. 6 is also one of the upland rice varieties suitable for cultivation in the north.

It is not only adaptable and stress-resistant, but also has a high yield and high-quality rice quality, so it is loved by many growers.

In general, these upland rice varieties have the characteristics of conforming to the northern climate and ecological arid environment, and perform well and have excellent quality during planting and harvesting, and are also favored by many growers.

The selection of upland rice varieties planted in northern China should consider a variety of factors, such as drought degree, drought tolerance per mu of sparrow residue, yield, quality, etc. Here are a few upland rice varieties that are suitable for cultivation in the north:

Changza No. 1: This is a kind of upland rice variety with strong adaptability, strong drought tolerance and high yield, which is suitable for planting in arid areas in the north.

Xinfeng No. 6: This is an upland rice variety with strong adaptability, strong drought tolerance and good lodging resistance, which is suitable for planting in the arid areas of the north.

Youhan No. 1: This is a kind of upland rice variety with strong adaptability, strong drought tolerance, good lodging resistance and good quality, which is suitable for planting in arid areas in the north.

Japonica 3138: This is a variety of upland rice with strong adaptability, drought tolerance and high yield, which is suitable for planting in the arid areas of the northern forest.

It should be noted that the drought tolerance and adaptability of different varieties will vary depending on the climate, land and other conditions, and the specific variety selection needs to be adjusted according to the actual local situation. At the same time, when planting upland rice, it is also necessary to pay attention to reasonable fertilization and scientific management to improve yield and quality.

The name of the "High Temperature Resistant Super Rice" variety is "Ton Liangyou 900", which can also produce stably at 40 high temperatures.

Ton Liangyou 900' is based on the fourth super rice 'Y Liangyou 900', which was successfully bred by polymerizing African rice heat tolerance genes. Deng Qiyun introduced that when the heading and flowering period of other rice varieties that are not tolerant to high temperature encounters a temperature of more than 35, the yield may be reduced by one percent for every 1 high. In other words, if there is a high temperature of 38, the yield may be reduced by 30%.

The 'ton liangyou 900' is both high yield and stable yield, in high temperature, compared with other varieties of seed setting rate increased by more than 30%, in the extreme high temperature there is also a 55% seed setting rate, can reduce the impact of global warming on food security. ”

Deng Qiyun told reporters that the variety is completely in accordance with the requirements of industrialization to breed, last year's pass was as smooth as the national examination, this year has been trial, next year can be promoted in a large area. This variety has short stems and strong tillering power, which is suitable for light and simple cultivation and planting such as large-area mechanization, which can greatly save planting labor costs.

According to the virtual Qi, in mid-September this year, the Ministry of Agriculture and Rural Affairs organized an expert group to measure the yield of the new variety of "heat-resistant super rice", and the average yield per mu reached kilograms under the cultivation level of ordinary farmers, exceeding the average yield of 780 kilograms per mu of super rice recognized by the Ministry of Agriculture and Rural Affairs.

Ton Liangyou 900' coordinates the contradiction of high yield and high quality of super rice, high quality and low yield, not only high yield and stable yield, but also good rice quality! Deng Qiyun said that it introduces japonica rice bloodline through wide affinity gene bridging, aggregates high-quality genes, has a high rice yield, a whole rice rate, and a good taste of rice.
