Intercropping insect-resistant cotton with potatoes: both crops can achieve high yields
In recent years, the model of intercropping potatoes with insect-resistant cotton has been welcomed by the people. According to surveys, this model not only enables cotton to achieve high yields (lint yield of 90-100 kg per mu), but also "freely" yields an extra 1500-2000 kg of potatoes per mu. The key cultivation techniques are as follows. I. Potatoes ① Seed selection and sprouting. It is advisable to choose early-maturing, short-stalked, high-yielding virus-free varieties, such as Holland No. 7, Jinyin No. 8, etc., using 80-90 kg of seed potatoes per mu. In mid-February, cut the seed potatoes into pieces (each kg cut into 40-50 pieces) and use a sunny cold frame or greenhouse

Rice cancer has met its nemesis: breeding of a disease-resistant new variety succeeds
Since the beginning of this century, rice stripe virus disease has continued to break out over large areas, in severe cases even causing rice farmers to lose their entire harvest. Rice stripe virus disease has been regarded as the "cancer" of rice. "Wuyujing 3", long recognized by the market as the main rice variety with the best taste and quality in Jiangsu Province and surrounding areas, has seen its planting area plummet in recent years because it is highly susceptible to rice stripe virus disease. Some stripe virus-resistant varieties either have shortcomings in yield and yield stability, or have not been fully recognized by the market for their rice quality. Rice farmers

How was the disease-resistant, fragrant and soft rice variety Jiuqi Xiang No. 1 bred?
I. Breeding process 1. Parent selection The internationally renowned rice variety Basmati, a superior rare fragrant-soft line obtained by mutation of Basmati original seed through solar radiation at this institute, and Xiangsimiao No. 2 were mixed and used as the male parent, with the conventional short-stalked, high-yielding, good-resistance and widely adaptable Qingzhen No. 8 as the female parent. 2. Progeny selection After a single plant was selected in the late season of 1991, various types of single panicles with medium-short stalks and plant-grain type similar to Xiangsimiao were selected respectively from the segregating materials of the F2 and F3 generations, then multi-generation selection and propagation and single-plant line comparative trials were carried out.

Insect-resistant potato bred first by Belarusian scientists
Scientists from the National Academy of Sciences of Belarus have announced a new research achievement: they have bred the world's first potato that can automatically kill pests. According to a report by Russia's Interfax news agency on August 7, to date, a pest known by the scientific name Colorado potato beetle has been the biggest headache for farmers, because it destroys large areas of potato fields every year and causes huge economic losses to agriculture. A new type of genetically modified potato recently bred by Belarusian scientists can specifically poison this beetle to death. A

New disease-resistant, high-yield rice variety launched by Bayer CropScience
On May 14, 2008, Bayer CropScience announced the launch in India of ArizeRDhani, the world's first hybrid rice variety resistant to bacterial leaf blight. Compared with conventional varieties, this new variety can increase yields by 20%-30% and provides the crop with strong protection against the highly destructive bacterial leaf blight. "Rice is a staple food in many developing countries and emerging markets. Although global demand for this crop continues to grow, the occurrence of diseases can greatly affect harvests and threaten food supply.

New high-yield and disease-resistant cotton variety Sumian 14
This variety has high yield. In the 1996-1997 provincial regional trial, the lint yield was 96.12 kg per mu, 5.36% higher than the control Simian 3, reaching an extremely significant level. In the 1997-1998 national regional trial, it yielded 11.6% more than Zhongmiansuo 12, and in 1998-1999 the high-yield plot reached 140-160 kg. It has strong disease resistance, is highly resistant to fusarium wilt with a disease index of 1.48, and resistant to verticillium wilt with a disease index of 11.54. It has excellent quality: 2.5% span length 29 mm, specific strength 23.6 g/tex, micronaire value 4.5

New Cotton Variety 2019: High-Yield, Insect-Resistant Seeds Bred in Anhui
The Cotton Research Institute of the Chinese Academy of Agricultural Sciences recently bred a new cotton variety (Zhongmiansuo 53) in Hefei that can increase yield by 20%. A single cotton plant can bear more than 50 bolls, and the seed cotton yield per mu can reach 751 jin, which is twice that of ordinary cotton, and it has stronger insect resistance. At present, Zhongmiansuo 53 has been listed as a subsidized variety for the promotion of improved cotton varieties in Anhui Province in 2007. At the same time, Zhongmiansuo 53 is also a dual-gene transgenic insect-resistant cotton.
