What should I pay attention to when selecting excellent varieties of wheat? The improved wheat varieties are based on the genetic characteristics of the original parents and are selected under certain natural conditions and cultivation conditions. They have certain adaptability. Therefore, the growth of wheat depends on the climate, soil, soil fertility and planting system of the planting land. , the level of production and pests and diseases, etc., choose the most suitable seed planting. 1. According to the climatic conditions of the region, especially the temperature conditions, winter, semi-winter or spring varieties are used. Second, select the fine varieties according to the production level In the dry and thin land, the drought-tolerant and sorghum-tolerant varieties are selected; in the dry and fertile land with thick soil and high fertility, the drought-tolerant and fertility-resistant varieties are selected; in the high-yield fields with good fertilizer and water conditions, the fertilizer-resistant and lodging-resistant varieties with high yield potential are selected. Third, select good varieties according to different farming systems For example, wheat and cotton intercropping not only require wheat varieties to be suitable for late sowing and early maturity, but also shorten the symbiotic period of wheat and cotton. At the same time, the plants are required to be short and compact, so as to make full use of light energy and improve photosynthesis efficiency. 4. Selecting good varieties according to the characteristics of local natural disasters For example, where dry and hot winds are heavy, use wheat varieties with anti-premature aging and anti-green dryness; where rust infection is heavier, use varieties resistant to rust; in areas with heavy rain and severe waterlogging in the south, less sunshine, wheat spike differentiation It takes a long time, so it is necessary to use varieties that are resistant to (resistant) scab and long in dormancy. 5. Good grain quality and good quality It mainly includes good nutritional quality, processing quality in line with the requirements of finished products, full grain, high bulk density and high sales price. Sixth, the selection of good seeds must be tested and demonstrated In the production of wheat, it is necessary to continuously replace new varieties according to changes in production conditions and production, and to prevent large-scale introduction and frequent replacement of varieties without trial. At the same time as planting the main varieties of wheat that are mainly promoted in the local area, new varieties should be introduced for experimentation and demonstration, and the corresponding seed breeding work should be done to determine the “successful†varieties and maintain the high quality of the production seeds.
