Optimal selection method for quality of sweet corn

Abstract

The invention relates to an optimal selection method for the quality of sweet corn. The method comprises the following steps of: sowing, testing seeds, tasting and selecting according to head progeny rows, and quickly breeding a sweet corn inbred line with thin skin, good mouthfeel and high yielding ability. The method is easy to grasp and has strong maneuverability; a quality optimization selection technology that selection of characters such as field investigation, fresh spike appearance, peculiar smell, color and luster, skin thickness and the like is combined with skin, sweetness, glutinousness, fragrance and comprehensive character scoring identification after indoor cooking is adopted; and a plurality of elements such as color change of fresh spikes after cooking, quality guarantee period, scoring of professional researchers and ordinary crowds and the like are comprehensively considered, a sufficient reference evidence is provided for special corn breeding, and the method is favorable for quickly identifying and selecting novel materials with good mouthfeel and high quality.

Description

technical field [0001] The invention relates to the field of grain quality, in particular to a method for optimizing and selecting sweet corn quality. Background technique [0002] With its rich nutrition, sweetness, stickiness, tenderness and aroma, sweet corn has great development potential in foreign markets, and can be further processed to appreciate. Its planting benefits are 2 to 4 times that of ordinary corn, and its economic benefits are significant. For example, the added value of sweet corn in the United States can reach 300-400%, and the added value of conversion is higher. In our country, with the improvement of people's living standards, the dietary structure is changing from subsistence to nutrition and health, and the sweet corn industry is more and more favored by people. Due to the particularity of use, the sweet corn market has extremely high quality requirements, not only requiring high nutritional value, but also requiring thin skin, less slag, good tast...

Problems solved by technology

After the Ministry of Agriculture promulgated the sweet corn industry standard (NY / T523-2002), the standard evaluation method began to be widely used in the regional trials of fresh corn varieties in my country. The scoring standards are complicated and rarely used in actual breeding.

Therefore, sweet corn breeding only relies on the quality results of crude fat, crude starch, lysine, soluble total sugar, amylopectin and other content testing by industry standards and quality testing departments, and it is difficult to breed high-quality corn that meets the market requirements of special corn. variety, and the cost of testing is high, a large amount of samples is required, and there is a lot of waste of breeding materials
