Embodiment Construction

[0020] A. Breeding of sorghum varieties

[0021] (1) Parental selection for hybrid breeding: select Jinliang 9-2 as the female parent and Sorghum sorghum as the male parent for hybridization to obtain hybrids.

[0022] (2) Breeding of hybrid progeny: Plant the hybrid progeny, investigate the growth potential, growth speed, root system development, lodging resistance and maturity period of the hybrid progeny during the growth period, and select individual plants with excellent growth traits to harvest separately . After harvesting, threshing was carried out, and the threshing of sorghum ears with high single ear weight was weighed as sorghum seeds for comprehensive excellent traits.

[0023] (3) Enlarged propagation and purification and rejuvenation to obtain sorghum varieties with high-yield traits: the selected sorghum seeds with excellent traits and high-yield per ear traits are planted, and after the sorghum matures, the sorghum with large spikes and full grains is selecte...

Abstract

A selectively cultured high-quality sorghum whose grains contain low content of tannic acid and high content of protein, starch and trace elements is cultures through hybridization between Jingliang 9-2 as female parent and high-viscosity white sorghum as male parent and culturing generation by generation. Its planting method includes such steps as applying soil improver, applying base fertilizer, applying leaf fertilizer and post-maturation treating.

Description

technical field [0001] The invention proposes a high-quality sorghum variety breeding and its cultivation method in the field of agriculture. Background technique [0002] The original variety, sorghum, once dominated crop cultivars, but was replaced by hybrids due to low yields. Although hybrid sorghum varieties have high yields, they have poor taste and high tannin content, which has an astringent taste, which affects people's appetite. At the same time, eating sorghum rice with high tannin content can also cause gastrointestinal discomfort. Although the traditional variety of sorghum has good taste, its yield is low, its content of keratin protein is high, and its nutritional value is poor. As people are satisfied with high-calorie rice and white flour, the incidence of obesity and diabetes has gradually increased, and they are favoring traditional coarse grains, especially sorghum rice. According to relevant data records: every hectogram of sorghum rice contains 12.5g ...
