AI Technical Summary

Benefits of technology

In summary, it describes how different types of rice have been used together during breeding or crossing over between them. These combinations help create better qualities that are more durable than other forms such as sorghum (a type called corn), wheat, barley, rye) but also provide higher yields when combined into new crops like pulsiveweeds. Additionally, they may improve certain characteristics related to their cultivation practicality without causing harmful side reactions on plants grown therefrom. Overall, these techniques aim towards improving crop production efficiency and productivity.

Problems solved by technology

This patents discusses how dried rice plants grow better than other types of vegetables due to its ability to absorb moisture without losing their shape when exposed during periods of drought stress. However, current methods used to increase soil fertility often result in decreased root growth capacity and reduced yields. To address this issue, various techniques like genetic modification and molecular biology may help creation of novel sources that could provide higher levels of nitrogen availability while maintaining good health properties over time.

Abstract

The invention discloses a breeding method of a high-resistance black millet variety and belongs to the technical field of millet resistance breeding. A black millet variety, a drought-resistant variety, a millet blast-resistant variety, a poliosis-resistant variety, a kernel smut-resistant variety, a herbicide resistance variety and a rust disease-resistant variety are taken as parents, and the black millet variety which is black-seed in grain character, drought-resistant and herbicide-resistant and is capable of resisting multiple diseases is bred through hybridization, multiple-crossing polymerization, multi-generation resistance identification and seed coat color, agriculture and yield character screening. The variety is good in quality, good in resistance and high in yield, the usage amount of a pesticide can be reduced by planting the variety, the labor is reduced, the environmental pollution is reduced while the yield is improved, and the rural income is increased.
