Abstract

The rice dominant early-maturing gene Ef-cd and its application relate to a rice gene Ef-cd and its application. The object of the present invention is to provide a rice dominant early-maturing gene Ef-cd and its application, which is used to promote rice early-maturing without affecting yield, thereby further improving hybrid rice yield and adapting to short growth period conditions in high latitude regions. The nucleotide sequence of the rice dominant early maturing gene Ef-cd is shown in SEQ ID NO: 1 in the sequence listing. Application of rice dominant early maturing gene Ef‑cd in promoting early maturation of plants. The Ef-cd mutant of the present invention can be used to promote early maturation of rice without affecting the yield, thereby further improving the yield of hybrid rice and adapting to the short growth period conditions in high latitude regions, while also meeting the early maturation characteristics required by modern light and simple cultivation.

Description

technical field

[0001] The invention relates to a rice gene Ef-cd and its application. Background technique

[0002] Rice (Oryza sativa L.) is an important food crop for human beings, and more than half of the world's population uses rice as a staple food. China is a big rice producing country in the world and has an ancient history of rice cultivation. It is one of the largest rice production bases, and its total rice output ranks first in the world. In recent years, with the growth of the world population, the intensification of aging, the acceleration of urbanization, and the emergence of problems such as the destruction of vegetation in some areas and the deterioration of the environment, how to increase the yield and quality of rice under the condition of limited human and environmental resources Quality and ensuring food safety have become major issues related to the national economy and people's livelihood.
