Problems solved by technology

However, the growth period of "Boshan" variety is as long as 180 days, the plant height is 140 cm, the yield is average, and the average number of grains per panicle is 80 grains, so it is difficult to be directly applied, and it is easy to lodging in production, and the production efficiency is low.

Abstract

The invention relates to a breeding method for an aromatic conventional rice variety with high head rice rate and excellently-slender rice grains and belongs to the technical field of genetic breeding of crops. By using the method, the aromatic long-grain rice variety which is moderate in growth period, shortened in plant, good in rice quality and excellently-slender in rice grains is created on the premise of breeding a variety keeping the high head rice rate and rice cooking characteristic of the original variety by genetic improvement according to excellent characteristics that a Burma specific variety is good in resistance, short and round in rice grains and high in head rice rate, and the rice grains are good in longitudinal ductility, high in length-to-width ratio, slender in shape and good in taste and mouthfeel after being cooked.

Description

technical field [0001] The invention specifically relates to a method for breeding a fragrant conventional rice variety with a high rice rate and extra slender rice grains, and belongs to the technical field of crop genetics and breeding. Background technique [0002] Rice is the main food crop in my country. my country is a major rice producing country. With the improvement of people's living standards, the structure of healthy diet and high-nutrition food has also changed. The quality of rice in my country is increasingly unsuitable for the needs of modern urban populations. How to improve the quality of rice is the focus of current rice genetics and breeding. The Myanmar "Boshan" variety has been cultivated in Myanmar for more than 130 years. It has been cultivated from southern to northern Myanmar. It has a wide distribution range, good adaptability, good resistance, and a large planting area. "Boshan" rice grains are short and round (the length of the rice grain is 6....
