Breeding and application of the first class quality hybrid rice variety Baiyou 838
摘要
Abstract
[Objective]Development of a new rice variety in order to meet the demand of rice consumption and to getthe fine quality hybrid Simiao rice type for the rice region of South China. [Method]The new rice combination was developedby crossing sterile line Bai A with the restorer line Fuhui 838, and was tested in the regional trials, field tests and multi-point trial planting. The agronomic traits and quality characteristics have been investigated. The article also describedbreeding progress, characteristics, cultivation and seed production techniques of Baiyou 838, the differences between Bai Aand Fuhui 838 and its possible cause were also be described. [Result]The new weak photosensitive hybrid rice variety wasnamed as Baiyou 838 and registered. The newly developed dwarf variety showed strong tillering, lodging resistance, biggerpanicle size with more number of grains, good grain quality and color at maturity, etc. The main indices of rice qualitycharacteristics, such as brown rice rate, head rice rate and chalky rice rate were recorded as 81.78, 68.5 and 6.0％,respectively. Besides these characteristics, it showed 0.6％ chalkiness degree, grade 1 transparency, 5.7 alkali spreaaingvalue, 80 mm of gel consistency and 17.6％ amylose content. And Baiyou 838 attained the first class level of the nationalrice quality standard.关键词
