Research and Application of Breeding Techniques of Special-early Maturing Early Rice Varieties
Double-cropping early rice is an important part of staple crop rice.In recent years,there were prominent problems,such as intensive crops rotation,prominent seasonal contradictions,frequent occurrence of natural disasters.There was an urgent need for new special-early matu-ring early rice in production.By collecting and identifying excellent special-early maturing germplasm resources,combining traditional breeding and molecular breeding techniques,we aimed to coordinate the relationship between early maturing and high yield,and comprehensively im-prove rice quality and resistance.A number of new special-early maturing early rice varieties were developed,such as Luzao 301,Luzao 302,Nanlingzao 3,Nanlingzao 4,and the growth period of them were more than 5 d earlier than the control.And the yield ability,disease resistance and rice quality were excellent.This research provided new ideas and impetus for the development of double-cropping early rice.
