Abstract:

The backcross progenies of ‘Hui 7954’ and ‘Shuhui 527’ were radiated with 300Gy 60Co γ ray, after multi-generation breeding, the new excellent hybrid rice unit ‘Nongfengyou 2008’ was cultivated. It took part in Quzhou region and production test in 2007-2008, later on registered as ‘Nongfengyou 2008’ by Zhejiang crop register committee in 2009. In regional test and production test, it all displayed strong hybrid vigor, moderate mature period, high yield, good quality, strong resistance of disease and other qualities, with great potential to increase yield. Since passed Zhejiang Province’s cultivar approval in 2009, its promotion area has been larger and larger, owning a booming application prospect. In order to provide technical support on promotion and cultivation of ‘Nongfengyou 2008’ in large area, this article summarized systematically its research process, variety characteristics and cultivation techniques.
