Liaofu 2006, a premium-quality hybrid japonica rice variety
Liaofu 2006 is a new disease-resistant hybrid japonica rice combination bred in recent years by the Rice Research Institute of the Liaoning Academy of Agricultural Sciences by crossing a high-quality male sterile line with a premium-quality restorer line; it offers high quality, high yield, high efficiency and wide ecological adaptability. In Shenyang its whole growth period is about 165 days, making it a mid-to-late maturing combination. Plant height is 110-120 cm and panicle length is 25-30 cm; at maturity the panicles hang below the leaves in a loose-panicle type. The stems have good elasticity, and the basal stem nodes are thick and short, giving strong lodging resistance; tillering ability is strong and the percentage of productive tillers is high, with the number of effective panicles per 667 sq m (1 mu) generally

Multiple high-yield, multi-resistant, high-quality hybrid japonica rice varieties successfully bred in Tianjin
After several years of research, the Rice Research Institute of the Tianjin Academy of Agricultural Sciences has successfully bred 9 new high-yield, multi-resistant, high-quality hybrid japonica rice varieties. At present, 6 of the new varieties have been designated as nationally approved high-quality hybrid japonica rice varieties, with an annual promotion area of more than 1 million mu, accounting for 20% of the total hybrid japonica rice area in China. It is understood that the Rice Research Institute of the Tianjin Academy of Agricultural Sciences, through independent innovation, successfully solved the worldwide problem of hybrid japonica rice breeding, and was the first in China to establish a hybrid japonica rice breeding technology system and seed production system, raising hybrid seed purity

Super hybrid japonica rice successfully bred in Tianjin
In the golden autumn season, the thousand-mu rice fields at the Ninghe Rice Original Seed Farm are a sea of gold, and the super hybrid japonica rice planted here - the high-quality Xiaozhan hybrid japonica rice - has been successfully harvested. This marks major progress in the Tianjin major science and technology project led by Academician Yuan Longping - "Research on New Combinations of High-Quality, Super-High-Yield Xiaozhan Rice." Based on analysis of the number of grains per rice ear and other factors, rice experts expect the yield per mu to reach 800 kg, an increase of more than 150 kg over conventional rice yields, with greatly improved quality. According to reports, the conventional rice varieties currently planted in North China

Variety Introduction of the New Japonica Hybrid Rice Combination Huayou No. 5
The new japonica hybrid rice combination Huayou No. 5 is a high-quality, high-yield, multi-resistant, early-maturing new combination developed by the Institute of Crop Cultivation of the Liaoning Academy of Agricultural Sciences. Yield comparison trials were completed from 1997 to 1998, and it entered the Liaoning Province hybrid rice regional trial in 1999. In the two-year yield comparison trials from 1997 to 1998, the yield per mu was 574.8-698.1 kg, an increase of 11.1-27.4% over the control Liaojing 454-17. 1. Growth characteristics: The growth period of this combination is 155 days, plant height 10

Important breakthrough made in hybrid japonica rice breeding
On the 18th, the reporter learned from the Shanghai Academy of Agricultural Sciences that agricultural scientists in Shanghai have made a breakthrough in hybrid japonica rice breeding in the Yangtze River Basin. Following the acquisition of the first hybrid late japonica rice restorer line in the Yangtze River Basin to obtain national plant variety protection rights, the first southern hybrid late japonica rice combination to pass national variety approval has also been bred. At present, a series of strongly heterotic combinations have become an important support for the "seed source" of hybrid japonica rice in the Yangtze River Basin. Researchers from the Crop Breeding Institute of the Shanghai Academy of Agricultural Sciences used intermediate materials between indica and japonica subspecies as "bridge parents"
