Breakthrough in Japonica Hybrid Rice breeding
The reporter learned from the Shanghai Academy of Agricultural Sciences on the 18th that Shanghai agricultural scientists have made a breakthrough in the breeding of japonica hybrid rice in the Yangtze River Basin. After obtaining the first restorer line of hybrid late japonica rice in the Yangtze River basin which was granted the right of national protection of new plant varieties, the first southern hybrid late japonica rice combination approved by the national variety was bred. At present, a series of strong dominant combinations have become an important support for the "provenance" of japonica hybrid rice in the Yangtze River Basin. Researchers of the crop breeding Institute of Shanghai Academy of Agricultural Sciences used the intermediate materials of indica and japonica subspecies as "bridge parents".

The wheat harvest at the end of wax ripening is of high quality and high yield.
In recent years, researchers have studied the grain filling rate of many wheat varieties, and the 1000-grain weight is the maximum at the end of wheat wax ripening. After 3 days of harvest, the average daily weight per 1000-grain weight decreased by 0.3-9.4 g, while that per 1000-grain weight decreased by 1-1.2 g per day from the 4th to 5th day. If it is calculated according to 350000 ~ 400000 ears per mu and 35 grains per panicle, the yield will be reduced by 1315kg per mu when the 1000-grain weight is reduced by 1g. The results show that the harvest of wheat is the most suitable at the end of wax ripening, because the stems and leaves of wheat are in the milk stage.

Fine classification of wheat seedlings for skillful management of diseases
After the emergence of wheat seedlings, different types of weak seedlings are often formed due to the influence of natural conditions and cultivation measures. The prevention of weak seedlings and symptomatic management are introduced as follows: weak seedlings caused by soil drought mostly occur in wheat fields where soil moisture is insufficient or ventilated, which is characterized by slow tillering, gray-green leaves, short heart leaves, slow growth or stagnation (called by the masses as "shrinking seedlings"), yellow and dry leaves in the middle and lower parts, and few and thin roots. Key points of management: combined with watering, 15 kg ammonium bicarbonate per mu.
