High-yielding cultivation techniques of Rice "Hybrid glutinous intercropping"
Rice "hybrid glutinous interplanting" refers to the intercropping and cultivation of hybrid rice and glutinous rice. That is, medium-culm hybrid rice and high-culm glutinous rice, making use of the wide row advantage of hybrid rice in wide and narrow rows, increase the planting mode of single-row glutinous rice according to a certain band width, row ratio and width. 1. The main advantages of hybrid waxy intercropping technology 1. Increase rice yield: the results showed that the total yield of hybrid waxy intercropping was 28 kg higher than that of ordinary hybrid rice per 667 square meters and 110 kg higher than that of conventional glutinous rice. 2. Increase income: glutinous rice ratio

Population selection should be paid attention to in efficient goose breeding.
Population is the abbreviation of a species group such as group, strain, variety or genus. Population selection is based on the fact that both parties belong to the same or different populations. Population selection can be divided into two categories: purebred breeding and cross breeding, while hybrid breeding can

How about hybrid seeds? What does open pollination mean? the difference between hybrids and open pollination
There are three kinds of seeds: hybrid, open pollination and family heirloom. Stark Bros only carries non-GM heirloom seeds, all of which are open pollinated. The following are definitions and examples of each seed type to eliminate the common confusion surrounding them. Hybrid

Seed production techniques of Cotton male sterile Lines
The technology of cotton male sterile line seed production uses insect-assisted pollination male sterile line hybrid seed production method, which overcomes the shortcomings of artificial de-pollination hybrid seed production method, which is widely used at present, such as time-consuming and labor-consuming, high intensity of work, complex management of seed production field and high cost of seed production. The labor consumption can be reduced by more than 50%, and the purity of hybrid seeds can be further improved. It is the most ideal way to produce cotton hybrid seeds. The seed production technique of cotton male sterile line is to cultivate recessive low phenol markers.

Tianjin successfully bred several new japonica hybrid rice varieties with high yield, multi-resistance and high quality
After several years of research, the Rice Research Institute of Tianjin Academy of Agricultural Sciences has successfully selected 9 new japonica hybrid rice varieties with high yield, multi-resistance and high quality. At present, six new varieties have been identified as high-quality hybrid japonica varieties, with an annual extension area of more than 1 million mu, accounting for 20% of the total area of hybrid japonica rice in the country. It is understood that the Rice Research Institute of Tianjin Academy of Agricultural Sciences innovated independently and successfully solved the worldwide problem of hybrid japonica rice breeding, and took the lead in building a hybrid japonica rice breeding technology system and seed production system in China to improve the purity of hybrids.

7 to distinguish between true and false hybrid rice seeds
Look at the neatness. The seed shape of hybrid rice mixed with other rice is irregular. The seeds of male parents or other indica rice were slender and fuller than those of hybrid rice, while japonica rice was more round. Second, look at the husk color. There are slightly uneven yellowish brown on the husk of hybrid rice seeds.

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".
