Once transferred to the target gene, After all the work of all technical operations by conventional breeding, and then there is no other way.
do not want to tout the marvelous transgenic breeding, transgenic breeding of food security can not become a straw! !
make conventional breeding are the most important! ! ! ! !
by conventional breeding techniques can also solve the corn insect and herbicide resistance problems. The key now is our breeding methods, techniques, equipment, and so too primitive, too far behind, and how to change, how to quickly raise the hope that leaders at all levels should pay great attention! ! !
guaranteed as long as research funding, coupled with policy support and defend the law, breeding with the Chinese people's wisdom, the country's food security,UGG boots clearance, there is absolutely no problem!
Xianyu335 not genetically modified varieties, wide adaptability, high yield, good quality, people recognized.
hope that our friends express opinions!
transfer: the development of transgenic breeding should not ignore the conventional breeding
Beijing Agricultural Association strongly supports the development of the current state of transgenic breeding, which is one of the world's breeding industry trend is undoubtedly necessary and correct. But look at home and abroad, whether developed or developing countries, using various types of agricultural production is more than 99% improved varieties are the results of conventional breeding. Yuan Longping (rice breeding), Li ZS Academy (Wheat Breeding), Fang Zhiyuan Academy of Sciences (Gan Lanyu species), Academician Feng Hou (cucumber breeding), Cheng and academicians (wheat breeding), others, such as Li Denghai (maize breeding), Xie Hua (rice breeding) and many other breeders, they are in conventional breeding has made an outstanding contribution, the country has created enormous material wealth, well-known scholars. That or simply ignorance. First, the advantages of conventional breeding and the important value of the so-called conventional breeding
is selected in the sexual hybridization between parents breeding. Darwin called artificial selection. The founder of modern genetics,UGG boots, Gregor Mendel and genetic variation of the law, did the number of sophisticated analysis, invented the three laws of genetics, the separation of law, independent distribution law and the linkage and exchange law. What we call conventional breeding (all types of cross breeding) are essentially the three laws of building under the guidance of new varieties of practice. Human practice in the conventional breeding continuously enrich and develop its scientific content, such as the hybrid varieties, interspecific hybridization, hybrid, three-line hybrid and so on. On agricultural production, the creation and application of new varieties is to promote the development of core technologies of agricultural production. The exclusion of conventional breeding core technologies of modern agricultural scientific point of view, is clearly unscientific, scientific and technological progress in agriculture is also very harmful.
conventional breeding, the key is to determine the breeding objectives, how to achieve breeding goals selected parents, this is a very complex task, there is a very careful breeding theory. Jilin Academy of Agricultural Sciences bred new varieties of super rice is one example Jijing -88. They have collected more than 10 countries from more than 150 parent resources from the initial identification, only the corresponding parents were screened for hybridization, after 10 years of effort before breeding them. Conventional breeding is to say,
the biggest advantages of conventional breeding without sophisticated equipment, whether it is the central unit of equipment, excellent condition, or relatively poor condition of the local agricultural research institutes, can use this method of breeding new varieties. Such as the current planted area in the country's five main corn Qianwan Mu varieties, both bred by the Central Agricultural University unit 108, also bred by Zheng Provincial Academy of 958, more regional agricultural bred by four single-1 No more.
conventional breeding techniques so the benefit of mankind, because it is not only deeply rooted in the soil of agricultural practices around the world, and it's halls of science in agriculture also has an unshakable position. Darwin's discussion of hybrid vigor, Mendel's laws of inheritance, and the modern form of the system and complete quantitative genetics, has repeatedly proved that conventional breeding is the most scientific, effective and safe breeding. Therefore, it is a
present, conventional breeding of new varieties bred problem is a longer period, usually 5-7 years, and more labor-intensive, requiring larger plots. However, the high survival rate of achieving the objectives, if we continue to be a year of uninterrupted crosses configuration, scientific analysis, observation and selection can make variety of constantly updated, new varieties gradually emerge. History of the development of modern agricultural production of new varieties can be said to continuously update and optimize history. The support of conventional breeding is continuous,bailey UGG boots, and only this can ensure breeding units can continue to provide for new varieties of local agricultural production. Therefore, conventional breeding should be to increase the continued support, which for a vast area, diverse climatic conditions where breeding units in China is very important. Note that in conventional breeding method of application of advanced biological technologies to speed up the breeding process and the full effect, must not, as some places, as a suppression of both a Young, a praise of a devaluation, trade-off, the real fell on the scientific development concept reality.
Second, the development of transgenic breeding should have a clear understanding of
agriculture is the largest bio-industries, and support the development of the industry is still the conventional breeding techniques. Currently, some departments of the error-oriented (that is, to exaggerate the effect of genetic breeding to the point of deification, tentatively called it situation, cold or even abandoned the conventional breeding, which is an abnormal trend, but also a dangerous sign.
Since the helical structure of DNA found in over half a century since, the worldwide commercialization of the gene has only two, one insect-resistant genes,Discount UGG boots, and second, herbicide-resistant genes are different from the so-called microbial genes, the former from Bacillus thuringiensis, which is derived from Streptomyces hygroscopicus. Academics on the safety of GM food concerns exist, precisely because of these different genes on the human body and the environment of the precise experiments yet to be confirmed, so all countries have strict laws to regulate genetically modified technology and product application. In addition, transgenic technology has also not fully mature, still stuck in the body, such as the Arabidopsis plants, it is difficult to form new varieties available to farmers. We believe that breeding new varieties of the main advantages and disadvantages should see it translated into effective productive capacity.
Third, the development of transgenic breeding Attention
transgenic breeding techniques for problems in the development of awareness and the existence of the errors made should be noted that the five aspects:
1, GM put a lot of investment in the national separation of independent intellectual property rights used in gene up, not all the genes with the people and turn, I really can not afford to be careful in the future or a place of their royalty intellectual property disputes, the litigation costs.
2, many of the biological food chain breeding non-transgenic technology, such as flowers, garden plants, industrial raw materials such as hemp, cotton fibers of biological and industrial starch plant.
3, in the use of food and other edible plant and animal species breeding research, try to pay attention as materials for biological gene homologous to avoid the chaotic species (such as what genes to human milk on the cow), deviation from the moral and other aspects of human life and health concerns that bio-security uncertainty.
4, do not over publicity touting no matter how good breeding is only one of many human beings. Transgenic breeding workers must endure loneliness, inhibition Fuzao the wind, to yourself, but not today submitted an practical application and industrialization often also different galaxy.
5, the most important national science and technology departments to pay attention to science, we should pay attention to guiding the breeding of conventional breeding and genetic engineering of equal treatment, support and jointly contribute to the development of modern agriculture.
