In a plant breeding program, the breeders noticed that some plants had a much higher resistance to a certain disease compared to others. After investigation, they found that it was related to a small change in the DNA sequence. This small change is _. A. A genetic variation B. A genomic...

According to the passage, what is the purpose of plant breeding?A. To beautify the environment.B. To change the genes of plants.C. To produce preferable plant varieties.D. To assess the value of the practice. Why could plant breeding ensure food security?A. Because higher production is gua...
Traditional plant breeding(培育) involves crossing varieties of the same species in ways they could cross naturally. For example, disease-resistant varieties of wheat have been crossed with high-yield wheat to combine these properties. This type of natural gene exchange is safe and fairly predictable...
plant breedingselectionThe goal of this project is to establish the BLUP breeding value prediction (best linear unbiased prediction) under the conditions of plant breeding. The BLUP breeding value prediction is so far only used in animal breeding. On a long-term basis the number of test crosses...
育种值 breeding value 基因加性效应 additive effect of genes 所携基因的平均效应之和。 注:其数值是个体与一些从群体随机抽取的个体交配时获得,其子代平均值距其群体平均值的平均离差的两倍。 林木选择育种 selective breeding of forest tree, forest tree selection breeding ...
Primary goals of plant breeding with agricultural crops have aim to improve yields, nutritional qualities, and other traits of profitable value. Globally, the plant breeding model has been very much successful, with the development of hybrid maize (Zea mays), the introduction of wheat (Triticum ...
Prediction of Genetic Values of Quantitative Traits in Plant Breeding Using Pedigree and Molecular Markers The availability of dense molecular markers has made possible the use of genomic selection (GS) for plant breeding. However, the evaluation of models for G... J Crossa,Campos, G. d. l....
Intellectual property protection, globalization, and pressure on public budgets in many industrialized countries have shifted the balance of plant breeding activity from the public to the private sector. Several economic factors influence the relative shares of public versus private sector plant breeding ac...
