Genetic Transformation,Kelly & Miklas). In the past, plant geneticists tried to make use of radiation- or chemically-induced mutations, but the respective low frequencies and occurrence of many recessive and loss-of-function mutations failed to convince breeders of the value of these techniques. In addition, in the era of商品 发表于 2025-3-23 13:51:51
Integrated Genetic Improvement,, characterization, and screening methods, including identification of useful genes and different types of markers for their direct and indirect selection. Alternative recombination and selection methods have also been developed. On the other hand, there has been a growing concern for conservation a刻苦读书 发表于 2025-3-23 19:43:09

The selectable trait must be under simpler genetic control than the trait of interest and methodologies must be available that would favor its selection. For manySynapse 发表于 2025-3-24 20:07:42
