Почему мужская стерильность оказывается полезной при селекции некоторых культур

Answer 1

Мужская стерильность оказывается полезной при селекции некоторых культур,так как в результате получаем исходное сортовое с надлежащими физиологическими свойствами интенсивности развития,ЗАКОНОМЕРНОСТЬ НАСЛЕДОВАНИЯ сохраняется,мутагенез здесь отсутствует при внедрении другого вида,получении чистой линии данного вида сорта.

Answer 2

The Benefits of Male Sterility in Selecting Certain Cultures

Male sterility can be advantageous in the selection of certain cultures for several reasons. Here are some potential benefits:

1. Preventing Unwanted Cross-Pollination: Male sterility can be used as a tool to prevent unwanted cross-pollination between different varieties or species of plants. By eliminating the ability of male plants to produce viable pollen, breeders can ensure that only desired pollen from specific plants is used for pollination.

2. Facilitating Hybridization: Male sterility can facilitate the process of hybridization in plant breeding. By using male-sterile plants as one parent and a fertile plant as the other parent, breeders can easily produce hybrid offspring without the need for manual emasculation (removal of male reproductive organs).

3. Simplifying Seed Production: Male sterility can simplify the production of hybrid seeds. In hybrid seed production, it is desirable to prevent self-pollination and maintain the purity of the hybrid. Male-sterile plants can be used as the female parent, ensuring that only pollen from the desired male parent is used for pollination. This simplifies the process and reduces the risk of unwanted self-pollination.

4. Enhancing Crop Yield and Quality: Male sterility can be used to enhance crop yield and quality. By eliminating the energy expenditure on male reproductive organs, male-sterile plants can redirect their resources towards vegetative growth and the production of larger and more nutritious fruits or grains. This can result in increased crop yield and improved quality.

5. Controlling Invasive Species: Male sterility can also be used as a means of controlling invasive plant species. By introducing male-sterile varieties of invasive plants into an ecosystem, breeders can prevent these plants from producing viable pollen and spreading further. This can help to reduce the negative impacts of invasive species on native ecosystems.

It is important to note that the benefits of male sterility in plant breeding depend on the specific goals and requirements of the breeding program. Different breeding strategies may be employed based on the desired outcomes and the characteristics of the target crop or species.

Overall, male sterility can be a valuable tool in the selection of certain cultures, allowing breeders to control pollination, facilitate hybridization, simplify seed production, enhance crop yield and quality, and control invasive species.
