Incompatibility and male sterility are two different mechanisms that can be used in plant breeding to prevent self-pollination and promote cross-pollination.
Incompatibility refers to the inability of a plant to produce viable offspring when self-pollinated or crossed with certain other plants. This can occur due to genetic factors that prevent successful fertilization or embryo development. For example, in some plant species, there are self-incompatibility genes that prevent pollen from the same plant from fertilizing the ovules. This promotes outcrossing and genetic diversity within the population.
On the other hand, male sterility refers to the inability of a plant to produce viable pollen. This can be induced through genetic manipulation or environmental factors. For example, cytoplasmic male sterility (CMS) is a common method used in plant breeding where the male reproductive organs are non-functional, resulting in plants that are unable to self-pollinate. This can be advantageous in hybrid seed production, as it allows for the production of hybrid seeds without the need for manual emasculation.
In summary, incompatibility prevents self-pollination and promotes outcrossing by preventing successful fertilization, while male sterility prevents self-pollination by rendering the plant unable to produce viable pollen. Both mechanisms are important tools in plant breeding for promoting genetic diversity and producing hybrid seeds.
