1. Limited genetic diversity: Self-incompatibility relies on genetic diversity within a plant population to ensure successful pollination. If the plant population lacks sufficient genetic diversity, self-incompatibility may not be effective in producing viable hybrid seeds.
2. Pollen contamination: Cross-pollination from nearby plants of the same species can lead to pollen contamination, resulting in self-pollination and reducing the effectiveness of self-incompatibility in hybrid seed production.
3. Environmental factors: Environmental conditions such as temperature, humidity, and wind can affect pollination and fertilization processes, potentially interfering with the success of self-incompatibility in producing hybrid seeds.
4. Inbreeding depression: In some cases, self-incompatibility can lead to inbreeding depression, which can result in reduced vigor and fertility in the resulting hybrid plants.
5. Labor-intensive process: Implementing self-incompatibility in hybrid seed production can be a labor-intensive process, requiring careful management of plant populations and pollination techniques to ensure successful hybrid seed production.

Factors Hampering Self-Incompatibility in Hybrid Seed Production:
- Breaking of Self-Incompatibility: Under certain conditions, such as extreme temperature, high humidity, or hormone treatments, self-incompatibility mechanisms can break down, allowing self-fertilization, which is undesirable in hybrid seed production.
- Cross-Pollination: Hybrid seeds require cross-pollination from different parents. Incompatibility systems can interfere with this process by preventing cross-pollination between incompatible partners.
- Multiple Incompatibility Systems: Some species have multiple incompatibility systems, making it difficult to select compatible genotypes for crossing.
- Environmental Influences: Environmental factors, such as temperature, humidity, and nutrient availability, can affect the expression of self-incompatibility, leading to inconsistent seed production.
- Limited Genetic Diversity: In some cases, limited genetic diversity within the breeding population may restrict the availability of compatible genotypes for hybrid seed production.
- Cost and Labor: Implementing self-incompatibility systems in hybrid seed production can be time-consuming and expensive, especially for species with complex genetic mechanisms.
