Embodiment Construction
[0014] The present invention is mainly aimed at the flower selection and pollination link, and the detailed process of main hybrid seed production is as follows:
[0015] 1. Strict isolation: Although sweet peppers are often cross-pollinated crops, and the possibility of pollen spreading by wind is small, sweet pepper flowers are very attractive to insects, which can easily cause biological confusion and affect seed quality. Therefore, the isolation distance between sweet pepper farming fields and other sweet pepper varieties is required to be more than 500 meters.
[0016] 2. Sowing at the right time: The optimum temperature for the germination of sweet pepper pollen is 20-25°C, so seedlings of the right age should be cultivated by adjusting the sowing time and controlling the temperature. In order to make the parents reach the full flowering stage at the right time for hybridization, seedlings can be raised in cold beds. The early and mid-maturing varieties are sown in early...
