Embodiment 1
[0029] Pepper variety: Yanjiao No. 1
[0030] A method for improving efficiency and yield of capsicum hybrid seed production, comprising the following steps:
[0031] (1) Adjust the sowing date: Seeds were produced in early spring facilities in Yancheng, Jiangsu Province, and sowed on December 20. The male parent was sown 7 days earlier than the female parent, and the electric heating wire warmed the bed to raise the seedlings;
[0032] (2) Reasonable dense planting: On March 15th of the second year, the facilities were planted in the greenhouse, the planting ratio of the father and mother was 1:4, and the nylon mesh was covered with two arches in the facility greenhouse, and the parents were planted on the nylon mesh respectively. In the gauze, the gauze is sealed around the gauze to isolate foreign pollen, and the seeds are isolated and multiplied. The purity of the parent parent is measured to reach 99.9%. The cultivation density of the male and female parents is determined...
Embodiment 2
[0041] Pepper variety: Yanjiao No. 2
[0042] A method for improving efficiency and yield of capsicum hybrid seed production, comprising the following steps:
[0043] (1) Adjust the sowing date: Seeds were produced in early spring facilities in Yancheng, Jiangsu Province, and sowed on December 20. The male parent was sown 10 days earlier than the female parent, and the electric heating wire warmed the bed to raise the seedlings;
[0044] (2) Reasonable dense planting: On March 10th of the second year, the facilities were planted in the greenhouse, and the planting ratio of the father and mother was 1:4. Two arches were used to cover the nylon mesh in the facility greenhouse, and the parents were planted on the nylon mesh respectively. In the gauze, the gauze is sealed around the gauze to isolate foreign pollen, and the seeds are isolated and multiplied. The purity of the parent parent is measured to reach 99.9%.
