Embodiment 1
[0019] Example 1 Cultivation of flowering delayed loofah inbred line F224 and establishment of seed production method
[0020] Interspecific hybrid F1 plants were obtained by crossing the excellent ribbed loofah "Yagang loofah" as the female parent and the common loofah "Sanyezaoyoujia loofah" as the male parent. In Guangzhou, "Yagang Loofah" blooms from 16:00 to 18:00 in the afternoon, "Sanyezaoyoujia Loofah" blooms from 4:00 to 6:00 in the morning, and the F1 plants of the two hybrids bloom late at night from 22:00 to 23: 00 blossom.
[0021] BC1F1 seeds were obtained by backcrossing the interspecific F1 plants as the female parent and "Yagang Luffa" as the male parent. Plant about 100 BC1F1 plants, use "Yagang loofah" as the male parent, continue backcrossing, and mix BC2F1 seeds. Randomly select a batch of BC2F1 seeds for sowing, plant about 100 BC2F1 plants, continue to use "Yagang loofah" as the male parent for backcrossing, and mix BC3F1 seeds. Randomly select a bat...
Embodiment 2
[0027] Embodiment 2 Utilizes F224 to carry out small area seed production experiment
[0028] In the Baiyun Experimental Base of the Vegetable Research Institute of Guangdong Academy of Agricultural Sciences, the selected excellent inbred line F224 of loofah with ribs with delayed flowering time was used as the female parent, and the excellent inbred line of loofah with ribs was used as the male parent, and 20 plants were planted. There are 4 rows of female parent and 4 rows of male parent (row length 5 meters, row spacing 1 meter, plant spacing about 40cm). Seed production is carried out by artificial pollination, that is, during the flowering period, at 4:00-4:30 pm every day (at this time, the pollen is mature and will soon loosen, and the pollination effect is better). The plants are artificially pollinated, and after pollination, the flowers are listed. For the conventional seed production method, the worker must stop working when the female flower of the female parent...
Embodiment 3
[0029] Embodiment 3 utilizes F224 to carry out field seed production experiment
[0030]Guangdong Kenong Seed Industry Co., Ltd. uses F224 for field seed production in the loofah seed production base in Zhanjiang, Guangdong. The isolation of the seed production field is in good condition, and there is no loofah planting within 5 kilometers around. The base covers an area of 15 mu. The excellent inbred line F224 of ribbed loofah with delayed flowering time is used as the female parent, and the inbred line is used as the male parent. The male parent and the female parent are planted adjacent to each other. The planting volume is about 12 mu. The method of artificial detasseling is used for seed production, that is, during the flowering period, at 3:00-3:30 pm every day, workers are organized to remove the male flower buds of the female plant, and when the female flowers are open, artificial pollination combined with insect pollination completes the hybridization. After the...
