Embodiment 1

[0016] The selected demonstration field is located in the seed production base of China Tobacco Seed Co., Ltd. in Yuxi, Xishuangbanna, Yunnan. Tobacco seedlings are raised by floating seedlings, which are then transplanted to the field after they grow into seedlings. Field planting density: row spacing 1.2m, plant spacing 0.5m.

[0017] Field implementation of 25 mu of land was carried out in the seed production base. Among them, 5 mu was used as the male parent of MS Yunyan 87, and the remaining 20 mu was used for planting the female parent of MS Yunyan 87. The anthers of the male parent of MS Yunyan 87 were collected in the field, dried to loosen the powder, sieved with a 50-mesh sieve, collected and sealed at 4°C for future use. Mix the starch and the pure pollen of the male parent of MS Yunyan 87 uniformly at a volume ratio of 1:2 to prepare the required solid medium pollen.

Embodiment 2

[0019] Field implementation of 25 mu of land was carried out in the seed production base. Among them, 5 acres are used as the male parent of MSK 326, and the remaining 20 acres are used to plant the female parent of MSK 326. The anthers of the male parent of MSK 326 were collected in the field, dried to loosen the pollen, and the pollen was screened out with a 50-mesh sieve, and the pollen was collected and sealed and stored at 4°C for later use. Mix the starch and the pure pollen of the male parent of MSK 326 uniformly at a volume ratio of 1:2 to prepare the required solid medium pollen.

Embodiment 3

[0021] Field implementation of 25 mu of land was carried out in the seed production base. Among them, 5 mu is used as the male parent of MS Yunyan 85, and the remaining 20 mu is used for planting the female parent of MS Yunyan 85. The anthers of the male parent of MS Yunyan 87 were collected in the field, dried to loosen the powder, sieved with a 50-mesh sieve, collected and sealed at 4°C for future use. Mix the starch and the pure pollen of the male parent of MS Yunyan 85 uniformly at a volume ratio of 1:2 to prepare the required solid medium pollen.

Abstract

The present invention discloses a solid media pollen, a preparation method and the application thereof. Tobacco pollen parent anther is collected and aired to loose pollen; the pollen is sieved by a 50-mesh sieve; starch or flour is mixed with the collected pure tobacco pollen evenly according to the volume ratio of 1:2-4; and the required solid media pollen is obtained. The solid media pollen is dipped by a cotton swab or a brush pen and is smeared on a female parent tobacco flower stigma for artificial pollination. The use of the solid media pollen improves the effective utilization rate of the tobacco pollen, reduces the usage amount of the pure pollen, saves the manpower and material resources used for collecting the pollen and reduces the planting area of tobacco pollen parent and the hybrid seed production cost. The popularization and the application of the technology have good economic benefit and social benefit.

Description

technical field [0001] The invention belongs to the technical field of artificial pollination, and relates to artificial assisted pollination for tobacco hybrid seed production, in particular to solid medium pollen. At the same time, the invention also relates to the preparation method and application of the solid medium pollen. Background technique [0002] Tobacco (Nicotiana tabacum L.) is an important economic crop and an important source of fiscal revenue in our country. With the development of tobacco agriculture in the world, the popularization and application of tobacco male sterile lines has gradually become one of the main development directions of tobacco leaf production in my country. At present, the technology and production mode of tobacco male sterile lines have been widely promoted and applied in tobacco agricultural production. The planting area of ​​tobacco male sterile lines is expanding year by year, and the amount of seeds used is also increasing year by...
