Embodiment 1

[0037] Embodiment 1, cotton hybrid seed production pollination tube and its application

[0038] 1. Making pollination tubes for cotton hybrid seed production

[0039] Cotton hybrid seed production pollination tube, comprising a hollow wax tube 1, one end of the wax tube 1 is open, the other end is closed with a soft material 2 matching the inner diameter of the wax tube 1, and the soft material 2 is located on the One end of wax tube 1 inside is stained with cotton male parent pollen 3. The inner diameter of the wax tube 1 is 5 mm; the length of the wax tube 1 is 2 cm. The soft material 2 is a sliver made of cotton twisted into strips. The diameter of the sliver is 4mm-5mm.

[0040] The wax tube 1 is manufactured as follows: paper is rolled into a tube with an inner diameter of 5 mm, immersed in melted paraffin, picked up and dried, and cut into a tube with a length of 2.0 cm.

[0041] The production method of the pollination tube for cotton hybrid seed production: take a...

Abstract

The invention discloses a cotton hybrid seed production method and a pollination tube. The cotton hybrid seed production method provided herein includes the steps of (1) collecting pollen from male parents; (2) producing the pollination tube, to be specific, making a small tube 5-5.5 mm in diameter by coiling paper, dipping the small tube in molten paraffin, taking out for airing, and cutting to obtain a wax tube 2-2.5 cm in length, wherein one end of the wax tube is opened, the other end of the wax tube is sealed with a soft material matching with the wax tube in inner diameter, the end of the soft material inside the wax tube is stained with the female parent pollen of step (1), and the pollination tube is produced; storing the produced pollination tube at 6-8 DEG C for backup; (3) sleeving with the pollination tube. The cotton hybrid seed production method provided herein is suitable for hybrid seed production for conventional parents and is also suitable for hybrid seed productionfor sterile lines; the cotton hybrid seed production method helps simplify seed production, greatly save cost and improve hybrid seed purity.

Description

technical field [0001] The invention relates to the field of agricultural technology, in particular to a cotton hybrid seed production method and a pollination tube. Background technique [0002] Heterosis is a ubiquitous phenomenon in the biological world. In the early 1920s and 1930s, crop heterosis had been widely used in production. The application of heterosis in cotton began in the 1980s. The use of cotton heterosis has greatly increased cotton production, improved quality, and enhanced cotton resistance. Therefore, cotton hybrids quickly occupied more than 80% of the cotton area in the entire Yangtze River Basin, and the cotton area in the Yellow River Basin and Xinjiang cotton area also developed rapidly. On a new level. However, in recent years, with the increase of labor costs in our country, the production cost of hybrids has increased year by year, making it difficult for many seed companies engaged in hybrid cotton seed production to continue, thus limiting t...
