Embodiment 1
[0031] Embodiment 1 A kind of seed production method of flue-cured tobacco male sterile line
[0032] 1. Sowing
[0033] 1-1 Determination of the planting quantity and ratio of male and female parents
[0034] Calculate the planting area of the female parent according to the planned multiplication amount at 100 kg / ha, and calculate the area of the male parent at a ratio of 1:4 for the parent parent. The parent plants were planted in different fields or the same field was divided into two parts according to the area ratio of 1:4, and the planting areas of the parents were marked with conspicuous signs in the field to facilitate the operation and management of seed production.
[0035] 1-2 Determination of parental sowing time
[0036] According to the characteristics of the parents of the breeding varieties, the time from sowing to the initial flowering period of the parents is estimated this year from sowing to the initial flowering period. The female parent's initial f...
experiment example 1
[0059] The harvested fruits of the tobacco plants described in Example 1 and Comparative Example 1 are placed in a dry and ventilated air-drying building in time, and are dried in the sun after a certain period of post-ripening with a clean color strip cloth or plastic mulch. Threshing, after multiple screenings, after winnowing, sterilize with 2% copper sulfate solution for 15 minutes, then wash with clean water, then pad it with cotton cloth and re-dry it, then winnow, then bag and hang the label, measure the yield .
[0060] For the basic comparison of the flowering and pollination period, seed production yield, and pollination efficacy of Example 1 and Comparative Example 1, see Tables 1-2 for specific comparison results.
[0061] The flowering and pollination period of the female parent described in Table 1 embodiment 1 and comparative example 1
[0062]
[0063] Table 1 shows the early flowering stage, the end stage of flowering and the pollinable flowering stage of ...
