Embodiment 1

[0032] 1) sowing: on August 10, 50 holes were used to sow seedlings;

[0033] 2) Removal of miscellaneous and inferior plants: Before and after the planting of the seed plants and during the bolting and flowering period, a strict selection of the seed plants should be carried out once to eliminate the miscellaneous plants and diseased and inferior plants that do not conform to the characteristics of the strains.

[0034] 3) Colonization: On September 20, when the seedlings grow to 6-7 leaves, they can be planted. The row spacing between plants is 38cm×48cm.

[0035] 4) For the female parent '410', the method of cutting bulbs was adopted. For the female parent, the leaf bulbs were marked with a "cross" (CK), 1 / 3 leaf bulbs were cut off, 1 / 2 leaf bulbs were cut off, 2 / 3 leaf bulbs were cut off, and The method of cutting off the whole leaf ball was used for cutting the bulb; the results showed that: compared with the control, different cutting methods promoted the female parent t...

Embodiment 2

[0045] test group:

[0046](1) On August 10th of the first year, the female parent and male parent of 'Tanchun' were sown and raised, and the female parent '410' and male parent were bred in the middle and late September when the seedlings grew to 6-7 leaves. '423' was planted in the seed production shed at a ratio of 2:1, with a row spacing of 38cm×48cm and normal management;

[0047] (2) In the first ten days of February of the second year, about 2 / 3 of the leaf balls of the female parent '410' were cut off, subject to keeping the main bud at the base;

[0048] (3) At the end of February of the second year, cut a cross on the leaf ball of the male parent '423' with a knife, as long as the main bud at the base is not scratched;

[0049] (4) In the first and middle days of March of the second year, when the leaves are peeled off and the flower buds are seen, spray 350ppm gibberellin to the female parent '410', spray once every three days, and spray twice in a row;

Abstract

The invention discloses a method for improving the seed production and quality of the head cabbage hybrid 'Tanchun'. Sow the female parent '410' and the male parent '423' of 'Tanchun' in the first and middle August of the first year, and plant them when the seedlings grow to 6-7 leaves; Cut balling treatment, the male parent '423' was balled in late February of the following year; in the first and middle March of the following year, when the leaves were peeled and the flower buds were seen, the female parent '410' was sprayed with gibberellin; When the main shoots of the female parent '410' just exposed the leaves, half of the main shoots were knocked off; a week later, the tops of the primary branches were wiped off; when the seed pods turned yellow and the seeds turned brown, the parent The upper seeds are harvested separately, dried and threshed in time. Through the above-mentioned means, not only the flowering period of the parents can be met, but also the method is simple and easy, and the yield and quality of the cabbage seed production can be effectively improved.

Description

technical field [0001] The invention belongs to the field of vegetable cultivation, and relates to a method for improving the seed production and quality of the head cabbage hybrid 'Tanchun'. Background technique [0002] 'Tanchun' is an early-maturing, bolting-resistant, beef heart cabbage F bred by the Vegetable Research Institute of Jiangsu Academy of Agricultural Sciences. 1 In modern times, this variety performed well in Jiangsu, Zhejiang, Shanghai, Yunnan, Guizhou, Sichuan and other places. It is deeply loved by growers and has great market potential. The female parent is the self-incompatibility line '410', the leaf ball of this material is bovine heart-shaped, the leaf ball is full, and the first flowering period is in the middle and late April of the normal year; the male parent is the self-incompatibility line' 423', the material is bovine heart-shaped, and enters the initial flowering period in early April in a normal year. The difference between the flowering p...
