Problems solved by technology

Because the female flowers of this variety open first, the male flowers appear relatively late. In order to ensure the efficiency and purity of seed production, the existing technology: first, sow in stages, with a difference of 10 days between the two sowing dates, but the male flowers in the early stage still cannot meet the needs of seed production. At the same time, the difference in sowing date is relatively large, which increases the difficulty

Example Embodiment

[0039] Example 1 (hybrid seed production)

[0040] 1) Sowing: The male parent'Five-leaf fragrant loofah' will be planted in 50 holes on March 10, and the seedlings will be raised by electric heating lines; the female parent'Snake-shaped loofah' will be planted in 50 holes and seedlings will be raised on March 20 by electric heating lines; On March 30, when the seedlings grow to 2 leaves, spray gibberellin once on the male parent leaves, divided into 5 treatment concentrations, namely spray 0 (spray water as CK), 100, 200, 400 and 600ppm. The results showed that the 100ppm gibberellin treatment on the male parent had the best effect, which could promote early flowering of male flowers for 4 days and increase the number of male flowers.

[0041] 2) Planting: The male parent is planted in the greenhouse on April 7, and the female parent is planted in the greenhouse on April 17, and the parent parent ratio is planted in the seed production shed at a ratio of 1:20.

Example Embodiment

[0059] Example 2 (Conventional seed production)

[0060] Sowing: The first sowing date will be 50-hole seeding on March 10th, and the seedling will be grown by electric hotline; the second sowing date will be 50-hole seeding on March 15th, and the seedling will be raised by electric hotline; To 2 leaves, spray gibberellin once on the leaves, divided into 5 treatment concentrations, namely spray 0 (spray water for CK), 100, 200, 400 and 600ppm. The results showed that the 100ppm gibberellin treatment had the best effect, which could promote early flowering of male flowers for about 4 days and increase the number of male flowers.

[0061] 2) Planting: the first sowing date will be planted in the greenhouse on April 5th, the second sowing date will be planted in the greenhouse on April 10th, and the first and second sowing dates will be planted in the seed production shed at a ratio of 1:25.

[0062] 3) Pollen preservation: the day before 16:30-17:30, pluck the open male flower buds at...

Abstract

The invention discloses a method for improving seed production efficiency of a sponge gourd. The method comprises the steps of seeding the sponge gourd in two seeding dates in March, regarding the time when a female flower is opened above 15 nodes of the sponge gourd in the second seeding date as a pollination beginning period, picking off an opened male flower bud of a male parent at 16:30-17:30 of the day before pollination, keeping the male flower bud in a 4 DEG C refrigerator, selecting an unopened female flower bud from 14:30-17:30 of the pollination day, performing the pollination, shaking a seed gourd when a coat of the seed gourd becomes brown after 60 days from the pollination, and performing harvesting when a seed in the seed gourd rustles, wherein a difference between the first seeding date and the second seeding date is 5-10 days. The method adopts the advance pollination, and the female flower is unopened during the pollination, so that advance bagging is not required; complicated operation of bagging and bag removal for hybridization is saved; the hybridization manpower is greatly reduced; the hybridization efficiency is improved; a seed bud rate, the thousand kernel weight and a hybrid seed yield of the sponge gourd are increased.

Description

technical field [0001] The invention belongs to the field of vegetable breeding and relates to a method for improving seed production efficiency of loofah. Background technique [0002] 'Jiangshu 2' loofah is a high-quality early-maturing long rod-shaped hybrid variety bred by the Vegetable Research Institute of Jiangsu Academy of Agricultural Sciences. market potential. The female parent is the early-maturing long rod-shaped material 'Snake-shaped loofah', the first female flower node of this material is 6-7 nodes, and the female flower node rate is high; the male parent is the early-medium-maturing short rod-shaped material 'Wuyexiang' loofah, The first female flower node of this material is at 8-9 nodes, and the female flower node rate is relatively high; because the male parent material male flowers appear late, in order to ensure the hybridization efficiency and purity, the prior art: First, the male parent is generally sown 15 days earlier, but the male parent The ma...
