Hybrid round eggplant seed production method

Abstract

The invention relates to a hybrid round eggplant seed production method and belongs to the technical field of vegetable seed breeding. The method comprises the steps of sowing, planting, pruning, pollinating and harvesting and is characterized in that: during the pruning, four-branch pruning is performed; door eggplants and opposite eggplants are removed; and pollination and fruits reservation are performed after buds of bucket-shaped eggplants are matured. The method has the advantages of simpleness, easy fruit setting, unified nodal region, nutrition insurance, uniform fruits, low seed production cost, high plant stress resistance, low fruit morbidity, many seeds in a single plant, high seed production yield and the like.

Description

technical field [0001] The invention belongs to the technical field of vegetable seed breeding, in particular to a hybrid purple eggplant seed production method. Background technique [0002] At present, eggplant (Solanum melongena L.2n=24), Solanaceae Solanum is a perennial small shrub-like herb. The growth cycle of purple eggplant is long, it usually takes about 200 days from sowing to seed harvesting, and 60-70 days from flowering to fruit ripening. Therefore, the traditional method of hybridization purple round eggplant seed production is double-dry pruning, pollinating and retaining fruit from the pair of eggplants at lower nodes, and after each plant has 3-4 fruits, remove the growing point for the whole plant. The advantage of this method is: early fruit setting, early maturity and early harvest. However, there are the following obvious disadvantages: 1. Because the fruit expands and consumes more nutrients, after the normal expansion of the low-node eggplant, the f...

AI Technical Summary

Problems solved by technology

However, there are the following obvious disadvantages: 1. Because the fruit expands and consumes more nutrients, after the normal expansion of the low-node eggplant, the four-door eggplant on the upper layer often cannot expand normally, usually with 2 large and 2 small fruit, or 2 large and 1 small

2. The incidence of fruit near the ground is high, such as cotton blight, brown spot disease, etc.

Especially during the fruit-filling period from July to August, the pathogenic bacteria can easily spread to the fruits on the ground along with agricultural operations and rainwater splashes, causing cotton blight, and then rot, seriously affecting the yield and quality of seeds, and even the seeds are poisonous.

3. Since the harvested fruits are distributed on the two branch nodes of eggplant and eggplant, the time span of pollination and harvesting is relatively long, and the labor cost increases

4. After removing the growth point, although the speed of fruit expansion is accelerated in the early stage, the fruit maturity period is advanced, but because the number of effective photosynthetic leaves of the whole plant is reduced, the plant often causes premature senescence and a decline in stress resistance
