Simple isolation method for Solanum melongena flowering stage pollination

Abstract

The invention discloses a simple isolation method for eggplant flowering stage pollination, which belongs to the technical field of plant hybridization. The method of the present invention comprises the following steps: (1) selecting a cotton thread with a diameter of 0.7-1.0mm and a length of 8-10cm, and beating the cotton thread into a live button that can be pulled back and forth; (3) collect the male parent's anthers, and dry them for later use; (4) take off the cotton thread loops, pollinate, and tie the cotton thread loops on the top of the female parent's flower buds again. The invention makes the eggplant hybridized flowers have better ventilation and light transmission, avoids the phenomenon of fruit drop and rotten fruit, and greatly improves the fruit setting rate of the hybridized flowers. At the same time, the cotton thread is easy to operate and the cost is low, which can effectively improve the time of the producer and improve the economic benefits.

Description

technical field [0001] The invention relates to a simple isolation method for eggplant flowering stage pollination, in particular to a method for field eggplant hybrid seed production, and belongs to the technical field of plant hybridization. Background technique [0002] Eggplant (Solanum melongena L.) is widely cultivated in most parts of the world, and the Food and Agriculture Organization of the United Nations lists eggplant as the fourth largest vegetable crop. China is the largest eggplant producer in the world, and it is also the secondary origin center of eggplant, and its cultivation area accounts for about 50% of the world. In 2013, the planting area of ​​eggplant in my country was 801,000 hectares, and the total output reached 28.4558 million tons. Eggplant has high nutritional value and also contains a variety of alkaloids, which have medicinal value. Eggplant is currently the third largest crop in the Solanaceae crops after potatoes and tomatoes. It is a popu...

Problems solved by technology

But there are serious drawbacks in this method: 1. The effect of binding the flower buds cannot be achieved by tightening the cotton thread at all. With the blooming of the flower buds, the tightened cotton thread will be quickly opened. At this time, the effect of the cotton thread will disappear completely, and the flowers are easy to bind. Contaminated by other pollen

2. The method of tightening the cotton thread used in this article has extremely high requirements on the cotton thread. The surface of the cotton thread must have a lot of fluff to make the two cotton threads entangle with each other. After all, the cotton thread is not an iron wire, so it is very difficult to tighten it.

3. It takes more time to complete the work of thread twisting, which is a time-consuming and laborious work for breeders and farmers
