Flower and lip hybrid F1 generation seedling propagation method

Abstract

The invention provides a flower and lip hybrid F1 generation seedling propagation method. The method includes that parent fish mature rate is up to higher than 75% by taking flower as a female parentand lip as a male parent and controlling parameter conditions during breeding, spawning induction and incubation, maturing time is orderly, brood amount is high, semen quality is high, parent fish egglaying time is uniform, and each of fertilization rate and incubation rate reaches higher than 90%. The method can be used for in-pond artificial seedling culture of hybrid F1 generation and is of important guiding significance in large-scale artificial breeding of F1 generation and comprehensive planting and breeding in a rice field.

Description

technical field [0001] The invention relates to the technical field of hybridization, in particular to a flower with lips Hybrid F1 generation seed propagation method. Background technique [0002] flower and lips Cyprinidae, Cyprinidae, Cyprinidae, belongs to. Distributed in major rivers, lakes, and reservoirs in my country, it is a small and medium-sized fish with high economic value. Its spawning period is from early April to early May, and it is a one-time spawning fish. Heavy eggs, high viscosity, pale white or light yellow eggs, fertilized eggs hatch at around 19-24°C for 26-29 hours. In recent years, artificially cultivated flowers and lips Oxygen consumption is high, stress is strong, and it is not easy to catch, which restricts its breeding area and promotion speed. [0003] Currently, in how to solve the flower and lips In terms of the shortcomings of high oxygen consumption and strong stress, no effective method has been found yet. Although h...

In recent years, artificially cultivated flowers and lips Oxygen consumption is high, stress is strong, and it is not easy to catch, which restricts its breeding area and promotion speed

[0003] Currently, in how to solve the flower and lips In terms of the shortcomings of high oxygen consumption and strong irritability, no effective method has been found

Although hybridization technology has a wide range of applications in cultivating fine varieties, it has very high requirements for the selection of hybrid female parents, parents, and hybridization process, otherwise it is difficult to obtain hybrids with better characteristics than their parents.
