Green-sepal low temperature resistant eggplant breeding method

Abstract

The invention relates to a green-sepal low temperature resistant eggplant breeding method, and belongs to the technical field of breeding in the agricultural production. A stable line CL-1-21-2-3-10 obtained through hybridization of an excellent line 98-148-2-3-1-81 and an introduced Holland variety Lucia and multi-generation self-crossing and an excellent line B-3-8-3-21-2-2 obtained through multi-generation separation, purification and breeding of an introduced Holland variety Brigitte are crossbred as a female parent and a male parent respectively to obtain 08-5 named Langqi. The obtained Langqi has the characteristics of green sepal, low temperature resistance, long rod-shaped fruits and the like.

Description

Technical field: [0001] The invention relates to a breeding method of eggplant varieties, in particular to a breeding method of hybrid green sepals and low temperature resistant eggplant, which belongs to the technical category of breeding in agricultural production. Background technique: [0002] Due to its special growth characteristics, fruit characteristics and domestic cultivation environment, the eggplant varieties currently in production have restricted the production and promotion of eggplant. The main restrictive factors are: 1. The fruit is not resistant to low temperature. The varieties currently produced and used show fruit set at low temperature 2. The fruit is not resistant to storage, and it is generally recognized in production and the market that foreign varieties have good commerciality, roundness, good hardness, and good durability. Transportation, good luster, while domestic varieties are not resistant to transportation and are perishable; the general sto...

Problems solved by technology

[0002] Due to its special growth characteristics, fruit characteristics and domestic cultivation environment, the eggplant varieties currently in production have restricted the production and promotion of eggplant. The main restrictive factors are: 1. The fruit is not resistant to low temperature. The varieties currently produced and used show fruit set at low temperature 2. The fruit is not resistant to storage, and it is generally recognized in production and the market that foreign varieties have good commerciality, roundness, good hardness, and good durability. Transportation, good luster, while domestic varieties are not resistant to transportation and are perishable; the general storage period is about 3-4 days; 3. The disease resistance of the variety is not strong, and the currently cultivated varieties are resistant to bacterial wilt and Verticillium wilt Weak; 4. The cultivation environment and cultivation technology requirements are high. Eggplant cultivation needs to be cultivated on a stand under protected land conditions. The cultivation technology and soil requirements are strict, otherwise the yield and quality will decline

Due to the above reasons, although eggplant has been planted in China for many years, and the product price is relatively high, the growth of the cultivated area is slow, and the variety and cultivation technology are the main factors to promote this eggplant
