Abstract

The invention discloses a method for quickly identifying waterlogging resistance of eggplant. According to the seedling phenotypic changes, the eggplant is divided into a strong level, a medium level and a weak level in waterlogging resistance; according to two evaluation indexes of leaf color and shedding and the stalk morphology, the eggplant is quantified and classified and grade scoring criteria is set; according to the average score of each material to calculate the average membership function value, the comprehensive evaluation of waterlogging resistance is performed and an evaluation system is set up. The waterlogging resistance membership function value is used for comprehensively evaluating the waterlogging resistance of plants and the evaluation results are closer to reality. According to the method of the invention, the waterlogging resistance of eggplant can be simply, quickly and accurately obtained through the waterlogging form score average membership function values.

Description

technical field [0001] The invention relates to a method for identifying the waterlogging tolerance of eggplant, in particular to a method for quickly identifying the waterlogging tolerance of eggplant. Background technique [0002] Eggplant (Solanum melongena L.) is one of the top ten vegetable crops in the world and is cultivated in most regions of the world, especially in Asia, Europe, Africa, North America and other regions. China is the world's largest eggplant producer and the center of secondary origin of eggplant, and its cultivation area accounts for about 50% of the world's total. 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, rich in vitamins and minerals, especially vitamin E, P and iron. In addition, eggplant contains a variety of alkaloids with a wide range of medicinal value. [0003] The eggplant planted in the middle and lower reaches of t...
