Field identification method of disease resistance of sesame wilt

Abstract

The invention discloses a field identification method of disease resistance of sesame wilt, which includes main steps: step one, cultivation of a sesame wilt disease nursery; step two, fine land preparation and moderate sowing; step three, confirmation of planting density; step four, enhancement of field management of disease nursery; step five, disease investigation and grading; step six, evaluation of diseases resistance. Through cultivating the nature disease nurseries with different continuous cropping age limits, the field identification of the disease resistance of sesame wilt is carriedout, thus the major field identification efficiency of the disease resistance of sesame wilt is improved and the accuracy and repeatability of the disease resistance identification are improved; under the same cost and the nature disease nursery area, the method can evaluate once that the variety number of sesame is over 4-6 times of that in the prior art; the method can be applied to the diseaseresistance identification of the sesame variety while also applied to sesame wilt resisting breeding, thus the selective breeding, popularization and application of the disease-resistant variety areaccelerated to carry out.

Description

technical field [0001] The invention relates to the field of crop disease resistance identification, in particular to a method for field identification of sesame fusarium wilt disease resistance. Background technique [0002] Sesamum indicum L. is an annual herb belonging to the genus Sesamumgenus of the pedaliaceae family. It is one of the oldest high-quality oil crops in the world. It contains antioxidant substances such as sesamin, sesamol and vitamin E. And enjoy the reputation of "Queen of Oil". Sesame is one of the crops with the highest oil content in the world. The main components of its fatty acids are oleic acid (18:1) and linoleic acid (18:2), with a ratio of 1:1. [0003] As one of the four major sesame producing countries in the world, our country has carried out sesame genetics and breeding work earlier. Currently, there are hundreds of varieties bred, and the per unit yield and total yield are also among the best in the world. However, limited by the charact...

Problems solved by technology

However, limited by the characteristics of the species, the existing varieties still have problems such as poor disease resistance, low and unstable yield, and low degree of mechanization.
