Abstract

The invention discloses a method and a model for predicting the lodging resistance of soybeans. The method provided by the invention comprises the steps of (1) respectively measuring the numerical values of the following seven characters of the soybeans to be measured: stalk strength, plant height, stem diameter, branching number, root length, root weight and overground weight; (2) substituting the numerical values of the stalk strength, the plant height, the stem diameter, the branching number, the root length, the root weight and the overground weight into the lodging resistance model of the soybeans to calculate the lodging resistance: LR=174.162-6.618*BN-2.643*PH+15.165*RW+5.549*SD+0.108*SS+0.027*RL-0.483*SW, wherein if LR is more than or equal to 75, the soybeans to be measured are lodging-resistant soybeans or candidate lodging-resistant soybeans; if LR is less than 75, the soybeans to be measured are easy-lodging soybeans or candidate easy-lodging soybeans. The experiments prove that the method is convenient and fast, and is not influenced by environment.

Description

technical field

[0001] The invention relates to the field of biotechnology, in particular to a method for predicting soybean lodging resistance and a model thereof. Background technique

[0002] Soybean is an important crop, which plays an important role in the development of my country's national economy, the composition of world food crops and the production of international oil crops. It has become the main source of edible and forage vegetable protein and vegetable oil in all countries in the world. Plant lodging is a common and serious problem in soybean production, and has become one of the main limiting factors to achieve high, stable, and high-quality soybean yields. Lodging is a phenomenon in which plant stems change from a natural upright state to a permanent dislocation caused by external factors such as wind and rain. The middle and late stages of soybean growth coincide with the rainy season in summer. The surface is wet and the soil is loose, which is easy to c...
