Identification method of photoperiod sensibility quantization of wheat

Abstract

The invention discloses an identification method of photoperiod sensibility quantization of wheat. Mainly aiming at Huanghuai winter wheat areas, the identification method of the photoperiod sensibility quantization of the wheat includes: planting a wheat material to be identified and a comparison material in different periods, wherein the planting periods include an early planting period and a late planting period at an interval of 40 days, and the last planting period ends before the end of November; performing regular farming management to avoid soil drought and fertilizer deficiency; accurately recording heading periods of every material in the early and the late planting periods; calculating difference between the heading periods of every material in the early and the late planting periods, and normally the difference is 1-20 days. The larger the difference between the heading periods is, the stronger the photoperiod sensibility of the material is, the smaller the difference between the heading periods is, the weaker the photoperiod sensibility of the material is, and thus the photoperiod sensibility of the wheat can be quantitatively evaluated. In addition, aiming at the photoperiod sensibility, phenotypic functional identification is performed directly, the photoperiod sensibility can be quantitatively identified, and the identification method is simple, convenient, fast and efficient in technology.

Description

technical field [0001] The invention belongs to the technical field of grain and crop research, and in particular relates to an identification method for quantifying the photoperiod sensitivity of wheat (mainly for the Huanghuai winter wheat region). Background technique [0002] Vernalization characteristics and photoperiod sensitivity determine the developmental process of wheat, are important physiological characteristics that affect wheat adaptability, and are also key research contents to break through the bottleneck of wheat yield through developmental regulation at present and in the future. Photoperiod sensitivity is a complex physiological trait of wheat varieties, which is controlled by multiple genes and is a controlling factor for wheat growth and development. The role of photoperiod sensitivity is not only to accelerate the development of long sunshine, but also to make a certain sunshine length node correspond to the specific developmental period of the plant, ...
