Embodiment

[0028] This experiment was carried out at the Xinjiang wheat breeder Zepu base in 2017; the test materials were 20 wheat varieties with different shade tolerance screened according to the previous yield results (see Table 1); the light treatment was set as the control of low light and natural light Two treatments; 3 repetitions are set up in the experiment, each repetitive sowing area is 1m 2 The test material was sown on October 15, 2016, and the shading net was constructed when the winter wheat was in the jointing stage on April 15, 2017, and the shading rate was 70%. The test material was subjected to low light stress, and the plant grew to bloom Begin to measure the relevant traits during the period; the cultivated aquatic products and management measures for each treatment during the test period are consistent.

Abstract

The invention discloses a wheat shade tolerance comprehensive identification model, a method and an application, relating to the agricultural planting field. The identification model is: D=- 1.049+0.357Tr+0.485MSW+0.756PL+0.179SLA+0.206WDW; Tr is the transpiration rate of wheat leaves, unit mmol-m-2-s-1; MSW is the kernel weight of main spike of wheat, unit g; PL is ear length of wheat, unit cm; SLA is specific leaf area of wheat in cm2 / g; WDW is wheat ear dry weight, unit g; the greater the value of D, the stronger the shade tolerance of the wheat. The identification model of the invention can be used for evaluating the shade tolerance of winter wheat, can measure the above five indexes of other winter wheat varieties under the same conditions, can obtain the shade tolerance coefficient thereof, and can obtain the comprehensive evaluation value D of the shade tolerance by using the model, and can scientifically and effectively predict the shade tolerance of different winter wheat varieties.

Description

Technical field [0001] The present invention relates to the field of agricultural planting technology, in particular to a comprehensive identification model, method and application of wheat shade tolerance. Background technique [0002] The identification indicators of plant shade tolerance are closely related to the genetic factors of plants and the external environment, and as many indicators as possible are used for comprehensive evaluation. The relative value of the index can more accurately reflect the shade tolerance ability of the plant than the absolute value. For the evaluation of soybean shade tolerance, there have been related studies. Chen Huaizhu and others have selected biological yields at the pod stage, plant height at harvest stage, minimum pod height, number of pods per plant, which are highly affected by shade, closely related to shade, and easy to operate. The number of seeds per plant, the weight per plant and the weight of 100 seeds are used as index traits...
