Jimai 44 yield

Top of the form

Jimai 44 is a variety selected after crossing between Jinan 17 and line 954072. At present, it is a wheat variety with relatively high yield, so what is the yield of Jimai 44?

I. yield of Jimai 44

In the regional trial of high fertilizer group of wheat varieties in Shandong Province from 2015 to 2017, Jimai 44 had an average yield of 603.7 kg per mu in two years, 2.3% higher than that of Jimai 22, an average yield of 540.0 kg per mu and 1.2% higher than that of Jimai 22, a control variety.

II. Characteristics of Jimai 44

Winter, semi-creeping seedlings, semi-compact plant type, light green leaves, flag leaves, good lodging resistance and good ripening phase. The average results of the two-year regional test were as follows: the growth period was 233days, which was 2 days earlier than that of Jimai 22; the plant height was 80.1cm, the tiller per mu was 1.02 million, the effective panicle per mu was 438000, the panicle rate was 44.3%; the panicle was rectangular, the number of grains per spike was 35.9g, the 1000-grain weight was 43.4g, the bulk weight was 788.9 g / L; long awn, white shell, white grain, hard grain. In 2017, the inoculation results of the Institute of Plant Protection, Chinese Academy of Agricultural Sciences showed that they were moderately resistant to stripe rust, moderately susceptible to powdery mildew, highly susceptible to leaf rust, scab and sheath blight. The overwintering cold resistance is better. The 2016 and 2017 regional test unified sampling was tested by the Grain quality Supervision, Inspection and testing Center of the Ministry of Agriculture (Taian). The average results are as follows: grain protein content 15.4%, wet gluten 35.1%, sedimentation value 51.5ml, water absorption 63.8ml/100g, stable time 25.4min, flour whiteness 77.1, is a strong gluten variety.

The yield of Jimai 44 is relatively high, and the benefit of planting is also relatively good. When planting, we need to pay attention to the control of leaf rust, scab and sheath blight.
