1) Some people look at the large ears of wheat varieties (mainly in Henan Province).
2) Some people look at the number of ears per mu of wheat varieties (mainly in Hebei Province and Shandong Province).

3) Some people look at the disease resistance of wheat varieties (all wheat regions should be noted).
4) Some people look at the "large grains" of wheat varieties (all wheat areas should be noted, because large grains = developed root system).
5) Some people look at the drought resistance of wheat varieties, the higher the 1000-grain weight = the stronger the drought resistance.
6) Some people look at the lodging resistance of wheat varieties - this is divided into several "schools": some like dwarf stalks, some like medium straws, some like hard stalks, some like straw elasticity, it can be said that [the public says that the public is reasonable, and the mother says that the mother is reasonable], but the real science is the "trinity": the root system is developed (the grain is large, the approved 1000-grain weight is high) + the stem toughness is good (the straw is not hard or soft) + resistance to rhizome rot (resistance to "withered white ears"), all three are indispensable. It is very naïve to think that "dwarf stalks resist falling" and "kindergarten-level cognition".

7) Some people look at the ability of wheat varieties to resist dry and hot winds.
8) Some people look at the ripening period - some like early ripening, some like late ripening, in fact, medium maturity (and most local varieties are basically the same maturity period is the best), early ripening yield is low, late ripening is easy to reduce yield (prone to dry hot wind and hail).
The above can be described as "turnip greens, each has his own love", some are #agricultural real technology#, and some are "pseudoscience", only by thinking more and comparing more, will you not be deceived. Because, really good varieties are always scarce.
In addition to the above aspects, many people ignore an important indicator: bulk density.
The higher the bulk density of wheat (at least 820 g/l on average), the greater the overall advantage. You know why?
Because, the higher the bulk density = the better the grain filling = the root system is developed (deep into the soil to absorb the accumulated nutrients for decades, which can save fertilizer and water and high yield) = less fertilizer, higher yield = 200 catties of yield per year compared with the neighbors, and it is also conducive to the "less fertilizer, higher yield" of the next corn (and Lai's wheat varieties will lead to the "green wilt" and "yellow wilt" of the next corn and reduce the yield).
Wheat varieties with poor grain filling must not have high bulk density, and low bulk density = poor resistance to yield reduction (easy to reduce yield).
What are the current wheat varieties with high bulk density?
1) "Baoyan 12" cultivated by the regular Academy of Agricultural Sciences, the approved bulk density and bulk density are 829 g/L - the approved disease resistance identification "with 3 resistances", and the approved "yield per mu" is 726 kg to 801 kg.
2) "Shimai 32" bred by the Formal Academy of Agricultural Sciences, the grain bulk density for two years was 819 g/L and 823 g/L respectively - very stable between years, with an average of more than 820 g/L, the approved disease resistance identification "double rust resistance", and the approved "yield per mu" was 709 kg.
3) "Round Selection 122", the approved bulk density is 827 g/L - the approved disease resistance identification "double rust resistance", and the approved "yield per mu" is more than 700 kg.
4) "Zhongjie No. 3" - two years of quality inspection results: bulk weight 797 g/L, 840 g/L - the gap between the years is large, and the disease resistance is not as good as the previous three varieties (the disease resistance identification of the variety is "4 medium susceptibility, one high susceptibility", although it is stronger than the "three high susceptibility" or "four high susceptibility diseases" of other varieties, but there is no "resistance" appeared), so the "yield per mu" is 669 kg.
After you learn how to compare these 4 wheat varieties, you can compare them to any other wheat variety. #小麦真科技#
