Studies on Buckwheat the Quality Kernel Properties of Autotetraploid

The method of buckwheat cultivation, the availability of soil nutrient, temperature, humidity and other ecological condi-tions certainly affect buckwheat qualities. The difference in the yield could be the important comparision of diploid and tetraploid buckwheat. Details are not yet known, if there are important differences of the quality and utilization value between diploid and its autotetraploid, as well diploid tatary varieties? The physical and chemical properties of buckwheat kernels and flours were analysed. The common autotetraploid variety Yuqiao I has much greater kernel than its diploid Mudanqiao and tatary variety Yuqiao 6-21, but the centigrade variance (CV%) in a kernel weight of teteraploid also greater. The different fractions of flour in different ways to milling may have different chemical compositions and also different value of nutrition and utilization. There are no obvious differences in protein, amino acids, ash, minerals and crude fibre content between common diploid and its autotetraploid as well tatary cultivations. Buckwheat flour has a relativily higher content of ash, fibre, amino acids and minerals than wheat flour. The genetinization temperature and resistance of buckwheat flour are higher than that of wheat flour Meneba
