小麦品种出粉率与其品质性状关系的研究

对近２０年来黄淮冬麦育成推广的５３个小麦品种的测定结果表明，参试品种容重平均值７７６．１ｋｇ／ｈ，硬度平均值４７％，出粉率平均值６０．３％。多数品种测定值 于国外对照品种，但亘个别品种优于最好的对照品种，如Ｎ８２－１０，小偃６号，Ｄ１０－２和冀８４－５１０３等；出粉率和容重有极显著正相关性、出粉率为ＨＭＷ－谷蛋白亚基组成的回归方程显著，利用该方程预测出粉率效果良好。

STUDY ON RELATIONSHIP BETWEEN FLOUR YIELD AND OTHER QUALITYCHARACTERISTICS OF WHEAT VARIETY

The 53 main wheat varieties cultivated in Hang-huai winter wheat area,bred in near 20 years,have been analysed.The results indicated that the average of test weight is 76. 1kg/hl.,hardness is 47%,and flour yield is 60. 3%.The test values of the most varieties are lower than that of foreign check varieties,but a few varieties are better than the check varieties. Such as D10-2, Xiaoyan No. 6,N82(2)-10,Ji 84-5103;The flour yield has a significant positive correlativity with the test weight. Moreover,it is intimatly correla-tive with high molecular weight glutenin subunit composition in their regression equa-tion. So that effect of flour yield forecasted with the equation is reliable. This research has an extremely important significance in both theory and economy on such aspects asthe wheat quality breeding and the development of milling industry.
