小豆种质资源子粒淀粉和支链淀粉含量分析

对小豆主产区的325份种质资源的子粒总淀粉和支链淀粉相对含量进行了鉴定评价.结果表明:小豆子粒中总淀粉含量为44.79%～67.44%,平均为57.06%;支链淀粉相对含量为62.61%～98.94%,平均为82.24%;品种间差异均达极显著.筛选出总淀粉高于62.64%和支链淀粉相对含量高于93.57%的种质资源各16份、直链淀粉相对含量高于29.14%的种质资源13份.

Analysis of Whole Seed Starch and Amylopectin Contents in Adzuki Bean Germplasm Resources

Seed whole starch contents and amylopectin contents of 325 adzuki bean germplasm resources from major production areas in china were appraised. The results indicated that seed whole starch contents of adzuki bean were 44.79 % - 67.44 %, with the mean of 57.06 % ; amylopectin relative contents were 62.61% 98.94 %, with the mean of 82.24 % ; the differences among varieties were extremely remarkable. We obtained 16, 16 andl3 germplasm resources whose whole starch contents exceeded 62.64%, amylopectin relative con- tents exceeded 93.57 % and amylose contents exceeded 29.14 %, respectively.
