糯高粱籽粒淀粉含量及组分的配合力分析

用 1 8A等 4个糯高粱不育系与 3 5R等 5个糯高粱恢复系按Griffing方法Ⅱ组配成 2 0份组合 ,估算了糯高粱籽粒总淀粉含量、支链淀粉含量和直链淀粉含量的配合力。结果表明 ,同一亲本不同品质性状的配合力不同 ,同一品质性状不同亲本的配合力也不同。在酿酒品质性状的杂种优势利用上 ,选育优质酿酒高粱组合应选择总淀粉含量及支链淀粉含量一般配合力高的亲本

A Analysis of the Combining Ability of Starch Content in Glutinous Sorghum

The combining ability of total starch , amylase and amylopectin content in glutinous sorghum grain was reserched by means of incomplete dialled model with 4 sterile lines and 5 restoring lines. The result indicated that combining ability of different characters of the same parent or different parents of the same character was different. So the parents of glutinous sorghum with highGCA of total starch and amylopectin content must be selected in the utilization of quality character heterosis for making liquor.
