小麦推广品种与糯性系杂交后代糯小麦材料选择的研究

Study on the Selection of Waxy Wheat from Early Generations of Crosses between Released Varieties and Waxy Lines in Wheat

选用生产上推广的皖麦18号、扬麦158等17个小麦品种为母本,小麦糯性系安农糯小麦1号为父本,配制组合。在后代群体中鉴定糯性变异材料,研究全糯质籽粒的分离比例,并进一步选育糯小麦品种(系)。讨论了糯小麦产量和农艺性状改良及其利用等问题。

Seventeen released wheat varieties, including Wanmai 18, Yangmai 158 and others, were selected as female and Annong Waxy Wheat-1, a waxy wheat line, was selected as male parent material. Seventeen wheat crosses were formed. The waxy mutant materials were identified in the early generations, the separating rate of whole waxy wheat kernels were analyzed. The waxy wheat varieties or lines were used for further steps to breed. The improvement and utilization of yield and agronomic traits were discussed.
