宁夏小麦地方品种(系)和白黑麦的杂交结实率在0~7.1%之间,极显著地低于中国春和中国春ph1b与白黑麦的杂交结实率(47.6%和20.8%)。控制宁夏普通小麦与其近缘属种可交配性的基因可能是Kr1Kr1Kr2Kr2Kr3Kr3和Kr1Kr1Kr2Kr2Kr3Kr3,几乎没有能提高可交配性的隐性基因Kr。
The seed setting rate of Ningxia wheat landraces and white rye was between 0 and 7.1%, which was significantly lower than that of Chinese spring and Chinese spring phlb and white rye (47.6% and 20.8%). The genes that control the copulability of common wheat and its related species in Ningxia may be Kr1Kr1Kr2Kr2Kr3Kr3 and Kr1Kr1Kr2Kr2Kr3Kr3, and there is almost no recessive gene Kr that can improve the mateability.
