利用西藏半野生小麦培育新不育类型的研究

本研究以西藏半野生小麦为母本,普通小麦06186为父本杂交,再从 F_1中选不育度高的单株为母本,用06186连续回交四次,育成了西藏半野生小走不育系。用 T 型恢复系和普通小麦对其测交,结果表明原恢3号、L-344/5-4等 T 型恢复系对西藏半野生小麦不育系表现较高而稳定的恢复力;普通小麦成矮一号、昌交7222-5-5-9和多年生小麦对西藏半野生小麦表现不同程度的恢复。我们认为西藏丰野生小麦不育系可能成为一种有利用价值的新不育类型。

STUDIES ON DEVELOPMENT OF A NEW STERILE TYPE OF WHEAT USING TIBET SEMIWILD WHEAT

The study shows that the hybrids between Tibet semiwild wheat as the female parent and the common wheat 06180 as the male parent,and then used the high sterile single plant selected from F_1 as the female parent,common wheat 06186 was backerossed successively four times,Tibet semiwild wheat sterile lines have been bred.T-type restoring lines and common wheat were testcrossed,Yuanhui No.3,L-344/5-4 etc.discovered showed high and steady restoring ability to Tibet semiwild wheat.Common wheat Xianai No.1,Chaagj...
