1988～1991连续四年在黑龙江省对小麦K、Ven型不育系的回交转育,打破了黑龙江省春麦区只有“T”型胞质不育的局面.实现了新“三系”配套,开拓了小麦杂种优势“多胞质”利用的前景;经测恢表明:黑龙江春麦对新型不育系一般都有恢复能力,但品种间有差异,初测恢复度变化在52％～93％之间。说明K、Ven型新不育系具有恢复源广的特点。新“三系”的配套、为进一步研究打下了基础。
The backcrossing of wheat K and Ven type sterile lines in Heilongjiang Province from 1988 to 1991 for four consecutive years broke the situation of only “T” type cytoplasmic male sterility in spring wheat region of Heilongjiang Province. The results showed that: Heilongjiang Chunmai generally has the ability of restoring new CMS lines, but there are some differences between the two varieties. The recovery of the initial test varies from 52% to 93% between. Description K, Ven new male sterile lines with a wide range of recovery characteristics. The new “three lines” package, laid the foundation for further research.
