Genetic Study of Resistance to Stripe Rust in Xikemai 6 Adult Plant Stage of Wheat
摘要
Abstract
With wheat stripe rust physiological races CYR31,CYR32 and CYR33,Su11-4 and V26,rules of epidemic resistance and disease resistance genetic of Xikemai 6 to wheat stripe rust are cleared. In March 2015,Xikemai 6 and Mingxian 169 and hybrid progenies F1,F2,F3 of plant inoculation and disease resistant genetic analysis, results showed that the resistance of wheat Xikemai 6 wheat stripe rust CYR31 was controlled by 2 dominant genes and 1 recessive genes;resistance to CYR32 by 3 dominant genes(2 of them showed additive effect)control;resistance to CYR33 is controlled by 1 pairs of dominant genes and 1 recessive genes;resistance to Su11-4 by 1 dominant genes and 1 recessive genes overlapped or independent control of stripe rust resistance;V26 independently controlled by 1 dominant genes. From Xikemai 6 good performance on the test and production,years of disease resistance identification and the study of genetic analysis proved that Xikemai 6 on the wheat stripe rust has good resistance,and the resistance genetic stable is a comprehensive character of excellent germplasm resources and anti-source material. Molecular marker and localization can be further studied in order to make contributions for wheat breeding new stripe rust resistant parent.关键词
