Genetic analysis were carried out to identify powdery mildew and strip rust resistance genes in the F2 of Am6-4 amphiploid and wheat variety Jinan17. Results showed that resistances to powdery mildew and stripe rust were controlled by a single dominant gene respectively. 124 SSR primers from genome D were used for marker analysis, marker Xgwm98 150(150为下标) from the chromosome 6D was found to be linked to the new powdery mildew resistance gene with a linkage distance 20.42 cM; A special DNA band was amplified by primere xgwm33 in resistant stripe rust plants, resistance gene for stripe rust was localized on chromosome 1D, and the genetic distance between resistance gene and marker is 8.0 cM.

Blood samples from 23 Huacaya alpacas ,3 males and 20 females ,were used to study chromosome karyotype ,so as to provide some effective cytogenetics basis for the selectioiymprovement by crossing and disease diagnosis of alpacas ,and genetic mechanisms of sex determination. Peripheral blood lymphocyte culture was used to prepare chromosome. Methods of trypsase-EDTA and BSG (Barium hydroxide / Saline / Giemsa)were used for G-banding and C-banding respectively . The results showed as follows:Firstly , the number of diploid chromosomes was in the alpacas 2n=74,with the karyotype 74, XY and 74, XX for males and females respectively.
