On the basis of determining their resistant spectrum, CY21, CY23, CY27, CY29, CY30, CY31, CY32, Su-11, Su-14 were used to investigate the resistant components at seeding stage, such as latent period, infection efficiency, uredinium length, sporulation capacity, period of spore production and severity. Also, two equal weight races' mixture CY27:CY30, CY27:CY31, CY27:CY32, CY31:Su-4, CY30:Su-11 were continued to reproduce six generations of Libellula and Xiannong 4 respectively, and the ration changes of each race were tested.

To explore the possibility that the androgen may facilitate differentiation of hair follicle stem cells into sebocytes, we carried out experiments to test this hypothesis. The concrete steps to carry out this research were as follow: Firstly, observed the expression of AR and examined the expression of AR mRNA of rat vibrissa follicle stem cells in vivo in three defined phases of a hair follicle cycle, including anagen, catagen and telogen. Secondly, cultured HFSC deprived from vibrissa follicle bulge region in culture flasks and observed the expression of AR, ketertin 15 (K15), cluster of differentiation 34 (CD34) andβ1-integrin of those cells.
