Sp. tritici of the F1 plants were tested at the seedling and adult stages. The results indicated that dominant and semi-dominant genes were responsible for powdery mildew resistance at the seedling stage, while dominant, semi-dominant and recessive genes were found controlling the powdery mildew resistance at the adult plants. After testing the Pm30 linked SSR marker Xgwml59 on the 40 F1 hybrids between wild emmer and common wheat, it was found that the Pm30 linked Xgwm159 loci could be detected at 8 F1 hybrids, indicating the 8 wild emmers might also carry the Pm30 gene.

The paper induces and analyzes research method of the tooth, including Method line of the tooth theory,Envlopment theory, Camus theory, Circling cluster theory and so on.Based on the past theories,the new measure to deduce the chain wheel tooth equation of roller chain at high speed,Circling cluster and envlopment theory,is proposed by analyzing basic concept of equidistant curve and Willis theory.Following the presentation of drawing lessons from traditional roller chainof the change of stanza line distance. A new type of roller chain at high speed is given in the paper.The paper studies deeply structural characteristics, the change of stanza line distance,separation between plank and bore and so on.According to design requst of roller chain at high speed and the study ofH_y--V_0 tooth chain,the impossibility that Quasi-conjugage engagement theory isrealized by the engagement of roller chain at high speed from the aspect of theory is decribed.
