The indica variety Dular has a high level of resistance to rice stripe virus (RSV). We performed quantitative trait locus (QTL) analysis for RSV resistance using 226 F2 clonal lines at the seedling stage derived from a cross between the susceptible japonica variety Balilla and the resistant indica variety Dular with two evaluation criteria, infection rate(More)
Quantitative trait loci (QTL) for the length of the dehiscence that forms at the base of the anther [basal dehiscence length (BDL)] in rice (Oryza sativa L.) were analyzed using chromosome segment substitution lines (CSSLs) developed from 9311 (as the recipient) and Nipponbare (as the donor). Using composite interval mapping with QTL Icimapping software,(More)
The necessity of developing an automatic high performance exertion system for the type approval test of tank GCS is expounded. The composition and working principle of exertion system are introduced. Studies on exertion security and non-overshot exertion control performance are carried on using simulator and simulation methods, which draw the conclusion(More)
During the test of tank gun control system for type approval, external force is exerted on the gun barrel to measure a specific parameter. The architecture and working principle of exertion system are introduced, analytical calculation of the influence of force point transition on exertion precision is emphasized, the influence of exertion plane's(More)
OBJECTIVE To observe the growth and metastasis effect of interferon alpha-1b (IFN-alpha-1b) on nasopharyngeal carcinoma cell line CNE-2 in xenografted model of mice liver. Comparing rAAV-mediated IFN-alpha-1b gene therapy with the IFN-alpha-1b protein therapy. METHODS The xenografted model of liver nasopharyngeal carcinoma was established by injecting the(More)
