The demand for superior grain quality represents a major issue in rice (Oryza sativa L.) breeding. To study the genetic basis of rice grain quality, including traits specifying grain dimension and percentage of grains with chalkiness, quantitative genetic analysis was conducted in a population of 37 introgression lines (ILs) of indica elite variety Habataki(More)
The study of 1000-grain weight (TGW) and percentage of grains with chalkiness (PGWC) is very important in rice. In this study, a set of introgression lines (ILs), derived from Sasanishiki/Habataki with Sasanishiki as the recurrent parent, were used to detect correlations and quantitative trait loci (QTL) on TGW and PGWC in two different environments.(More)
In this paper, shock initiation experiments on the explosive RDX-8701 were performed to obtain in-situ pressure gauge data for the purpose of determining the critical gap thicknesses. The pressure waves are got by manganin-constantan composite 2-D Lagrange gauge. The process of initiation has been calculated near the critical point by 2-D Lagrangian(More)
Theoretical analysis and numerical calculation of the building structures with impact resistant character depend on the parameters and results of the experiment. The dimensions of the plototype is shrunken to the experimental model. The minification of the dimension and strength is not accordant between the plototype and the experimental model. Usually,the(More)
