3Phenotypic diversity in Ethiopian durum wheat(Triticum turgidum var.durum)landraces显示文摘The phenotypic diversity of 274 Ethiopian durum wheat accessions was analyzed, taking their geographic origins into account. The aim was to assess the extent and patterns of agronomically important phenotypic variation across districts of origin and altitude classes for major qualitative traits using diversity index and multivariate methods. Eight qualitative and three quantitative traits were scored for 2740 plants and analyzed for diversity. The Shannon–Weaver diversity(H′) index was used to estimate phenotypic diversity. The estimated H′ ranged from monomorphic for glume hairiness to highly polymorphic for other traits. The highest(0.86) H′ was obtained for seed degree of shriveling, possibly indicating the differential responses of the genotypes to water deficit during later growth stages. With respect to district of origin, the highest(0.72) and lowest(0.44) H′ values were obtained for the Bale and SNNP districts, respectively. With respect to altitude, the highest(0.76) and lowest(0.62) H′ values were recorded for altitudes 1600–2000and > 3000 m above sea levels, respectively. Principal components analysis explained substantial variation contributed by district of origin and altitude range. Genotypes were clustered into three groups by districts of origin and altitude class, with relatively strong bootstrap values of 57 and 62 for the former and latter, respectively. It could be concluded that Ethiopian durum wheat landraces are very diverse both within and among districts of origin and altitude classes. This wealth of genetic diversity should be exploited for wheat improvement of yield and for resistance to biotic and abiotic stresses, particularly terminal drought.Dejene K.Mengistu Afeworki Y.Kiros Mario E.Pè 2015The Crop Journal2015,3,3:3

5地形跟踪导弹碰地概率的确定显示文摘超低空飞行的飞航导弹、无人驾驶飞机,特别是远程巡航导弹,无论是在海面上空,还是在陆地上空飞行,为了增加飞行器的突防能力,都将尽量压低飞行高度,进行所谓“掠海”或“擦树稍”飞行。对于击水概率或碰地概率的研究是上述飞行器设计中重要课题之一。本文推导了地形跟踪导弹碰地概率的一个计算公式,并将其与以往通常使用的公式进行了比较。E.P Cunningham 雷小龙 1990飞航导弹1990,,2:2
