Hybridization with introduced genetic resources is commonly practiced in ornamental plant breeding to introgress desired traits. The 19th century was a golden age for rose breeding in France. The objective here was to study the evolution of rose genetic diversity over this period, which included the introduction of Asian genotypes into Europe. A large sample of 1228 garden roses encompassing th...
Everyone who has written upon the subject of cholera has pointed out that however familiar we may be with respect to the characters of the pathogenic organism discovered by Koch in I883, with regard to its pathogenicity the single fact actually known is that the presence of this vibrio in the intestinal mucosa causes the disease. But why do the vibrios undergo modifications in the body? Why do ...
This study investigates the notion of perceptual distance among the Afro-Asiatic family. It is based on a “same/different” task involving French subjects and items from 10 languages or dialects (8 Afro-Asiatic: Amharic, Moroccan Arabic, Jordanian Arabic, Tarifit Berber, Touareg Berber, Hausa, Hebrew, Somali and 2 intruders: Armenian and Turkish). The task was judged very difficult by the subjec...
According to the WHO Multinational Study1) on the vascular complications of diabetes mellitus, the prevalence rates of microvascular complications in diabetic patients were the same both in Asiatic (Japan and Hong Kong) and Western countries, but the rates of cardiovascular complications were far lower in Asiatic than that in Western countries. We had the same result in our study done in the pa...
LOUISE WOOTTON (Department of Biology, Georgian Court University, 900 Lakewood Avenue, Lakewood, NJ 08701). First report of Carex macrocephala in eastern North America with notes on its co-occurrence with Carex kobomugi in New Jersey. Torrey Bot. Soc. 134: 126–134. 2007.—The discovery of three populations of the large-headed sedge, Carex macrocephala, in New Jersey described in this paper, repr...
ILD Gossypium anomalum Wawrs. and Peyr. among Gossypium species whas anomalous petal spot inheritance. Its petal spot involves two independently inherited genes; a ghost spot gene interacts with a spotless gene making a large anthocyanin area at the base of a petal (SILOW 1941). In the two cultivated Asiatic diploid species red petal spot involves three closely linked genesmargin. ghost spot, a...
An experiment was conducted to investigate the heterosis in 12 F1 hybrids of durum wheat using agronomic and morphological traits. Parents were selected according to the estimated genetic distances based on the results of a two-year field experiment, which were then crossed to produce F1 hybrids. Twenty-three genotypes (including 11 parents and 12 hybrids) were evaluated using a randomized co...
