A Review of Larry Hamberlin\u27s Tin Pan Opera: Operatic Novelty Songs in the Ragtime Era
No full textIn Tin Pan Opera author Larry Hamberlin explores the influence of opera on American popular musical culture in the early twentieth century and its importance in American culture at the time. The author discusses the power dynamic present between America and Europe, and how the use of opera in American popular culture portrays this dynamic. Through evidence found in popular song, Hamberlin tracks the changing position of opera in American society, consequently also tracking the changing cultural and social dynamics of a nation.
New Sources of Resistance in Vicia faba to Chocolate Spot Caused by Botrytis fabae
No full textA two-cycle screening technique was used to evaluate 253 faba bean germ plasm accessions for resistance to chocolate spot. In the first cycle in 1985, faba bean accessions were exposed to a mixture of 20 isolates of Botrytis fabae collected from a wide range of naturally infected leaves of local susceptible cultivars grown in major faba bean production regions in Syria. Some of the resistant accessions detected in 1985 developed a few coalesced sporulating lesions. To subject resistant materials to a rigorous evaluation, 20 isolates of B. fabae obtained from such lesions were used in a second screening cycle in 1986 to inoculate progenies of the resistant accessions detected the previous season. Of the 253 accessions, 14 new, potentially useful sources of resistance to a wide range of isolates of the pathogen were identified
Resistance in Vicia faba Germ Plasm to Blight Caused by Ascochyta fabae
No full textOf the 672 germ plasm lines evaluated in 1980 and 1981 for resistance to Ascochyta fabae in Syria, 19 were resistant and 653 were susceptible. Resistant lines were tested again in Syria, England, Canada, Poland, France, and Tunisia in 1983, 1984, and 1985. Lines BPL 471, 460, 646, 74, and 2485 were resistant at all locations, whereas lines BPL 472, 818, and ILB 1814 were resistant at some, but not all, locations. BPL 471 and 2485 revealed no differential host-pathogen interactions, whereas BPL 818 and ILB 1814 consistently showed significant differential interactions when inoculated with eight isolates of the pathogen from Syria. Therefore, BPL 471 and 2485 seemed to carry genes for a broad-based general resistance compared with those for a narrow-based specific resistance of BPL 818 and ILB 1814. Based on their interactions on BPL 818 and ILB 1814, the eight isolates of A. fabae were classified into four groups representing races 1, 2, 3, and 4
Genetic diversity and taxonomic relationships within the genus Lens as revealed by allozyme polymorphism
No full textA survey of allozyme polymorphism at 11 loci was carried out on 439 accessions from the genus Lens. This comprised 153 Lens culinaris subsp. orientalis, 35 L. odemensis, 117 L. ervoides, 32 L. nigricans, 2 of a differentiated cytotype of L. nigricans and 100 landrace accessions of the cultivated lentil (L. culinaris subsp. culinaris), from 10 different countries. The aim of the survey was to determine intra-specific genetic diversity and species relationships, based on phylogenetic and phenetic analyses, particularly regarding the position of L. odemensis and the differentiated cytotype of L. nigricans. Diversity was described by three statistics. The level of diversity in the cultivated taxon was lower than in any of the wild species according to two of these statistics, the percentage of polymorphic loci and mean number of alleles per locus. For the third measure (Nei's mean genetic diversity) it was only greater than L. ervoides. Genetic diversity statistics of the wild species indicated differences in the nature of between-population genetic diversity within the different taxa. Phylogenetic analysis suggests that L. odemensis and L. ervoides evolved from a common ancestor, and L. culinaris subsp. orientalis subsequently evolved from L. odemensis. Phenetic analysis, however, places L. odemensis closer to L. culinaris subsp. orientalis than to L. ervoides. Nei's mean genetic distance of L. odemensis from both L. culinaris subsp. culinaris (0.204) and L. culinaris subsp. orientalis (0.110) was greater than the distance between them (0.062). This evidence is not conclusive in determining whether L. odemensis should retain its specific status. Further crossability studies should be carried out on a range of genotypes to assess the potential for gene flow. The evidence presented shows the differentiated cytotype of L. nigricans to be quite distinct from other L. nigricans accessions, both phenetically and phylogenetically. This indicates that the differentiated cytotype of L. nigricans may constitute a new taxon. Discriminant function analysis reveals that isozymes may be useful in validating species classification
Protein content variation in a pure line faba bean (Vicia faba) collection
No full textA set of 840 pure line faba beans (Vicia faba L) derived by a process of cyclic single plant selection from 1979 to 1985 was used for this study. Mean content of protein was 240 g kg−1 with a standard deviation of 18 g kg−1 and a range of 180 to 310 g kg−1. For eight subregional groups (Nile Valley, West Asia, Northern Europe, Southern Europe, Eastern Europe, North Africa, Ethiopia and the Indian subcontinent) and for a large and small grouping, the means and ranges of protein content were similar. There were no significant correlations between protein content and seed yield or its components. This resulted in a strong correlation (significant at P < 0.01) between seed yield and protein yield (r = 0‐98), supporting the hypothesis that the optimal way to increase sustainable protein yield per hectare is to increase and stabilise seed yield
