Interand intraspecific crossbreeding experiments were conducted to evaluate the aquaculture potential of hybrids in the genus Dicentrarchus, focusing on fertilisation and hatching success. The experimental design consisted of 24 controlled crosses in which individual and pooled fertilisations were made between wild D. labrax individuals (8 dams and 5 sires originating from West Mediterranean an...

Homoeologous metaphase I (MI) associations in hybrids between durum wheat and its wild allotetraploid relatives Aegilops neglecta, Ae. triuncialis and Ae. ventricosa have been characterized by a genomic in situ hybridization procedure that allows simultaneous discrimination of A, B and wild species genomes. Earlier results in equivalent hybrids with the wild species Ae. cylindrica and Ae. genic...

Sugarcane (Saccharum interspecific hybrids) is the main source of sugar in world. It grown more than 90 countries tropical and subtropical regions. Cultivation techniques production challenges vary by location. This document discusses character- istics sugarcane crop pests affecting its Florida, which largest producer United States

The objective of this paper is to investigate the technological usefulness of selected industrial wine yeasts Saccharomyces cerevisiae and Saccharomyces bayanus and their intraand interspecific hybrids responsible for excessively acidic musts. The stability of yeast fermentation profiles in apple musts was assessed after 90–170 generations, following previous subculturing under aerobic or anaer...

To accelerate domestication of Miscanthus, an important energy crop, 244 replicated genotypes, including two different species and their hybrids, were analysed for morphological traits and biomass yield over three growing seasons following an establishment phase of 2 years in the largest Miscanthus diversity trial described to date. Stem and leaf traits were selected that contributed both direc...

ENE duplication is an important evolutionary mechanism and may have led to large increases in genome size and diversity early in vertebrate evolution (OHNO 1970). The role of duplicate genes may be further elucidated by biochemical and genetic analyses of multigenic isozyme system in modern teleosts. Gene duplications are generally detected by the biochemical multiplicity of gene products. Appa...

Marmur, J. (Brandeis University, Waltham, Mass.), E. Seaman, and J. Levine. Interspecific transformation in Bacillus. J. Bacteriol. 85:461-467. 1963.-Deoxyribonucleic acids (DNA) from various species of the taxonomic group Bacillaceae were examined for base composition, ability to carry out interspecific transformation, and formation of molecular hybrids in vitro. The minimal requirement for ge...

Three accessions of Brachiaria brizantha, three of B. humidicola, and two interspecific hybrids between B. ruziziensis and B. brizantha were analyzed with regard to their mitotic behavior in root tips. All these genotypes revealed chromosome elimination or lack of chromosome affinity in previous analyses of microsporogenesis. Analyses of root tips showed a normal mitotic division in all accessi...

Hybrids have been made between species of Flaveria exhibiting varying levels of C(4) photosynthesis. The degree of C(4) photosynthesis expressed in four interspecific hybrids (Flaveria trinervia [C(4)] x F. linearis [C(3)-C(4)], F. brownii [C(4)-like] x F. linearis, and two three-species hybrids from F. trinervia x [F. brownii x F. linearis]) was estimated by inhibiting phosphoenolpyruvate carb...
