1. Genótipos de trigo: características agronômicas em dois locais do estado de São Paulo
A obtenção de cultivares com características agronômicas de interesse tem resultado em significativos incrementos na produção de grãos. Dezoito linhagens de trigo e duas cultivares-controle (IAC-24 e IAC-370) foram avaliadas quanto à produção de grãos, altura das plantas, ao acamamento, comprimento da espiga e aos componentes de produção, em exp

2. Identificação de fontes de resistência à ferrugem da folha do trigo em acessos de Aegilops tauschii
No Brasil, prejuízos ocasionados pela ferrugem da folha do trigo (Puccinia triticina) ocorrem anualmente. A incidência generalizada nas diferentes regiões produtoras varia em intensidade, dependendo das condições climáticas, da resistência genética das cultivares e do controle químico, sendo que a utilização de cultivares resistentes é o método

3. Cytogenetics and immature embryo culture at Embrapa Trigo breeding program: transfer of disease resistance from related species by artificial resynthesis of hexaploid wheat (Triticum aestivum L. em. Thell)
Worldwide wheat (Triticum aestivum L. em. Thell, 2n = 6X = 42, AABBDD) breeding programs aim to reorganize genotypes to achieve better yields, environmental adaptation and food quality. The necessary interdisciplinarity for breeding purposes requires an accurate choice of the most appropriate cellular and/or molecular strategies available to be integrated wi

5. The Molecular Basis of Genetic Diversity among Cytoplasms of Triticum and Aegilops. III. Chloroplast Genomes of the M and Modified M Genome-Carrying Species
The restriction fragment patterns of chloroplast DNAs of all M or modified M genome-carrying Aegilops species, and those of common wheat (Triticum aestivum), Ae. umbellulata and Ae. squarrosa as referants, have been analyzed using eight restriction endonucleases, BamHI, EcoRI, HindIII, KpnI, PstI, SalI, SmaI and XhoI. Nine distinctly different chloroplast

6. Intramolecular recombination of chloroplast genome mediated by short direct-repeat sequences in wheat species.
Structural alterations of the chloroplast genome tend to occur at "hot spots" on the physical map. To clarify the mechanism of mutation of chloroplast genome structure in higher plants, we determined the nucleotide sequence of the hot-spot region of chloroplast DNAs related to length mutations (deletions/insertions) in Triticum (wheat) and Aegilops. From a c

7. Control of Galactosyl Diglycerides in Wheat Endosperm by Group 5 Chromosomes
Lower levels of monogalactosyl diglyceride (MGDG) and digalactosyl diglyceride (DGDG) have been found in tetraploid wheats as compared with those in hexaploid wheats. The same difference has been found between hexaploid cultivars and tetraploid lines derived from them by D genome extraction. A lower level of MGDG and DGDG is also present in Triticum carthlic
