Dissecting genetic loci of yield, yield components, and protein content in bread wheat nested association mapping population
Euphytica - Tập 219 - Trang 1-15 - 2023
In the last century wheat breeding programs have shown consistent yield increases, often associated with lower grain protein concentrations (GPC). A better understanding of the genetic basis of grain yield and grain protein content can help break the grain yield—GPC negative correlation. We developed a nested association mapping population composing a set of spring wheat genotypes for genetic diss......
Phenotypic, genotypic and environmental correlation in tomato (Lycopersicon esculentum)
Euphytica - Tập 31 - Trang 151-159 - 1982
Twelve inbred lines of tomato and their 132 hybrids (reciprocals were considered separately) were studied in four environments: glasshouse and open air, with and without plastic cover. Nine characters were recorded and the phenotypic and environmental correlations between them were obtained within environments and for the complete set of data. Characters showing the highest phenotypic correlation ......
Metabolism, seedling growth and nucleolar activity in germinating diploid wheat Triticum monococcum ssp. monococcum cv. Einkorn
Euphytica - Tập 124 - Trang 47-54 - 2002
Seed germination, seedling growth, mitotic and nucleolar activity were investigated as indicators of metabolic activity in a diploid wheat, Triticum monococcum ssp. monococcum cv. Einkorn. Two developmental phases were identified, an initial lag phase during which reactivation of NOR's and the initiation of mitotic activity (10 h) took place prior to the appearance of the primary root (16 h). Domi......
Pattern of variation for seed size traits and molecular markers in Italian germplasm of Phaseolus coccineus L.
Euphytica - Tập 157 - Trang 69-82 - 2007
Variation in Italian germplasm of Phaseolus coccineus L. was assessed for seed traits and molecular markers. A total of 130 seeds and seedlings, five for each of 21 Italian landraces, an Italian commercial cultivar and four Mesoamerican landraces of P. coccineus, were analysed using seven selected PCR markers: three RAPDs, two ISSRs and two ETs. Seed weight of the Mesoamerican landraces was ≤1 g, ......
Microsatellite Marker Identification of a Triticum Aestivum -Aegilops Umbellulata Substitution Line with Powdery Mildew Resistance
Euphytica - Tập 150 - Trang 149-153 - 2006
Aegilops umbellulata acc. Y39 and Triticum carthlicum acc. PS5, immune to many powdery mildew isolates, were crossed to make an amphidiploid line Am9. The powdery mildew resistance of Am9 was transferred to common wheat cultivar Laizhou953 by crossing and backcrossing. In this study, the origin of powdery mildew resistance in a BC3F4:5 population derived from a cross of Am9 and La......
Notes on species delimination, species relationships and polyploidy in Avena L.
Euphytica - Tập 20 - Trang 380-395 - 1971
On the combined evidence from morphology, ecology, and cytogenetics, seven species are recognized in the genus Avena L. 1. A. clauda
Dur., 2. A. ventricosa
Bal. 3. A. longiglumis
Dur, 4. A. strigosa
Schreb., 5. A. magna
Murphy et Terr., 6. A. murphyi
Ladiz. and 7. A. sativa L. The first three species are wild diploids. The fourth is a diploid-tetraploid complex of wild forms, weeds and cultivars. ......
