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, ......
Genetic characterization and gene flow in different geographical-distance neighbouring natural populations of wild soybean (Glycine soja Sieb. & Zucc.) and implications for protection from GM soybeans
Euphytica - Tập 186 Số 3 - Trang 817-830 - 2012
Resistance to powdery mildew (Erysiphe graminis f.sp. hordei) in the barley cultivar Galleon. I. Relationship with known genes for resistance
Euphytica - Tập 52 - Trang 1-9 - 1991
A study was undertaken into the nature and number of resistance genes in the barley cultivar Galleon against powdery mildew (Erysiphe graminis f.sp. hordei) and the relationship of this resistance with other known resistance genes. The reactions of F1s, F2s, F3s, and test-cross progenies from crosses of Galleon with three susceptible cultivars (Weeah, Clipper and Sonja) to isolates of the pathogen......
A varietal improvement programme on maize in Nigeria
Euphytica - Tập 10 - Trang 294-300 - 1961
A great number of maize varieties introduced from central American areas were tested for yield in Nigeria. A “bulk” variety composed from ten “Trinidad” varieties was grown in trials all over Nigeria and later chosen as source for an improvement programme, using the topcross method and intercrossing the best lines to produce a synthetic variety. The synthetic was ultimately composed from nine ear ......
Response of white clover genotypes to evaluation environments of dense and spaced planting, and implications for selection
Euphytica - Tập 111 - Trang 111-120 - 2000
Twelve genotypes were grown for two years asmonocultures in the evaluation environments (EE) ofspaced planting (SP) and dense planting (DP). Drymatter (DM) yield, seed yield and their contributingtraits were recorded. The environments were comparedfor: i) genotype performance, and selection efficiencyfor the target environment of DP, and ii) estimates ofgenetic correlations between traits. DP was ......
