Identification of the right parental combinations to maximize heterosis is the major goal of hybrid breeding, which could be achieved through identification of heterotic groups. The main objective of ...
The use of remote sensing data for tree species classification in tropical forests is still a challenging task, due to their high floristic and spectral diversity. In this sense, novel sensors on boar...
Cadmium (Cd) accumulation in rice followed by transfer to the food chain causes severe health problems in humans. Breeding of low Cd accumulation varieties is one of the most economical ways to solve ...
The mycological conditions on study plots established in forests growing on former agricultural farm lands were studied. In young spruce stand (8?0 years) reduced and unstable spectrum of macromycetes...
Sclerotinia homoeocarpa F.T. Bennett, the causal agent associated with dollar spot, is a common and economically challenging turfgrass disease in North America. Acceptable turfgrass quality requires t...
Magnitude of heterosis in F2 and inbreeding depression for different quality traits of five cotton (Gossypium hirsutum) cultivars (TH-3/83, NIAB-78, CIM-109,Mc-Nair-3150 and Reshmi) in F3 generation w...
This study investigated a clonal variations in sprouting times of Allium victorialis L. collected from 28 habitats around Hokkaido, Japan, propagated vegetatively and grown in Sapporo. For comparing c...
The purpose of the study conducted in 2005-2006 in Kruszyn Krajeński near Bydgoszcz was to determine the root mass of millet cultural varieties Gierczyckie and Jagna and the vertical distribution of t...
Studies of yielding and changes of species composition of pasture mixture sward in post-bog habitat (peat-muck and mineral-muck soils) were carried out in 1998-2003. Six pasture mixtures were include...
Twenty eight hybrids, produced from diallel crossing excluding reciprocals among eight parents, were studied along with the parents for combining ability for yield and 17 yield components. The study...
Genetic variability of 10 quality parameters in a set of 56 high yielding diverse rice genotypes was evaluated. Phenotypic and genotypic coefficients of variation revealed the existence of large v...
Defoliation timing affects lint yield and quality of cotton (Gossypium hirsutum L.). A timing method based on heat-unit accumulation was evaluated in replicated field plots in Georgia, Louisiana, Tenn...
Arbuscular mycorrhizae (AM) are benefi cial symbionts for plant growth. They are associated with higher plants by a symbiotic association, and benefi t plants in uptake of phosphorus nutrients, produc...
Fertilising with phosphorus (P) ensures continuous supply of an essential growth factor as necessary for productive and sustainable agriculture. The amounts of P required to attain and maintain an ade...
The native reserves of phosphorus (P) in Finnish soils are sizeable but poorly available to plants. The P status has been generally poor, but large rates of P applied since the 1940s have substantiall...
