Inbreeding Depression in the Full-sib Offspring of Populus nigra L.

Increased prenatal maternal investment reduces inbreeding depression in offspring.

Inbreeding depression refers to the reduction of fitness that results from matings between relatives. Evidence for reduced fitness in inbred individuals is widespread, but the strength of inbreeding depression varies widely both within and among taxa. Environmental conditions can mediate this variation in the strength of inbreeding depression, with environmental stress exacerbating the negative...

Parent-Offspring and Full Sib Correlations under a Parent-Offspring Mating System.

Decline in heterozygosity under full-sib and double first-cousin inbreeding in Drosophila melanogaster.

The effects of inbreeding on heterozygosities and reproductive fitness were determined by carrying out full-sib and double first-cousin inbreeding in Drosophila melanogaster populations for up to 18 generations. Parents were scored each generation for five or six polymorphic enzyme loci, and progeny numbers per pair were recorded. Inbreeding depression, in the form of significant reductions in ...

The Effect of Salinity Stress on Full-sib Progeny of Sugar Beet in Field Condition

Considering the effect of salinity stress on the quantitative and qualitative traits of sugar beet genotypes, it seems necessary to study the response of genotypes obtained from breeding programs to salinity stress. For this purpose, 17 full-sib genotypes (derived from sibling crossing) with 7 different tolerant control under two salinity stress (electrical conductivity 17.36 dsm) and without s...

Morphological study of the leaves of two European black poplar (Populus nigra L.) populations in Slovenia

Background and Purpose: Conservation efforts across Europe and a substantial lack of information regarding the present status of black poplar (Populus nigra L.) in Slovenia led us to conduct this research. The objectives were to determine the presence of preserved native black poplar in Slovenia, to evaluate the variation within and between two selected populations, and to evaluate the conditio...
