Analyses of hybrid viability across a hybrid zone between two Alnus species using microsatellites and cpDNA markers.

as a bridge for introgression. The presence of fertile triploids is essential hybrid zone in a study area in southern Serbia, which results in triploid hybrid observations, with selection against triploid hybrids ...

Cytotype coexistence in the field cannot be explained by inter-cytotype hybridization alone: linking experiments and computer simulations in the sexual species Pilosella echioides (Asteraceae)

of relatively high capacity for clonal growth for all cytotypes and especially for triploids.

Spontaneous natural formation of interspecific hybrids within the Festuca-Lolium complex

to the largely sterile triploid forms and their rare sexual progeny. The triploid hybrid F site at 1 000 m altitude, these triploid hybrids grew much more vigorously than at such altitudes in permanent grasslands. The ...

The More the Merrier: Recent Hybridization and Polyploidy in Cardamine

and allopolyploidy in the Swiss Alps. Triploids are typically viewed as bridges between diploids. The genome of the triploid semifertile hybrid Cardamine 3 insueta (2n = 24, RRA) wasshown structurally stable within the

A review on the potential of triploid tench for aquaculture

triploid tench are reviewed. Triploidy is best induced with cold shock; with triploids diploids, if farmed untill post sexual maturity. Triploids exhibit more abdominal fat and less polyunsaturated fatty acids of the n-3 a...

Frequent occurrence of triploid hybrids Festuca pratensis × F. apennina in the Swiss Alps

The occurrence of triploid hybrids in nature is scarce due to the so-called triploid block representing formation of nonviable progeny after mating diploid with tetraploid. Here we describe frequent presence of triploids or...

Difference in blood and water diffusion distance in gill lamellae of diploid and triploid tench Tinca tinca (L.)

Image analysis of sagittal sections of gill lamellae of diploid and triploid mm) to be significantly higher than that of their triploid siblings (1.46 mm; P < 0.01). Lamellae of diploids compared to triploids were found to ...

Analysis of growth, weight and relevant indices of diploid and triploid population of tench (Tinca tinca, Linnaeus 1758).

This study determined biometric and weight parameters and relevant indices of diploid and triploid tench. Altogether 137 siblings of tench were studied. This study brought an evidence for faster somatic growth and bigger final weight of ...

Does triploidization produce functional sterility of triploid males of tench Tinca tinca (L.)?

to develop testis. The reason why sterility levels in triploid fishes differ among of triploid males of tench was studied. Analysis of variance showed an insignificant as on spermatozoa velocity. Experimental crosses between normal...
