Streszczenie:

Presently auto-octoploidy has been induced in an induced auto-tetraploid som, Persea bombycina (2n=24), the principal food plant of muga silkworm (Antheraea assamensis Helfer), through colchicine treatment (0.5%). Auto-octoploids showed deterioration in almost all the morphological features in contrast to tetraploid which seem to be the optimum ploidy level. Auto–octoploid is highly susceptible to stem diseases and dwarf in growth nature.

Streszczenie:

Fragaria species from the center of diversity have not been integrated into octoploid commercial strawberry cultivars because of ploidy level differences. Even though traits such as disease resistance, enhanced flavor, cold hardiness, and vigor are known to exist in the diploid, tetraploid, and hexaploid species, they cannot be easily used for breeding. The synthetic octoploid method circumvented introgression difficulties by combining lower ploidy species and doubling to the octoploid level. Although easily crossed to cultivars, the use of synthetic octoploids has been minimal as it has been

Polyploidization has played a crucial role in plant breeding and crop improvement. However, studies on the polyploidization of tropical tree species are still very scarce in this region.

N. cadamba belongs to the Rubiaceae family is a natural tetraploid plant with 44 chromosomes (2n = 4x = 44).

As the product of interspecific hybridization between its two ancestral octoploid (2n = 8x = 56) species (Fragaria chiloensis and F. virginiana), the cultivated strawberry (F. ×ananassa) is among the most genomically complex of crop plants, harboring subgenomic components derived from as many as four different diploid ancestors. To physically visualize the octoploids’ subgenome composition(s), we launched molecular cytogenetic studies using genomic in situ hybridization (GISH), comparative GISH (cGISH), and rDNA-FISH techniques. First, GISH resolution in Fragaria was tested by using diploid an

Polyploids of many species of horticultural plants are widely used in breeding programs since they are characterized by vigorous growth, larger organs, and greater resistance to biotic and abiotic stress. Saskatoon berry (Amelanchier alnifolia Nutt.) is in a form of diploid (2n = 2x = 34) and tetraploid. So far, no reports on induction of polyploidy in this species have been found. The aim of the study was to obtain Saskatoon berry octoploids with the use of in vitro shoot cultures. Shoots of the tetraploid of Canadian cultivars ‘Martin’ and ‘Smoky’ derived from in vitro cultures were used for

Thinopyrum intermedium (2n = 42) is a source of many potentially useful genes for wheat improvement. Many partial amphiploids have been produced between Th. intermedium and Triticum aestivum that are fertile and stable. These partial amphiploids all have 56 chromosomes, including seven pairs of chromosomes from Th. intermedium. To explore the genomic composition of these lines, meiotic analysis was conducted on 32 hybrid combinations between eight different partial amphiploids. All but two of the chosen parents were distinguishable on the basis of perenniality, head morphology, and reactions t

Abstract Background and Aims Cardamine occulta (Brassicaceae) is an octoploid weedy species (2n = 8x = 64) originated in Eastern Asia. It has been introduced to other continents including Europe and considered to be an invasive species. Despite its wide distribution, the polyploid origin of C. occulta remained unexplored. The feasibility of comparative chromosome painting (CCP) in crucifers allowed us to elucidate the origin and genome evolution in Cardamine species. We aimed to investigate the genome structure of C. occulta in comparison with its tetraploid (2n = 4x = 32, C. kokaiensis and C.

Chromosome pairing in the amphiploid (8x) of 4x Bromus pumpellianus ssp. dicksonii × 4x B. inermis was compared with pairing in the F1 hybrids between natural octoploid cytotypes of B. inermis and B. pumpellianus and the octoploid parents. Predominantly bivalent pairing was found in both the amphioctoploid, octoploid F1 hybrids, and octoploid parents. Bivalent formation in the amphioctoploid could be based on chromosome differentiation between the tetraploid cytotypes of B. inermis and B. pumpellianus. These results suggest that the evolution of the octoploid cytotypes of B. inermis and B. pum

Octoploid strawberry (Fragaria ×ananassa) is a valuable specialty crop, but profitable production and availability are threatened by many pathogens. Efforts to identify and introgress useful disease resistance genes (R-genes) in breeding programs are complicated by strawberry’s complex octoploid genome. Recently-developed resources in strawberry, including a complete octoploid reference genome and high-resolution octoploid genotyping, enable new analyses in strawberry disease resistance genetics.

Among the Fragaria species, the cultivated strawberry Fragaria × ananassa (2n=8x=56) is the most economically valuable crops. After harvest, they are extremely perishable, have a short shelf life, and are susceptible to mechanical injuries and physiological decay due to loss of tissue integrity, sensitivity to fungal diseases, and have a large surface area, which lacks an outer protective rind. Therefore, maintaining high nutritional values in the berry fruit whilst maintaining high fruit quality requires an understanding of the genetic and environmental effects on each trait, and how differen

Repeated polyploidization events are thought to be among the most important causes of sympatric speciation throughout evolutionary time. Changes in phenology and trait expressions that arise in polyploids have been shown to affect plant interactions with insect herbivores and pollinators. If these interactions are changed, selection subsequent to the polyploidization event could contribute to further divergence, or increased similarity, of cytotypes. This study was conducted to investigate plant interactions with insect herbivores and pollinators and patterns of selection in tetraploid and oct

The cultivated strawberry (Fragaria × ananassa Duch.) is the third most economically important fruit crop.

To overcome these challenges, plant breeders aim to improve upon existing cultivars and to release new ones with higher yield, better fruit quality and more disease resistance.

The species of Fragaria are commonly known as strawberries. The genus is found in the temperate regions of the northern hemisphere as well as South America. The most extensively distributed species in the genus is F. vesca L. and the commonly cultivated strawberry is F. x ananassa Duch.
