Item Assessment of Resistance to PVY in Interspecific Hybrids Obtained by Combining Type va Resistance from Nicotiana tabacum with the Resistance from PVY-Immune Species Nicotiana africana(MDPI, 2024) Depta, Anna; Doroszewska, Teresa; Berbeć, ApoloniuszTobacco veinal necrosis caused by the potato virus Y (PVY) substantially affects yields and crop quality of tobacco. PVY shows high variability in virulence due to numerous mutations and recombinations. The types of resistance available for tobacco include the va type, effective against some PVY isolates but succumbing to others, and the Nicotiana africana-derived type, fully effective in its native genetic milieu but limited to varying degrees of tolerance when transferred to N. tabacum. The objective of this study was to evaluate the pyramiding potential of these two sources of resistance in alloploid hybrids of Nicotiana tabacum x N. africana. To this end, amphidiploids involving N. tabacum cvs. VAM andWi ślica, each being the carrier of a different variant of the va gene, were created and advanced from F1 to two subsequent selfed generations and to BC1 generation with either VAM or Wiślica as the recurrent N. tabacum parent. The hybrid populations thus produced were challenged with two PVY necrotic isolates, IUNG 23 and IUNG 20, mild and severe isolate belonging to the PVYN-Wi and PVYNTN groups, respectively. The mild isolate failed to infect any of the hybrids or parental species. The hybrids varied in their response to IUNG 20. The F1 and F2 populations were composed of asymptomatic hosts to PVY and of those showing mild vein clearing but no necrotic plants. There was a progressive increase in ability to resist PVY in successive amphidiploid generations, with 30 and 10% of fully resistant plants appearing in the F3 amphidiploids involving VAM and Wiślica. Further research is needed to account for the appearance of segregants completely resistant to PVY, since neither N. africana factor is fully expressed in N. tabacum, nor do the va alleles confer resistance against PVYNTN isolates.Item Charakterystyka i występowanie wirusa Y ziemniaka (PVY) sprawcy brunatnej nekrozy nerwów tytoniu(Instytut Uprawy Nawożenia i Gleboznawstwa Państwowy Instytut Badawczy, 2008) Doroszewska, TeresaItem Development and cytometric evaluation of interspecific F1 hybrids Nicotiana tabacum × N. africana(Instytut Uprawy Nawożenia i Gleboznawstwa – Państwowy Instytut Badawczy w Puławach) Depta, Anna; Doroszewska, TeresaItem DIVERSIFICATION OF DEFENSE RESPONSE TO POTATO VIRUS Y AMONG ALLOPLASMIC TOBACCO FORMS(Instytut Uprawy Nawożenia i Gleboznawstwa – Państwowy Instytut Badawczy w Puławach) Czubacka, Anna; Depta, Anna; Doroszewska, TeresaItem DIVERSIFICATION OF RESISTANCE RESPONSE OF SELECTED TOBACCO CULTIVARS (NICOTIANA TABACUM) DEPENDING ON THE USED POTATO VIRUS Y ISOLATES(Instytut Uprawy Nawożenia i Gleboznawstwa – Państwowy Instytut Badawczy w Puławach, 2020) Depta, Anna; Doroszewska, Teresa; Czubacka, AnnaItem Diversity of Nicotiana species(Instytut Uprawy Nawożenia i Gleboznawstwa – Państwowy Instytut Badawczy w Puławach, 2023) Depta, Anna; Doroszewska, TeresaItem Importance and maintenance of Nicotiana genetic resources(Instytut Uprawy Nawożenia i Gleboznawstwa - Państwowy Instytut Badawczy w Puławach, 2024) Agacka-Mołdoch, Monika; Doroszewska, TeresaThe collection and maintenance of genetic resources of plants is the basis for protecting biodiversity of sources of genetic variation used in breeding. Genebanks collect and store plant material in a viable state and also conduct its evaluation. The most critical factor in maintaining viability is assessing the germination capacity of seeds, which depends on the plant species as well as on the conditions and duration of seed storage. The rate of viability loss varies between species but always increases with seed age. Reduced germination capacity indicates the need for seed regeneration of stored samples. Understanding the period during which seeds of a given species remain viable under specific storage conditions allows for optimizing the regeneration of samples in the collection. This study presents data on seed viability of species of the genus Nicotiana under different storage conditions. They indicate the significant influence of air temperature, seed humidity and oxygen content in the air on long-term seed storage. The aim of this study was to present information on the conservation of genetic resources of the Nicotiana genus from different countries and their potential utilization in breeding programs. Many species of the Nicotiana genus are a valuable sources of resistance to viral, bacterial, and fungal diseases, as well as pests. Numerous resistance traits have been successfully transferred to cultivated tobacco (N. tabacum), frequently resulting in the development of new valuable varieties and breeding materials.Item Influence of Weather Conditions and the Aphid Population on the Potato Virus Y Infection of Tobacco in the Field(MDPI, 2024) Przybyś, Marcin; Doroszewska, Teresa; Doroszewski, Andrzej; Erlichowski, TomaszPotato virus Y (PVY) is a major tobacco (Nicotiana tabacum L.) pathogen that causes severe crop losses. We studied the influence of meteorological factors and a population of twelve aphid species on the development of PVY in field-grown tobacco from 1996 to 2010 in Poland. Three PVY-susceptible tobacco varieties were used in the study. The mean virus incidence ranged from 18% in 2010 to almost 99% in 1996, 2004, and 2009. For determining the relationship between tobacco plant infection and meteorological conditions and aphid populations, logistic regression analysis was used. It was found that the probability of PVY infection is significantly dependent on the average air temperature, relative humidity, number of days with an average temperature of at least 25 ◦C, and the abundance of Aphis fabae and Brachycaudus helichrysi. The probability of infection of tobacco plants with potato virus Y decreased with increasing air temperature and relative humidity. In addition, with each subsequent day with a temperature of at least 25 ◦C, the risk of infection decreased by 24%. Furthermore, it was often observed that high populations of Aphis fabae and Brachycaudus helichrysi were associated with a high incidence of virus infection in tobacco plants.Item Inheritance of Potato virus Y tolerance introgressed from Nicotiana africana to cultivated tobacco(Instytut Uprawy Nawożenia i Gleboznawstwa – Państwowy Instytut Badawczy w Puławach) Korbecka-Glinka, Grażyna; Czubacka, Anna; Depta, Anna; Doroszewska, TeresaItem Jubileusz 160-lecia nauk rolniczych w Puławach – Wiesław Oleszek, Teresa Doroszewska, Mariusz Matyka, Stanisław Krasowicz(Instytut Uprawy Nawożenia i Gleboznawstwa – Państwowy Instytut Badawczy w Puławach) Oleszek, Wiesław; Doroszewska, Teresa; Matyka, Mariusz; Krasowicz, StanisławItem Metodyka integrowanej ochrony tytoniu(Instytut Uprawy Nawożenia i Gleboznawstwa Państwowy Instytut Badawczy) Doroszewska, Teresa; Berbeć, ApoloniuszItem Morphological characteristics of the interspecific FI hybrids Nicotiana tabacum L. x Nicotiana africana Merxm(Instytut Uprawy Nawożenia i Gleboznawstwa – Państwowy Instytut Badawczy w Puławach, 2008) Doroszewska, TeresaItem Nowoczesne metody i techniki w ulepszaniu genotypów tytoniu dla produkcji rolniczej i poprawy jakości surowca(Instytut Uprawy Nawożenia i Gleboznawstwa Państwowy Instytut Badawczy, 2012) Depta, Anna; Kawka, Magdalena; Kursa, Karolina; Doroszewska, TeresaItem Ocena odporności odmian i linii hodowlanych tytoniu na wirusa Y ziemniaka (PVY)(Instytut Uprawy Nawożenia i Gleboznawstwa Państwowy Instytut Badawczy, 2008) Doroszewska, Teresa; Czubacka, AnnaItem Possibilities of using Nicotiana species in breeding for virus resistance(Instytut Uprawy Nawożenia i Gleboznawstwa – Państwowy Instytut Badawczy w Puławach, 2023) Depta, Anna; Doroszewska, Teresa; Czubacka, AnnaItem Stan aktualny i perspektywy uprawy tytoniu w Polsce(Instytut Uprawy Nawożenia i Gleboznawstwa Państwowy Instytut Badawczy, 2009) Doroszewska, TeresaItem Uprawa tytoniu w Polsce - aktualne uwarunkowania agronomiczne i organizacyjno-ekonomiczne(Instytut Uprawy Nawożenia i Gleboznawstwa Państwowy Instytut Badawczy, 2015) Laskowska, Dorota; Doroszewska, TeresaItem Uzyskiwanie zdrowych sadzonek chmielu jako element restrukturyzacji odmianowej(Instytut Uprawy Nawożenia i Gleboznawstwa Państwowy Instytut Badawczy, 2008) Doroszewska, Teresa; Skomra, Urszula; Przybyś, Marcin; Czubacka, Anna; Grudzińska-Sterno, Magdalena
