Fungi occurred on cultivars of genus Pisum

The paper presents the main results and conclusions of 16 cultivars of Lithuanian origin belonging to Pisum genus, of family Fabaceae made of field collections at the the Botanical Garden of Vilnius University during 2000–2006. Disease-causing agents were found on above-ground parts. A total of 16 fungal taxa were identified. The most common genera included Alternaria, Botrytis, Cladosporium, Erysiphe and Fusarium. The most pathogenic fungi were found on Pisum cultivars: ‚Delta‘, ‚Erbi‘, ‚Grafila‘, ‚IP-5‘, ‚Neosypajuščijsia 500‘, ‚Perla‘ and ‚Profi‘. Fungi of genera Alternaria, Botrytis, Cladosporium, Fusarium were commonly found on follicles, Erysiphe – on leaves. Rots caused by Botrytis cinerea, Thielaviopsis basicola and Fusarium genus fungi usually occur under prolonged periods of low air and soil temperatures and high relative humidity. Prolonged periods of high air temperature and high relative humidity are favourable for the occurrence of powdery mildews Erysiphe pisi and leaf spots caused by Ascochyta pisi and Alternaria phaseolicola. It has been concluded, that some cultivars: ‚Greitieji‘, ‚Rainiai‘ of the Pisum plants are quite resistant to the fungal diseases

Paprastosios avietės (Rubus idaeus L.) lauko kolekcijos įvertinimas

A natural diversity of wild raspberry (Rubus idaeus L.) with the stress on fruit and related properties of the species was studied in the field collection established in the Botanical Garden of Vilnius University. 49 accessions were taken for the evaluation purposes in the collection established from wild-collected vegetative plant material covering nearly all parts of Lithuania. The properties assessed were fruit weight, number of drupelets, fruit length and width, floricane height and diameter, flower diameter. The most distinguishing accessions were selected and correlations between some characters established

Barley genetic resources: economic characteristics of hybrids collection

Nustatyta 17 miežių hibridų ir jų tėvinių formų produktyvumas, grybinių ligų intensyvumas ir dažnumas. Tirtos grybinės ligos yra tinkliškoji dryžligė (sukėlėjas Drechslera teres (Sacc.) Shoem.) ir miltligė (sukėlėjas Blumeria graminis (DC.) Speer). Grybinės ligos plito, priklausomai nuo meteorologinių sąlygų. 2005 – 2006 m. nebuvo palankūs šioms ligoms plisti. Hibridai buvo atsparesni grybinėms ligoms, derlingesni negu jų tėvinės formos tw, Hiproly ir Hassan nutans.Grain productivity of barley hybrids and their parental forms was studied as well as intensity and frequency of fungal diseases. The fungal diseases studied were net blotch, disease agent Drechslera teres (Sacc.) Shoem. and powdery mildew, disease agent Blumeria graminis (DC.) Speer. The spread of infections depended on meteorological conditions, while the study years 2005-2006 were relatively dry and not favourable for the diseases. It was observed that hybrids were less susceptible to the diseases and more productive then their parental forms tw, Hiproly and Hassan nutans

Микромицеты надземной части разных сортов семейства бобовых (Fabaceae)

The paper presents the main results and conclusions on 47 cultivars of Lithuanian origin belonging to eight species (Lupinus angustifolius, L. luteus, Lotus corniculatus, Onobrychis, P.arvence, P. sativum,V. faba, V. sativa) plants of five genera (Lupinus L., Lotus L., Pisum L., Onobrychis Mill., vicia L.) of the family Fabaceae in the field collections at the Botanical garden of Vilnius University during 2000-2006. Disease - causing agents were found on above ground parts. A total of 27 fungal taxa were identified. The most common genera included Alternaria, ..Botrytis, Cladosporium, Erysiphe, Fusarium. Most severely injured plants: Lupinus cultivars: 'Augiai','Trakiai', 'Snaigiai', 'Vilčiai', and , 1688, Pisum cultivars : 'Baltieji', 'Delta', 'Erbi', 'Grafila', IP-5, 'Neosypajuščijsia 500', 'Perla','Profi', 'Sobel', 'Žalsviai', 'Ilgiai', Vicia faba 'Ada', 'Aušra', 'Ukko', V. sativa cultivars 'Baltasėkliai'. Outbreaks of other fungal diseases of Fabaceae are more dependent on various environmental conditions. Rots caused by Botrytis, Cylindrocarpon Fusarium, Thielaviopsis genera fungi usually occur under prolonged periods of low air and soil temperatures and a high relative humidity. Prolonged periods of a high air temperature and high relative humidity are favourable for the occurence of powdery mildews and leaf spots caused by Ascochyta, Septoria, Uromyces genera fungi. Some plants (e.g., Vicia faba) are susceptible to leaf spots caused by Botrytis fabae independently of the climatic conditions. It has been concluded that some cultivars of leguminous plants are quite resistant to fungal diseases. Those include Lupinus 'Derliai', 1612, 1666, 1669, 1684, 1686, 3170, 3179, Pisum 'Greitieji', 'Rainiai', and Lotus corniculatus 'Neris'
