The importance of The Sweet Basil (Ocimum basilicum L.) as medical, ornamental and spice plant is well known from ancient times. It`s origin is in Africa and Asia. In the regions with moderate climate are grown more than 150 varieties. The aim of this study is describing and classifying the Basil accessions in the collection of IPGR - Sadovo with the view of their practical use. The experiment is carried out in the experimental field of PGRI - Sadovo during the period 2011-2012. The following biometric indices are reported: Plant - height, width, number of branches, stem - length and diameter; branching first order - length and diameter; leaf - length and width; inflorescence - diameter, height and color; type of inflorescence. Phenological observations were made and the following inter-phase periods are recorded: Sowing, germination, sprouting, blossoming, flowering period, growing season. The results shows that accessions A7E0284, which is with longest flowering and growing periods, very well-leaved and long inflorescence is very suitable for ornamental purposes and in home gardens. Accession A9E0452, which is with maximum number of branches, consequently with maximum leaf mass is most suitable for spice and medical purposes. Hierarchical cluster analysis based on intergroup connections is used to determine the homogeneous groups was made. Thus the accessions are divided into groups (clusters) based on a study of 16 indices. The comparative cluster analysis of Basil accessions in the collection of IPGR - Sadovo shows complete uniformity in the results for the grouping based on morphological parameters and using cluster analysis.

The paper treats the botanical positions of the new fruit groups of the commercial categories plumcots, pluots and aprium. An appropriate proposal was made for giving concrete taxonomic names and assigning the separate groups of plum-apricot hybrids to concrete systematic ranks. Adopting the results of the analyses by botanists and geneticists will determine and fix the concrete interspecific origin of the hybrids. The phonetically substantiated names of the new botanical species obviously show which of the parent species is positioned as a father parent and which as a mother parent. Thus the plum and the apricot species participating directly in hybridization are specified. It is logical to form the Latin name of each new taxon, rendering an account of the harmonious phonetic sounding, by blending syllables of the mother taxon first, followed by a part of the Latin name of the father taxon, e.g., Armeniaca × Domestica - Armestica.

The pollen of the wild species from the genus Crocus L., spread in Bulgaria has been analyzed. The investigations, made by light microscope show that the pollen of these species is spherical in shape and round in outlines, comparatively big. These morphological characteristics of the pollen of the wild Bulgarian Crocuses define it as a primitive one . The Scanning Electron Microscope investigations, made by Beug , established two types of pollen morphology. The results of our investigation led to the conclusion that the same types are also presented in Bulgarian species: - C.biflorus -type, or syncolpate and C.vernus - type, or inaperturate. Eight of the species belong to the first type and only C. pallasii belongs to the second. The pollen of C. reticulatus is with quite unclear aperture - maybe transition to the inaperturate type.

The protein diversity of 45 genotypes (forty genotypes selected within two gene pools and five varieties) of meadow fescue was examined. Genetic variation was described using ISTA/UPOV methods for crop variety identification. Modifications of acid-PAGE of alcohol-soluble proteins (prolamins), and SDS-PAGE of salt-soluble proteins (globulins) were elaborated for seed analyses of Festuca pratensis Huds. The results of this study indicated that the genotypes of meadow fescue could effectively be differentiated on the basis of polymorphism, detected between protein patterns. SDS-PAGE presented a higher differentiation power and better repeatability; thus could be used as a rapid and reliable method for the identification of F. pratensis genotypes in breeding programmes and the seed industry.

There is a long tradition in the cultivation of pulses in the Balkans and the Iberic Peninsula, mainly used for human consumption. Among the major food legumes common bean is the most important. A large range of landraces are still grown that have adaptation to local climatic conditions and resistance or tolerance to diseases and pests allow high yield stability under a low input farming. The main purpose of this work was to analyze the morphological variability of 15 Portuguese and 15 Bulgarian landraces in different environmental conditions (in Bulgaria and Portugal) in order to generate information that can help identifying the most suitable resources with good adaptability to different environments. The landraces were evaluated for 16 morphological characters. A considerable morphological variation was found among genotypes. The majority of landraces had white seeds colour but some had also cream, purple and white with red colours around the hillum. The predominant seed shape was long but three accessions have round shape. The geographical site of the trials (Elvas, Portugal or Sadovo, Bulgaria) determined the cluster pattern of the majority of accessions. In Portugal, the plants required more days to reach the flowering and maturity phases and had higher biological yield. In both environments, the components that mainly determined yield were the number of pods and the number of seeds per plant. The highest value for these traits were found in one Portuguese accession (No. PH2) and one Bulgarian accession (No. 99E0128), in both experimental conditions. © Journal of Central Europian Agriculture 2013.
