  The main aim of this study is to explore the connections between the unique settlement structure circumstances of Hajdúböszörmény and the social problams related to the gypsy minority. After the change of regime, the gypsy population increased especially quickly in some parts of the city, which is in connection with the settlement network position and the internal division of the settlement. The significant segregation of the gypsy
  minority appeared as a new phenomenon in the city, whose reason was the increasing migration of gypsies from Northeastern Hungary and the relatively low price of the abandoned real estates located in the outskirts and external settlement parts of the city. Even the gypsy population living in the city for a long time separates itself from the immigrant groups that live in run down houses and practicle have no connection with the job market of the city. It is the typical rural segregation process known only in small village regions (e.g. Southern Baranya, Cserehát) that now goes
  on in the outskirts of Hajdúböszörmény.

  In addition to the processing of the available special literature, this study aims to provide an accurate view of the segregation processes in Hajdúböszörmény, as well as their effect on the real estate market by interviewing roma people living in Hajdúböszörmény and by getting to know the opinions of the affected professionals and decisionmakers working at the local authorities.

  In order to analyze the social status of local gipsies – both inside the community and among themselves – we conducted an empirical research of 300 participants, in which we took the distinctive spatioand sociostructural features of Hajdúböszörmény into consideration. Furthermore, a second research was also carried out in which we questioned 25 prominent persons. Participants were selected in a way that the study may give a realistic picture of each of the segregated areas of the town (focusing on social, educational and realty issues), thus besides questioning professionals dealing with the concern of gipsies on a daily basis, we decided to involve representatives of the local government as well. The reports concerning the realty status of the segregated areas were supplemented with further material provided by the local government.

  The effectiveness of selection for improved drought tolerance and consumption quality in the progeny of crosses between pea cultivars with semi-leafless (afila) and normal leaves and different origins, respectively, were investigated. After single crosses, parent cultivars and F1, F2 and F3 generations were grown under non-irrigated conditions in the same trials. We created a colour scale from 1 to 9 to measure statistically the shade of seed colour. The tolerance of genotypes against high temperature was measured by the number of pods per plant. The 3:1 segregation
  observed in the F2 generation of crosses between semi-leafless and conventional cultivars indicated that the semi-leafless character is determined by a recessive gene. In contrast, the ratios of conventional (Af) and semi-leafless (af) genotypes were 7:1 and 9:1 ratio in the progenies of crosses of Af × af. The genetic progress was effective for improving the seed quality in F3 generation from crosses Af x af where we found that multiple
  dominant alleles controlled the orange colour of cotyledons and its high heritability (h2 A=0,63). Selection is more effective in producing the genotypes with high yield and normal leaves if the crosses were made between the western European cultivars such as semi-leafless Profi and Delta used as maternal cultivars and conventional Auralia cultivars. In this case, there were decreases in the consumption quality, such as seed size and shade of colour. The selection based on the seed weight of single plants for increasing drought tolerance seemed to be more effective in F4
  strains with normal leaves originated from Czechoslovakian maternal cultivar Y228; however, the genetic progress in the improvement of seed size and colour quality was slow. 

• The settlement structure-related characteristics and social processes of Hajdúböszörmény after the millennium

  The spatial structural position of Hajdúböszörmény (ease of access) and its economic and social endowments which are more favourable than those of its surroundings make the town more desirable as a target of migration. These endowments are rather advantageous on their own, but the specific settlement structure of the town results in the fact that concentrated, unmanageable and majorly segregated social crisis points have developed in some easily circumscribable parts of the settlement which could lead to a social explosion.
