New Genotypes of Leaf Mustard (Brassica juncea), Bred and Acclimatized at Vegetable Research and Development Station Buzau

Since 1996, Brassica juncea has been studied in the Breeding Laboratory of Vegetable Research and Development Station Buzau. The aim of this study was to obtain genotypes with distinct phenotypic expressivity, suitable to be grown in protected spaces and field, adapted to the pedoclimatic conditions of our country. The genetic potential of the germplasm collection was evaluated and the seven obtained families were measured biometrically and phenologically. G1 has been registered since 2017 at The State Institute for Testing and Registration of Varieties Bucharest for approval under the temporary name ‘Aroma’

A valuable germplasm collection has been made for this species and the new genotypes will be proposed for approval

Research on the acclimatization and breeding of Sideritis hyssopifolia L. in Romania

Sideritis hyssopifolia L., perennial plant of the genus Sideritis, is also known as hyssop-leaved mountain ironwort. In its area of origin in northwestern Europe, it is valued as an aromatic and medicinal plant and used in the prevention and treatment of digestive ailments. It has been studied at Plant Genetic Resources Bank Buzău since 2019, being the subject of intensive acclimatization and improvement works with the purpose of obtaining new creations with distinct genotypic and biochemical characteristics. The genetic material used was from the centers of origin: Spain, Portugal, Madeira and Canary Islands, and the breeding methods were repeated individual selection followed by negative mass selection. In order to prevent the biological contamination of genotypes with foreign pollen, insulators with textile material were used. Cultivar G5, superior in terms of acclimation and genetic stability, also exhibited distinct phenotypic expressivity. At the same time, specific culture technology was developed with the aim of promoting it among farmers

Evaluation of the Agricultural and Quality Potential of the New Aubergine Genotype Obtained at the Buzău Plant Genetic Resources Bank

Taking into account the increasing demands of farmers and consumers in terms of diversification of the assortment of aubergines marketed in Romanian markets, the Buzau Plant Genetic Resources Bank aims to contribute to its improvement by breeding and promoting new varieties, acclimatized to the growing conditions specific to our country. From the germplasm plots, the stable genotypes that passed the general and specific combining capacity test were subjected to hybridization work resulting in a large number of hybrids, of which the L R10V22 x L O58V22 combination was of interest for the breeding program. As a result of the hybrid combinations, genotype A RO19VER22 was extracted, showing the following distinct and uniform fruit characteristics: fruit weight -590.35 g, fruit length -21.5 cm, obovate fruit shape, light green fruit color with slight striations, and greenish flesh, with an early ripening period. In the present research work, we have succeeded in stabilizing a new eggplant variety, with distinct phenotypic expressiveness, to be registered and approved under the aegis of the Buzau Plant Genetic Resources Bank

Sideritis syriaca – A New Species Introduced into Culture in Romania

Sideritis syriaca is an endemic plant in the mountains of Crete, well-known from the antiquity (Karousou R. et al., 1992). Also named Malotira, it has been used as an anti-inflammatory, antimicrobial, antioxidant and analgesic agent in folk medicine (Goulas V. et al. 2014). In Romania, the Domnesc variety was created in 2019 as a result of breeding and acclimatization to S scardica. Acclimatization, identification of suitable areas for cultivation in Romania and breeding to obtain genotypes with distinct phenotypic expressiveness that meet the international norms of the DUS test are the study’s purpose. The genetic resources are from the germplasm collection of P.G.R.B. and endemic resources acquired from the area of origin and the breeding methods used are repeated individual selection followed by negative mass selection. Type E was selected from the 5 varieties obtained, based on its valuable phenotypic characteristics and good response to environmental conditions; during the three years of study, the plants were monitored, biometric measurements were performed, the culture technology was established; the observations showed an optimal evolution and development of the plants: biomass was 286 g in the first year and 1495 g in the third year. The establishment scheme of the culture was 70 cm between rows and 40 cm between plants/row. Breeding and acclimatization of the S. syriaca species to the climatic conditions of our country were achieved, conditions for the approval of a new variety were created, culture technology was developed

Perspectives on the Extension and Diversification of Basil (Ocimum basilicum L.) Assortment by Exploiting Genetic Resources Conserved at The Plant Genetic Resources Bank of Buzău

The present study aims to evaluate the diversification of the current indigenous assortment of the genus Ocimum by obtaining new distinct genotypes with superior quality, following classical intraspecific hybridization and determination of their chemical composition. The germplasm collection contains 63 genotypes of which 27 are genetic stable. Among the stable genotypes, 4 genitors were studied as breeding material. The breeding procedures used were classical hybridization, negative mass selection and segregation. Laboratory analyses were also carried out in terms of chemical composition description. In the present research work, as a result of intraspecific hybridization, 4 new genotypes were obtained to enrich the local assortment of aromatic and medicinal plants of the genus Ocimum in Romania. The new morphotypes obtained have distinct characteristics and superior qualities

Evaluation of the Main Qualitative and Quantitative Characters in the New Genotype of Salsola Soda Studied at the Buzău Plant Genetic Resources Bank

The present study aims to evaluate a new genotype of Salsola soda, a halophyte plant conserved at Plant Genetic Resources Bank Buzau. Soil salinity is becoming the key factor constraining agricultural production, which is why salt-tolerant species are increasingly being considered and will be of great economic importance. Salsola soda is a plant with multiple uses: food, biodesalinant, companion plant in intercrops. Within the group of halophyte plants conserved in the Bank's germplasm collection, the species Salsola soda has been studied with particular emphasis, carrying out phenological observations, biometric determinations and laboratory analyses according to UPOV and IGPRI descriptors. Following the observations, the genotype L3 was genetically stabilized with the following characteristics: plant height of 134 cm average; plant diameter of 109 cm average, green mass of 2078 g average. The genotype studied meets the DUS test, can be cultivated throughout our country, especially on arid and high salinity soils, and can be used in various human food preparations

Expressivity and Variability of the Cherry Tomatoes Main Characters from Core Collection of Plant Genetic Resources Bank Buzău

The present study aims to phenotypically characterize cherry tomato varieties from core-collection to obtain a new morphotype with distinct phenotypic expressiveness and qualitative characters. Breeding procedures were carried out both in protected and open field for all genotypes under study and the breeding methods used were classical breeding, segregation, and selection.  Following the breeding process, from the segregations obtained, a variety was selected in the F2 generation, genotype L 312 A, which proved to be phenotypically distinct. This genotype is part of the assortment of medium cherry tricolour tomatoes with high firmness, ovoid fruit weighing about 30 g on average, two seed lobes and a length/diameter ratio of 1-1.2. A new tricolour cherry tomato variety was genetically stabilized. It has distinct phenotypic expressiveness and superior quality traits. Prospects aim to approve and patent the variety
