Rezumat

Our study starts from the general need of conservation in order to ensure proper and valuable utilization of plant genetic resources. Legumes represents a valuable source of food proteins, and their exploitation is expected to grow in relation of a growing world's food need. The breeding and exploitation of new varieties is a decisive factor in improving rural income and overall economic development. We developed prebreeding activities in order (1) to save precious resources that are endangered, by collecting local native populations, old, primitive varieties, (2) to improve national Phaseolus collection and (3) to ensure proper evaluation of plant genetic resources in order to be used in breeding programs. In Romania, the largest and the most representative Leguminosae collection is maintained by the Gene Bank Suceava and representative collection is also held in Vegetable Research and Development Station, Bacau. The study’s focus was on Phaseolus vulgaris, Phaseolus coccineus and Vigna radiata species. The proposed research methodology and techniques were conducted at Vegetable Research and Development Station, Bacau and University of Agricultural Sciences and Veterinary Medicine Iaşi, and were designed as laboratory and field experiments on a diverse biological material, with valuable genetic origin, obtained in collecting missions in Romania and from different germplasm exchanges with different gene banks, accomplished in order to investigate the suitability in diffrent ecological conditions. The accessions were examined for morpho-agronomical traits in conventional and ecological field trials in accordance to passport descriptors. Phenological observations and biometric measurements included data on following characteristics: earliness, resistance or tolerance to pests and diseases, production quality and quantity were accomplished. Characteristics on the occurrence of the first flower and first pod could provide clues on earliness. Productivity was assessed by the number of pods/ plant, number of seeds in pods, weight of 1000 grains (MMB). To determine the attack of pathogens, we used a conventional scale, giving the notes to the degree of attack. The newly acquired knowledge and data will enable better and efficient management of Phaseolus resources. The development of new improved legumes genotypes, suitable to biological and conventional system, can solve problems related to: safe and sufficient food, alternative sources of food for judicious use of resources, decrease the agricultural inputs for conservation of the environment quality. „This work was supported by a grant of the Romanian Ministery of Research and Innovation, CCCDI - UEFISCDI, project number PN-III-P1-1.2-PCCDI-20170850/contract 14 PCCDI /2018, within PNCDI III”.
