Rezumat

Climate change is impacting all aspects of our day-to-day existence and more profoundly the crop production system, which is very critical for the food security of any nation. It is now well recognised that crop production is very sensitive to climate change with different effects according to the region. An increase in temperature, an uneven distribution of rainfall during the growing season of plants, due to frequent droughts, leads to a decrease in its potential productivity. In this regard, the task of creating and introducing high-yielding varieties, capable of realizing the potential of genetically incorporated productivity, with a high quality of seeds in conditions other than optimal, is placed in the foreground. The solution of this problem depends largely on the gene pool of the starting material. The improvement of food crops in the world is mainly based on mutation. Experimental mutagenesis methods are successfully used to obtain valuable starting material. One of these methods is gamma-rayinduced mutagenesis. In our studies performed at Institute of Genetics, Physiology and Plant Protection of the Republic of Moldova, induced mutagenesis was used-a treatment with gamma rays, followed by individual selection of the desired valuable forms. The investigated material presents lines obtained in M7 generation. For comparative analysis, was two cultivars (Zodiac and Alina) of soybean, approved in R. Moldova were used as standard samples. Dry seeds were irradiated with gamma rays, with doses of 100, 150, 200 and 250 Gy and sown on the experimental field according to generally accepted methods for this culture. The studies were conducted in three different years of 2016‒2018. From the progeny M5 - M7, mutants lines were selected, which by total yield differ significantly from plants of the control samples: precocity (108‒133 days), plant height (74.5 to 102.5 cm.), the number of nodes on the main stem (9‒21), height of pod insertion, number of pods (63‒132), the number of seeds in the pods (124‒328), yield per plant, shape, color and weight of 1000 ‒ seed. The obtained results based on the calculation of yield showed that some lines, depending on the conditions of the year, exceeded the values of standard samples, while others were inferior to them. Lines mutants obtained have precious traits and will be used for breeding of soybean in R. Moldova. So from the above, it is obvious that the gamma radiation is useful in the induction of genetic variability, that present a large spectrum of mutations and a high frequency of their manifestation.
