THE HIGHLIGHTING OF SOME WHEAT GENOTYPES AS A SOURCE OF GERMOPLASM FOR THE IMPROVEMENT OF THE MAIN ELEMENTS OF PRODUCTIVITY

Abstract

Abstract. The aim of this study was to highlight wheat genotypes with a high number of grains/spike, with a good weight of grains/spike, and with a thousand kernel weight > 50 g, which can be used in wheat breeding programs. In 2022, at ARDS Turda, from 45 winter wheat genotypes (a small part of the collection that contains 1181 wheat genotypes), variant 23 was identified as a source of germplasm for improving productivity elements. It had an average of 78.4 grains/spike, a good weight of grains/spike (> 4.5g) and a high value of the thousand kernel weight (58.81g), close to that of the Arieşan variety, which is consecrated for this character. Five wheat genotypes with more than 80 grains/spike and eight genotypes with a thousand kernel weight greater than 55 grams were also identified.
