ASSESSMENT OF SAINFOIN BREEDING MATERIAL ON PRODUCTIVITY
Abstract
If we choose sainfoin during growing it can increase productivity of the crop. For the purpose we should take the varieties which are well adapted to the local weather-climatic conditions. In the years 2011-2014 we studied hybrid populations of sainfoin, assessed their valuable biologic and economic traits and according to the obtained data we selected those of them which were more adaptive to increasing climate aridity and possessed better productivity and quality. We used individual-family selection of hybrid populations, obtained in a poly-crossing. Then we selected the most valuable varieties due to a complex of economic traits to use them in breeding. We identified and developed new sources of high productivity of green mass and seeds, of high quality of green mass, hay yield. In the competitive variety testing we selected sainfoin varieties, which exceeded the standard variety ‘Zernogradsky 2’ on 8-20% on average with 28,9 t/ha green mass of ‘Sin 47/95’, 27,2 t/ha of ‘Sin 1/97’, 27,5 t/ha of ‘Sin 4/2010’ and 27,9 t/ha of ‘Sin 5/93’. The seed productivity of sainfoin is one of the most essential traits. During the two cycle period seed productivity of the varieties ‘Sin 5/93’, ‘Sin 1/2000’, ‘Sin 6/95’ and ‘Sin 4/2010’ was 0,67 t/ha, 0,68 t/ha and 0,70 t/ha respectively. Bio chemical assessment of the selected varieties according to raw protein content in dry matter showed that the varieties ‘Sin 5/93’ and ‘Sin 4/2010’ possessed the same amount of it as the standard variety; the varieties ‘Sin 1/2000’, ‘Sin 47/9’ and ‘Sin 5/2010’ exceeded the standard one on 0,57%. The varieties ‘Sin 5/93’, ‘Sin 4/2010’ and ‘Sin 1/2000’ produced the greatest yields of hay with 38%,38% and 39% respectively.
