| Popis: | In plants with bisexual flowers, the development of hybrids and F1 seed production is only possible by using cytoplasmatic male sterility. The discovery of such sterility and the maintainers has made it possible to utilize the phenomenon of heterosis to improve yields and yield components in forage sorghum. It has been shown that the best way to develop forage sorghum hybrids is to cross grain sorghum as the female parent and Sudan grass as the male. The objective of this study was to develop a forage sorghum hybrid for the production of green matter to be used either fresh or for silage. The sorghum hybrid developed in these efforts (Siloking) is intended for multiple cutting, as the basal nodes produce buds and regrowth takes place. The performance of the new hybrid with respect to yield and quality was compared to that of the forage sorghum cultivar NS Džin. In a two-year study conducted under different growing conditions in four locations, Siloking produced an average green matter yield of 86.29 t ha-1 (two cuts), a dry matter yield of 25.34 t ha-1, and a crude protein content of 11.85 %. Siloking outperformed NS Džin in terms of yield and quality. . |
