Heterosis effect in sorghum sudangrass hybrids at brooming stage
Tsvetan Kikindonov, Kalin Slanev, Stanimir Enchev, Georgi Kikindonov
Abstract: Two-year study was conducted for the production of green and dry mass from three swaths in brooming phase. F1 sorghum × sudangrass hybrids of two selected sudangrass pollinators with eight MS lines of grain sorghum of the breeding program of Agricultural Institute – Shumen were tested. The pollinator SVE is an elite origin – a typical Sudan grass, while SZE is a stabilized population after hybridization with sweet sorghum. In brooming stage the majority of tested sorghum x sudangrass hybrids have higher productivity of green and dry mass than standard varieties. No matter the unfavorable conditions during the vegetation in the period of study the highest heterosis effect in the productivity have been realized by the hybrids SC × SVE and S13 × SZE.
