Relevance. The effect of heterosis is of great importance in crop breeding. Heterosis is defined as an increase in the value of the trait of F1 hybrids compared to the average value of both parents. In grain sorghum breeding, heterosis is widely used to increase the yield and expand the adaptive abilities of hybrid plants.Methods. The object of research was 13 of the most precocious F1 combinations of grain sorghum and their parent forms. The crossing scheme includes seven maternal (Ros, Zernishko, Slavyanka, Ogonek, Premiere, Mercury, Orlovskoye) and 6 paternal (Ros, Zernishko, Slavyanka, Ogonek, Belochka, Mercury) forms grain sorghum. The parameters of heterosis were calculated using the method of D.S. Omarov.Results. The greatest effect of true heterosis along the length of the panicle was revealed in the combinations: Slavyanka — Ogonyok (15.6%), Premiere — Mercury (15.0%), and the highest value of hypothetical heterosis was found in the crosses Ogonyok — Ros (22.2%), Slavyanka — Ogonyok (20.1%) and Premiere — Mercury (20.3%). Also, a high degree of phenotypic dominance was found in the combinations Slavyanka — Ogonyok (5.1) and Premiere — Mercury (4.4). Evaluation of hybrids and parental forms shows that many of them exceeded their parent in terms of grain yield from one plant, thus showing true heterosis, which varied from 6.1% in the Zernyshko — Ogonyok hybrid to 49.5% in Premiera — Ros. The highest values of hypothetical heterosis appeared in combinations Ogonyok — Ros and Premiera — Ros — 62.8% and 51.7%. In hybrid combinations, the degree of dominance varied from 0.6 to 34.0. Overdomination was noted for the Premiera — Ros combination (34.0) and the Ogonyok — Ros (6,7).

Sweet sorghum has the ability to store sugar in its stem. Many sugar content genes have been discovered and through breeding worldwide. However, some of these genes are unstable. This study aimed to detect and validate QTL for stem oBrix content from sorghum RILs. In two seasons, QTL linked with stem brix content and related traits were examined using 139 F8RILs from a grain and sweet sorghum. A genetic linkage map with 128 SNP markers was created and several QTLs were identified. Phenotypic variation between 6.33 and 14% was identified for a given trait. Over two seasons, four QTLs for stem brix content (qBrix2-1, qBrix4-1, qBrix4-2, and qBrix10-1) and three QTLs for stem diameter (qSD1-1, qSD8-1 and qSD9-1) were detected. The detected QTL could be useful for improving stem brix content in different growing season. Furthermore, it makes a significant contribution to marker-assisted brix selection and sorghum biofuel improvement.

“…It is known that F1 hybrids often exhibit the effect of heterosis for many economic characteristics, including biomass yield, which depends on correctly selected parental pairs and is widely used by breeders [6]. Therefore, the identification of crossing components with high combinational ability (CA) is the main stage in the breeding for heterosis, which also allows determining the inheritance of the studied trait, the participation of genes (additive and non-additive) in its control [7][8].…”

Combinational ability of crossing components and heterosis of F1 hybrids of sugar sorghum by biomass yield

Currently, the most promising direction of breeding is the creation of F1 hybrids of sugar sorghum, based on the identification and selection of parental forms with high combinational ability. The source material and F1 hybrids were grown in the arid conditions of the Saratov Right Bank (Russia): the hydrothermal coefficient during the growing season was 0.68. The evaluation of the combinational ability of crossing components was carried out using the topcross method. As a result of the tests, the L-52/13 line was identified with high GCA effects (15.71), and the highest SCA dispersions were found in the Saratovskoe 90 variety and the L-39/12 line (91.80-189.27). It was found that the type of sterile cytoplasm of iso-nuclear CMS-lines had a significant impact on the manifestation of SCA in terms of biomass yield: higher dispersion indicators were noted in 9E Zheltozernoye 10 (36.66). Genes with an additive effect are involved in the genetic control of this trait in paternal forms, and non-additive genes in maternal forms. In addition, each hybrid combinationwas observed with superdomination: the coefficient of phenotypic dominance varied from 2.01 to 18.91. It is advisable to use the obtained information in the hybridization of sugar sorghum to obtain high-heterosis hybrids.
