The study of early maturing corn hybrids of the Siberian branch
The research was carried out at the Siberian Branch of the All-Russian Research Institute of Corn (Omsk) in 2019-2021. The purpose of the study is to conduct a comparative research of new corn hybrids and identify early maturing and high-yielding hybrids for the cultivation of grain and high-energy silos in the conditions of the southern forest-steppe of the Omsk region. The paper analyzes the results of comparative research of new corn hybrids in terms of grain yield, harvesting structure and duration of the interphase period “seed germination - corn cob blossom”. The hybrids that showed a stable high harvest rate with low harvest moisture were identified: statistical processing of the data obtained by the method of variance analysis and using the Duncan’s criteria for grain yield and harvest moisture was carried out. It was found that hybrids with the RDT898/14M tester are generally more unfavorable in relation to the standard, which indicates a high combinational ability of this tester. Hybrid 135. grain and high-energy silo in the conditions of the south of Siberia. The hybrid RDT898/14 × Om30 stands out significantly in terms of grain yield, and in terms of the duration of the period of seed germination - corn cob blossom and the harvesting moisture content of the grain, it is close to the Siberian 135 standard. This hybrid requires an average of 1960-1980 °С for maturation, which indicates its suitability for cultivation for grain and high-energy silage in the conditions of the South of Western Siberia
