Effects of Seed Quality and Hybrid Type on Maize Germination and Yield in Hungary

Abstract

After wheat and rice, maize is one of the most significant cereal crops worldwide. However, high-quality seed materials are prerequisites for stable yields, and low-quality maize seeds significantly contribute to low yields and deteriorate over time. Therefore, the present investigation aims to investigate the effects of seed quality and hybrid types on maize germination by emphasizing seed viability and vigor and their impact on maize crops’ overall performance and productivity. The study was separately conducted in the laboratory and on a field experiment plot under the Department of Crop Production, Hungarian University of Agriculture and Life Sciences, in spring 2022. Nine parental lines, six hybrids, and a controlled hybrid were tested in this study. The studies were laid out using a complete randomization design (CRD) and a randomized complete block design (RCBD) in the laboratory and in the field. The results of the study showed that there was a statistically significant difference between genotypes and number of days and their interaction in seed vigor. The parental lines showed better performance in terms of germination percentage and radicle elongation, whereas single-cross hybrids (SC) produced better plumule length. The radicle and plumule length also expanded significantly as incubation days increased. In field evaluations, as expected, hybrid lines produced better performance than parental lines, and SC hybrids were more prevalent than the other hybrids. In addition, the number of rows per ear, number of kernels per ear, 1000-kernel weight, and ear weight directly affected the final grain yield. However, further research is needed on new approaches that can assist researchers in advancing their work by considering biotic and abiotic factors to address seed-quality issues and enhance yield production.
