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.

“…At this point, the seeds are considered as germinated seedlings. According to Goggi et al (2008), seed quality is described as a seed viability and vigour, which allows normal seedlings to emerge in a various of field conditions. The SC test, the accelerated ageing (AA) test, and the Soak test are some of the procedures used to assess seed quality.…”

The germination characteristics response for some selected maize hybrids and their parental inbred lines were observed and evaluated in an in vitro trial. The aim of the study was to determine the differences within the performance of some hybridization pathways. Single cross (SC), double cross (DC) and three-way cross (TC) hybrids and their parental inbred lines were studied. The results showed that the germination of maize seeds started after the third day and completely germinated on the seventh day after sowing. Hybrids SC (F1), DC (F1), and TC (F1) showed excellent germination performance with a 100% germination rate on the fifth day and produced the highest shoot and root lengths with 7.9 cm, 7.6 cm, and 6.9 cm (shoot length) and 12.9 cm, 13.9 cm and 14.9 cm (root length), respectively. Thus, the results obtained clearly show that the hybrid seeds have higher germination rate (100%), and the seedlings were more vigorous compared to the parents.

“…Se considera semilla de buena calidad cuando ésta presenta pureza varietal y física, alto desempeño fisiológico y libre de patógenos, atributos que determinan la germinación, vigor y longevidad (Bishaw et al, 2007;Goggi et al, 2008;Courbineau, 2012;ISTA, 2015;García-Rodríguez et al, 2018). En México, con excepción de estudios como el de Gutiérrez et al (2006), Fernández et al (2015 y Noriega et al (2019), se ha realizado poca investigación sobre calidad de semilla en trigo.…”

La calidad de la semilla es un concepto agronómico que considera atributos físicos, fisiológicos, genéticos y sanitarios; los cuales permiten un establecimiento adecuado del cultivo para lograr buena productividad óptima. Alrededor de 95% del trigo cultivado por la humanidad es trigo harinero, producto obtenido por los programas de mejoramiento genético alrededor del mundo. El objetivo de este estudio fue evaluar las características de calidad física de 24 variedades de trigo provenientes de la colección del Instituto Nacional de Investigaciones Forestales, Agrícolas y Pecuarias. La semilla de las variedades para el análisis de calidad se incrementó en condiciones de campo durante dos ciclos. El diseño experimental empleado fue bloques completos al azar con cuatro repeticiones. En la evaluación se agruparon las variedades en ocho décadas de acuerdo con el año de liberación y se analizaron los datos de dos formas, por variedades y años y por décadas. Se evaluaron tres variables y los resultados indican que para peso de mil semillas se aumentó hasta en 30% su valor en variedades modernas; mientras que para peso volumétrico fue de 7%, para porcentaje de humedad no se detectó diferencia entre las variedades generadas en las diferentes décadas. Las 24 variedades evaluadas tuvieron un comportamiento aceptable bajo los estándares que la industria semillera demanda. Se concluye que el mejoramiento genético de trigo en México ha influenciado de manera positiva y de forma significativa en el peso de mil semillas.
