Abstract: RESUMO O objetivo deste trabalho foi estimar a capacidade de combinação de 47 linhagens de milho desenvolvidas pela Universidade Estadual de Maringá, no sentido de identificar as linhagens mais promissoras para utilização em programas de melhoramento voltados para safrinha. Para isso, as linhagens foram cruzadas em topcrosses com dois híbridos comerciais adaptados à safrinha (P30K75 e AG9010), utilizados como testadores de base genética estreita. Os topcrosses foram avaliados em experimentos delineados em bloc… Show more

“…Therefore, for plant height, the selection of plants with lower values is interesting. A shorter cycle length facilitates an optimized exploitation of the areas by different crops in rotation and a greater chance of phytosanitary stability and frost resistance, which is essential in second season crops (Bolson et al, 2016).…”

“…Rosa et al (2020) also reported the good performance of tester 70.H26.1 in exploring the genetic variability among forage maize progenies. In this context, the tester that provides the highest estimates of genetic variance among topcross hybrids is the most appropriate, allowing the expression of the genetic variability of the progenies and highlighting the ones with greatest genetic merit (Guimarães et al, 2012;Bolson, Scapim, Clovis, Amaral Junior, & Freitas, 2016;Miotto et al, 2016;Figueiredo et al, 2018).…”

“…With the aim of obtaining new early commercial hybrids adapted to the conditions of the second crop season or for the breeding populations (Miranda et al, 2003;Teixeira et al, 2015;Bolson et al, 2016), crossing lines of groups I and II is suggested, provided they belong to distinct heterotic groups (Paterniani, 2001). In order to predict some of these crosses, we considered the longest distances between the lines in the Mahalanobis matrix (Table 6).…”
