“…In this study, the hybrid DKB 290 PRO3 exhibited the highest values of plant height and ear insertion height (Table 3). Such outcome supports the findings of Freitas et al (2017), who also observed the superiority of this cultivar over the others, as for the same variables.…”

The present work evaluated the segregation of the RR-biotechnology and the agronomic performance of maize hybrids originated from three seed categories: single-cross commercial hybrids, double-cross hybrids, and saved seeds (F2 population). The experiment was set up in the field, within a producing area used for market purposes, in São Miguel do Iguaçu, Paraná, Brazil. The research followed a randomized block design with four repetitions. We investigated the following treatments: saved seeds/F2 population (MG 580 PW, MG 30A37 PW, MG 600 PW, and MG 545 PW), seeds of single-cross commercial hybrids (MG 580 PW, MG 30A37 PW, AS 1777 PRO3, AG 9000 PRO3, and DKB 290 PRO3) and home-bred seeds/double-cross hybrids (DKB 290 PRO3 x MG 30A37 PW, DKB 290 PRO3 x DKB 285 PEO3, DKB 290 PRO3 x DOW 2B587 PW, and DKB 290 PRO3 x MG 600 PW). The study considered agronomical characters, as well as the segregation of the RR-biotechnology. The hybrids MG 580 PW and DKB 290 PRO3 were the most productive ones, yielding 9,244.31 and 9,151.84 kg ha-1, respectively. The groups formed by double-cross and F2-population hybrids had the highest average values of RR-biotechnology segregation (20.5% and 13%, respectively). The group of commercial hybrids proved to be superior to the others in all variables appraised, and they also did not show segregation of the RR-biotechnology. The principal component analysis made it possible to sort the three categories of seeds. In conclusion, despite the high cost, the commercial seeds stood out showing the best cost-benefit for maize crops.

“…The analysis of variance analysis revealed that corn hybrids in the regions of west Bahia and south-west Goias were significant (p <0.01) (Table 1). Corroborating with [4,15,16,17,18]. The mean values among the hybrids were similar with 150.44 and 149.85 sc ha -1 , respectively, for West Baiano and Sudoeste Goiano, respectively (Table 2).…”

The objective of this study was to evaluate the yield of corn hybrids in west Bahia and south-west Goias in the agricultural year of 2017/2018. The study was carried out in the municipalities of Luís Eduardo Magalhães in west Bahia - BA and Mineiros in south-west Goias – GO, Brasil. The experimental design was a randomized complete block design, the treatments being corn hybrids, 12 in west of Bahia and 23 in south-west of Goias. Each experimental unit was composed of 6 lines of 8 m in length spaced every 0.5 m and population of 70.000 ha-1 plants in 4 replications. The applications of pesticides were carried out in the morning, and the control of weeds, insects and diseases were carried out whenever necessary respecting the good practices of integrated pest management. After the harvest the yield was determined, correcting the grain moisture to 14%. Statistical analyzes were carried out at the Rbio and R interface. The analysis of variance analysis revealed that corn hybrids in the regions of west Bahia and south-west Goias were significant. The cultivation of the DKB390, MG711, DKB290 and 30F53 corn hybrids is recommended for west Bahia and the P3707 hybrid that has obtained yields above 170 sc ha-1 in south-west Goias. For both regions it was evidenced that the UPGMA grouping method using the generalized distance of Mahalanobis was efficient.

“…No presente experimento a variedade CA9, com uma média de altura de 257,00 cm e a CA1 com média de 207,83 cm de altura, mesmo sendo variedades crioulas, apresentaram valores semelhantes aos híbridos para essa característica, podendo ser portadores do gene braquítico, o qual confere menor porte às plantas (ENTRINGER et al, 2017). O porte baixo das plantas, e consequentemente das espigas, costumam ser características desejadas, principalmente para produtores agrícolas, por gerar plantas com menor comprimento entre nós, favorecendo o equilíbrio da planta sobre seu centro de gravidade e reduzindo assim possíveis perdas por acamamento ou quebra de plantas, além de facilitar a colheita mecanizada (FREITAS et al, 2017). Entretanto, segundo Silveira et al (2015), as plantas mais altas são mais vantajosas quando empregadas para a produção de silagem de planta inteira, devido a maior produção de matéria verde.…”

O presente trabalho objetivou caracterizar dez variedades locais de milho, cultivadas por produtores rurais do município de Carlinda, (MT) e estimar a diversidade genética por meio de 16 caracteres morfoagronômicos. O delineamento experimental adotado foi o de blocos casualizados com três repetições. Para a caracterização morfoagronômica foram utilizados oito descritores quantitativos e oito qualitativos estabelecidos para Z. mays, de acordo com o Ministério da Agricultura, Pecuária e do Abastecimento (MAPA). A análise de variância revelou diferença significativa entre as médias das variedades para maioria das características avaliadas, sendo que, a altura da espiga, o número de fileiras de grãos e o diâmetro médio de espiga foram as que mais contribuíram para a divergência genética. Os métodos de agrupamento UPGMA e Tocher separaram as variedades em dois grupos uma vez que a maior dissimilaridade foi verificada entre as variedades CA1 e CA7. Foi possível verificar que houve uma significativa discriminação entre as variedades e que essas podem fazer parte de bancos de germoplasma e integrar programas de melhoramento local, como possíveis fontes de alelos favoráveis e adaptados à região Norte de Mato Grosso, não somente atendendo aos interesses dos pequenos produtores da região como também visando a manutenção dos recursos genéticos da espécie.
