“…Corn (Zea mays L.) is cultivated throughout Brazil, and is prominent owing to its diverse uses, among which is the cultivation of special corns, such as baby corn. Such cultivation refers to female inflorescences of any type of corn that are harvested after the emission of the stigma-style (Targanski & Tsutsumi, 2017) during the initial development stage, before pollination.…”

The cultivation of special corns, such as baby corn, has had a positive influence on the economy of the country. Despite its importance, there is still a need for studies aimed at increasing production and planting areas of the crop. Phytosanitary studies are of particular interest, as the cultivation of such crops is susceptible to a series of pathogens, such as Bipolaris maydis, Exserohilum turcicum, and Puccinia polysora. The use of resistant cultivars is the most effective way to prevent the occurrence of these diseases. Thus, the present study aimed to identify popcorn lines that have the potential for baby corn production and are resistant to the main leaf diseases that affect the crop. The experiment was conducted in randomized blocks with four replications of 30 lines in each area, during two planting seasons. The area was located at the Federal Institute of Espírito Santo (IFES) Campus of Alegre, situated in Rive district, Espírito Santo State, Brazil. Using the obtained data, the area under the disease progress curve was obtained. Subsequently, analysis of the joint variance of the data was conducted, and when a significant effect was found, a grouping of means test was conducted. The Mahalanobis distance for each pair of lines was also calculated, and the genetic distance matrix was used to construct a dendrogram using the UPGMA method. Considering the averages obtained for the three diseases (Southern corn leaf blight, Northern corn leaf blight, and Southern rust), lines L61, L63, L65, L683, L684, L685, L691, L694, and L695 were identified as possible donors of resistance alleles for multiple diseases. Multivariate analysis efficiently grouped the lines L61, L63, L684, L685, and L691, which are described as most resistant in the univariate analysis.

“…Grains are an important commodity on the world stage, and the Brazilian corn seed market is focused on grain-producing cultivars with a reduced number of cultivars on the market for the production of sweet corn, in which the double hybrid AG 1051 ® can be highlighted (NASCIMENTO et al 2017). Similarly, the sweet corn and popcorn cultivars have been used for the production of baby corn (TARGANSKI & TSUTSUMI 2017). COSTA et al (2020b) have tested, in Piranhas (State of Alagoas, Brazil), different maize genotypes (creole variety, free pollination, and double hybrids) and all produced baby corn with commercial standards.…”

O milho apresenta múltiplas funções, podendo ser utilizado no consumo humano, alimentação animal ou em processos industriais. A produção de grãos tornou o Brasil uma referência mundial. Porém, apesar da relevância do milho verde, principalmente para agricultores familiares, são poucos os cultivares disponíveis. Do mesmo modo, para o minimilho, em que são utilizados milho doce ou pipoca para sua obtenção. Na região semiárida, as produções vegetal e animal são limitadas pelo déficit hídrico na época seca. Portanto, com a produção de milho verde e minimilho é possível obter renda com a comercialização das espigas e produzir volumoso com a colheita da planta inteira. O objetivo dessa pesquisa foi avaliar o desempenho agronômico de cinco cultivares para produção de milho verde e minimilho e produção de forragem no Agreste Meridional, região semiárida de Pernambuco. Foram realizados dois experimentos no delineamento em blocos casualizados, com cinco tratamentos (AG 1051, Alagoano, Branquinha, São Luiz e PV2 Viçosense) e quatro blocos. No primeiro experimento avaliou-se o desempenho dos cultivares para produção de milho verde e forragem, em que os cultivares AG 1051 e Branquinha tiveram, respectivamente, maiores produtividades de espigas comerciais (21,9 e 20,3 Mg ha-1) e de forragem (10,7 e 10,9 Mg MS ha-1). No segundo experimento, avaliou-se o desempenho dos cultivares para a produção de minimilho e forragem, em que os cultivares AG 1051 e PV2 Viçosense obtiveram a maior produtividade de espiguetas comerciais (3,1 e 2,9 Mg ha-1, respetivamente); Branquinha, maior produtividade de forragem (8,9 Mg MS ha-1). Portanto, esses cultivares reúnem características desejáveis, podendo ser utilizados em sistemas intensivos ou extensivos de produção.
