This work was carried out to identify the population with the most significant potential to obtain this line type. For this, nine commercial hybrids’ F1 and F2 generations were evaluated in four environments, involving two years and two seasons each year. The traits evaluated were the number of days to female flowering (NDF) and physiological maturity (NDPM), dry matter accumulation rate (RATE), and grain yield (YLD). For each trait, the contribution of the loci in homozygosity (m+a) and heterozygosis (d) was estimated. NDF, NDPM, and RATE predominated an additive effect with a higher m+a estimate. Regarding YLD, the estimate of d was much higher than m+a, indicating the greater importance of dominance. Hybrid 5 is the most promising for obtaining the segregating population because it associates a high m+a, and d estimate that, although it was not among the highest, represented 56.03% of the average. For this hybrid, considering the YLD, the mean of the lines in F∞ will be the highest and associated with sufficient variability in the population to enable successful selection.","PeriodicalId":34859,"journal":{"name":"Revista Brasileira de Milho e Sorgo","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48987855","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Currently, this technique stands out as a promising biotechnological tool for the improvement of different crops, overcoming the limitations of conventional breeding methods and accelerating the development of plants’ agronomic characteristics. The basic principle of genome editing via CRISPR is to cause a double-stranded DNA break at a predetermined location by a sgRNA (single guide RNA) and through internal repair mechanisms cause mutations and, consequently, genetic variability. In prokaryotic organisms, it is an immune system that naturally protects against viral infection and has been modified to create different applications in higher organisms in the field of medicine and agriculture. In agriculture, it has been used in a large number of mono and dicotyledonous plants, including those of great commercial value such as soybean, cotton and maize. In maize, this technique has been used as a biotechnological tool for increasing production, quality, nutritional value, tolerance to biotic and abiotic stresses. CRISPR-Cas9 technology has enormous potential to contribute to increased food production with great benefit to the environment. This review explores the bases for the use of CRISPR/Cas9 technology to generate genetic variability and its use in the development of maize cultivars with better agronomic characteristics.","PeriodicalId":34859,"journal":{"name":"Revista Brasileira de Milho e Sorgo","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-05-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47417389","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The present study aims to evaluate the efficacy of post-emergence herbicides applied to maize while inferring the sustainability of the treatments employing an ecological approach. The experiment was installed in a randomized block design with four replications. The treatments consisted of the application of atrazine at the dose of 1500 g ha-1; atrazine + mesotrione at 1500 + 72 g ha-1; atrazine + tembotrione at 1500 + 100.8 g ha-1; atrazine + nicosulfuron at 1500 + 22.5 g ha-1; atrazine + glyphosate at 1500 g ha-1 + 792.5 g ha-1, in addition to weeded and infested control treatments. The herbicides were applied at the 4 leaf stage of maize. The phytotoxicity and control efficacy was assessed 7, 14, 21, and 28 days after applying treatments (DAT). In addition, a phytosociological survey of all plots was carried out in the last assessment. Herbicides did not cause phytotoxicity symptoms to the crop. However, associations of atrazine with glyphosate and atrazine with tembotrione promoted the greater effectiveness of weed control. Despite being classified as one of the treatments with better effectiveness, the association between glyphosate and atrazine, caused a more significant reduction in the diversity of the plant community, and alternative weed management practices should be applied to maize cropping fields to avoid weed selection.","PeriodicalId":34859,"journal":{"name":"Revista Brasileira de Milho e Sorgo","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-05-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48021750","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Over the last twenty years, many studies presented genomic selection (GS) as a tool contributing to this goal. Currently, many research papers have shown encouraging results in the application of GS. However, there are few examples of long-term, successful applications of GS in plant breeding programs. Furthermore, for breeders and researchers considering the application of GS, there are a series of important considerations on how to adapt a breeding program to maximize the benefit of GS, aiming to reduce the costs and maximize the genetic gains. Under this perspective, we present a review with a general view about applied GS in maize breeding, future perspectives of this technique, and an applied study case of a breeding program using GS. We attempt to provide a brief review of the literature with recent developments, as well as a discussion involving the number of markers required to deploy GS, the different statistical approaches to create GS models, the different ways to define training populations, and the incorporation of non-additive effects and genotype by environment interaction. We end with general recommendations and conclusions about some critical points about adopting GS in maize breeding.","PeriodicalId":34859,"journal":{"name":"Revista Brasileira de Milho e Sorgo","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-04-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44269614","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Thus, the objective of this review was to contribute information concerning the process of popcorn breeding in tropical regions, germplasm availability, popcorn breeding plans, the main characteristics related to popcorn quality and yield, and advances and perspectives in the process of popcorn improvement. The main focus of breeding programs is to obtain hybrids from inbred lines with high popping expansion (40 mL g-1) and yield (4.000 kg ha-1). The genetic improvement performed in Brazil has presented significant advances, mainly due to work developed in public institutions with the development of new hybrids that present more significant popping expansion and yield. However, the number of cultivars is still low, and most of them are controlled by private companies. Therefore, intrapopulation methods are recommended to develop open-pollinated varieties with high popping expansion, and this trait can be used as an early predictor of promising inbred lines to obtain superior hybrids for grain quality. Furthermore, popping expansion can be quickly recovered in backcrosses involving the cross of common maize with an inbred popcorn line.","PeriodicalId":34859,"journal":{"name":"Revista Brasileira de Milho e Sorgo","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-04-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45766074","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
