Authors: V.M. Abreu, I.C. Silva Neta, E.V.R. Von Pinho, G.M.F. Naves, R.M. Guimar�£es, H.O. Santos and R.G. Von Pinho
Low water availability is one of the factors that limit agricultural crop development, and hence the development of genotypes with increased water stress tolerance is a challenge in plant breeding programs. Heat-resistant proteins have been widely studied, and are reported to participate in various developmental processes and to accumulate in response to .. Read More»

Authors: N.B. Alves, J.M.V. P�¡dua, K.O.G. Dias, R.P. Diniz, M.L. Guedes, G.A. Cardoso and J.C. Souza
The objective of this study was to evaluate the performance of 119 full sib progenies of the fifth cycle of reciprocal recurrent selection (RRS) derived from of Universidade Federal de Lavras maize breeding program. The experiment was carried out in an 11 x 11 triple lattice design at two locations (Lavras, Lambari). The plots consisted of two rows of 3 m.. Read More»

Expression of genes related to tolerance to low temperature for maize seed germination
Authors: I.C. Silva-Neta, E.V. Pinho, A.D. Veiga, R.G. P�¬nho, R.M. Guimar�£es, F. Caixeta, H.O. Santos and T.L. Marques
The aim of this study was to characterize maize lines tolerant to cold temperatures during the germination process. Seeds from lines with different levels of tolerance to low temperatures were used; 3 lines were classified as tolerant and 3 as susceptible to low germination temperatures. A field was set up to multiply seeds from selected lines. After the .. Read More»

Bayesian inference to study genetic control of resistance to gray leaf spot in maize
Authors: M. Balestre, R.G. Von Pinho, A.H. Brito
Gray leaf spot (GLS) is a major maize disease in Brazil that significantly affects grain production. We used Bayesian inference to investigate the nature and magnitude of gene effects related to GLS resistance by evaluation of contrasting lines and segregating populations. The experiment was arranged in a randomized block desi.. Read More»

Combining ability of tropical maize lines for seed quality and agronomic traits
Authors: L.M. Moterle, A.L. Braccini, C.A. Scapim, R.J.B. Pinto, L.S.A. Gon�§alves, A.T. do Amaral J�ºnior and T.R.C. Silva
Studies of genetic effects of early selection of maize based on seed quality traits are rare, especially those that use materials from different heterotic groups. These studies are also useful in tropical environments and for the advancement of sustainable agriculture with cropping during seasons not commonly used for cultivat.. Read More»

Sample sizes to estimate mean values for tassel traits in maize genotypes
Authors: C.A. Wartha, A. Cargnelutti Filho, A.D. L�ºcio, D.N. Follmann,J.A. Kleinpaul and F.M. Sim�µes
Tassel traits are important in maize breeding programs aiming to reduce the size and number of branches and maintain satisfactory pollen production in order to increase grain yield. The objectives of this study were to determine the sample size (number of tassels) required to estimate the mean values for tassel traits in maize.. Read More»

Molecular mapping of quantitative trait loci for drought tolerance in maize plants
Authors: H. Rahman, S. Pekic, V. Lazic-Jancic, S.A. Quarrie, S.M.A. Shah, A. Pervez and M.M. Shah
Drought tolerance is one of the most important but complex traits of crops. We looked for quantitative trait loci (QTLs) that affect drought tolerance in maize. Two maize inbreds and their advanced lines were evaluated for drought-related traits. A genetic linkage map developed using RFLP markers was used to identify QTLs asso.. Read More»

Prospecting of popcorn hybrids for resistance to fall armyworm
Authors: N.C.S. Crubelati-Mulati, C.A. Scapim, F.A. Albuquerque, A.T. Amaral Junior, M. Vivas and M.A. Rodovalho
The fall armyworm, Spodoptera frugiperda, is the pest that causes the greatest economic losses for both common corn and popcorn crops, and the use of resistant plant genotypes is an important tool for integrated pest management. The goal of the present study was to evaluate the damage caused by S. frugiperda on single-cross popcorn hybri.. Read More»

Relationship among physiological quality, heterosis, and amylase gene expression in maize seeds
Authors: G.E. Oliveira, E.V.R. Von Pinho, T. Andrade, J.C. Souza, F. Caixeta and R.A.D.C. Ferreira
In this study, we analyzed heterosis, amylase enzyme gene expression, and the physiological quality of maize seeds with different genotypes and sizes, which were subjected to aging and not subjected to aging. We used seeds from 2 maize lines that differed with regard to physiological quality, the hybrid, and the reciprocal hybrid; they were classified int.. Read More»

Combining ability of S3 progenies for key agronomic traits in popcorn: comparison of testers in top-crosses
Authors: V.J. de Lima, A.T. do Amaral Junior, S.H. Kamphorst, G.F. Pena,J.T. Leite, K.F.M. Schmitt, C. Vittorazzi, J.E. de Almeida Filho and F. Mora
The successful development of hybrid cultivars depends on the reliability of estimated combining ability of the parent lines. The objectives of this study were to assess the combining ability of partially inbred S3 families of popcorn derived from the open-pollinated variety UENF 14, via top-crosses with four testers, and to c..
