Expression of catalase, alcohol dehydrogenase, and malate dehydrogenase in rot grains upon fungicide use on maize hybrids grown at different spacings
Authors: E.R. Kluge, M.C. Mendes, M.V. Faria, H.O. Santos, L.A. Santos and I.E. Sandini
In this study, we evaluated the fungicide effect on the incidence of rot grains and expression of catalase (CAT), alcohol dehydrogenase (ADH), and malate dehydrogenase (MDH) enzymes in commercial maize hybrids grown with conventional and reduced spacing in Guarapuava, PR, Brazil. The experiment was designed in random blocks wi.. Read More»

Descriptive statistics and correlation analysis of agronomic traits in a maize recombinant inbred line population....
Authors: H.M. Zhang, G.Q. Hui, Q. Luo, Y. Sun and X.H. Liu
Maize (Zea mays L.) is one of the most important crops in the world. In this study, 13 agronomic traits of a recombinant inbred line population that was derived from the cross between Mo17 and Huangzao4 were investigated in maize: ear diameter, ear length, ear axis diameter, ear weight, plant height, ear height, days to pollen..

Use of molecular markers in reciprocal recurrent selection of maize increases heterosis effects
Authors: A.P.C.G. Berilli, M.G. Pereira, L.S.A. Gon�§alves, K.S. da Cunha, H.C.C. Ramos, G.A. Souza Filho and A.T. do Amaral J�ºnior
We examined the effect of incorporation of molecular markers on variability between and within populations in order to maximize heterotic effects and longevity of a maize reciprocal recurrent selection program. Molecular variability was quantified by inter-simple sequence repeat (ISSR) markers between and within the maize popu.. Read More»

Genetic parameters in parents and hybrids of circulant diallel in popcorn
Authors: R.M. Rangel1, A.T. Amaral J�ºnior1, C.A. Scapim2, S.P. Freitas J�ºnior1 and M.G. Pereira1
With the aim of estimating genetic parameters and identifying superior popcorn combinations, 10 parents were crossed in a circulant diallel and evaluated together with the 15 resulting hybrids at two locations in two growing seasons for grain yield, number of broken plants, number of partially husked ears and popping expansion. The hybrids were less sensi.. Read More»

Quantitative trait locus analysis for ear height in maize based on a recombinant inbred line population
Authors: Z.Q. Li, H.M. Zhang, X.P. Wu, Y. Sun and X.H. Liu
Maize (Zea mays L.) is among the crops with the greatest worldwide economic importance. Ear height is a very important trait that is considered necessary in maize and is related to morphology, lodging, and yield. To realize its genetic basis, an F9 recombinant inbred line population and a genetic map consisting of 101 simple s.. Read More»

Genetic gains in the UENF-14 popcorn population with recurrent selection
Authors: I.L.J. Freitas, A.T. do Amaral J�ºnior, S.P. Freitas Jr., P.D.S. Cabral, R.M. Ribeiro and L.S.A. Gon�§alves
The popcorn breeding program of Universidade Estadual do Norte Fluminense Darcy Ribeiro aims to provide farmers a cultivar with desirable agronomic traits, particularly with respect to grain yield (GY) and popping expansion (PE). We evaluated full-sib families from the seventh cycle of recurrent selection and estimated the gen.. Read More»

Heterotic groups in tropical maize germplasm by test crosses and simple sequence repeat markers
Authors: C.G. Aguiar, I. Schuster, A.T. Amaral J�ºnior, C.A. Scapim and E.S.N. Vieira
The objectives of the present study were to determine heterotic groups of germplasm lines of tropical maize by test crosses and by simple sequence repeat (SSR) markers and to compare five grouping methods of heterogeneous maize. Sixteen lines of nine populations in the S5 generation were evaluated in test crosses with three testers. The results of four ex.. Read More»

Tissue culture characteristics of maize (Zea mays L.) haploid coleoptile sections
Authors: L. Jiang, G.X. Jing, X.Y. Li, X.Q. Wang, Z. Xing, P.K. Deng and R.G. Zhao
Doubled haploid (DH) technology, which is used for rapidly purifying genetic resources, is a key technology in modern maize breeding. The present study evaluated the tissue culture characteristics of maize haploid coleoptile sections, in order to provide a new way of haploid doubling. With 20 combinations of haploid coleoptile sections, obtained by hybrid.. Read More»
