High segregation distortion in maize B73 x teosinte crosses
Authors: G. Wang, Q.Q. He, Z.K. Xu and R.T. Song
Two genetic linkage maps of cultivated maize inbred lines and teosinte species were constructed. One population comprised 81 F2 individuals derived from a cross between maize inbred line B73 and Zea mays ssp parviglumis, while the second consisted of 63 backcross individuals from a cross of maize inbred line B73 with Z. mays s..

Bulk segregant analysis (BSA) for improving cold stress resistance in maize using SSR markers
Authors: M.Q.U. Farooqi, K.J. Sa, T.K. Hong and J.K. Lee
In this study, eight inbred maize lines with high or low tolerance to cold temperature were investigated using bulk segregant analysis (BSA). Genetic diversity and genetic relationships were investigated using 100 simple sequence repeat (SSR) markers linked to cold tolerance in maize. A total of 319 alleles were identified. Am.. Read More»

Genomic variability of Pantoea ananatis in maize white spot lesions assessed by AFLP markers
Authors: A.M. Miller, J.E.F. Figueiredo, C.L. Chaves, E.A. Ruas, M.I. Balbi-Pe�±a, N.B. Colauto and L.D. Paccola-Meirelles
Measures to control maize white spot (MWS) caused by Pantoea ananatis are preferentially based on resistant cultivars. A lack of knowledge on the genetic variability of pathogens could interfere with the development and utilization of controlling strategies in this pathosystem. The main goals of this study were to investigate .. Read More»

Evaluation on the germplasm of maize (Zea mays L.) landraces from southwest China
Authors: F.B. Chen, Q.L. Yao, H.F. Liu and P. Fang
Because of their local adaptation and economic factors that limit the adoption of commercial hybrids, farmer-saved maize landraces are still grown over a considerable area concentrated in southwest China. To evaluate the potential of using maize landraces, the germplasm characteristics of 96 landraces from southwest China were.. Read More»

Genetic analysis of water-deficit response traits in maize
Authors: M. Ahmad, M. Saleem, M. Ahsan and A. Ahmad
A set of sixty inbred lines of maize (Zea mays L.) were screened in the greenhouse at the seedling stage under both normal and water-deficit conditions. Six water deficit-tolerant inbred lines were selected based on root to shoot ratios. These selected lines were crossed in a diallel pattern. The parental, F1, and reciprocal c.. Read More»

Genetic analysis of agronomic traits associated with plant architecture by QTL mapping in maize
Authors: Z.P. Zheng and X.H. Liu
Maize (Zea mays L.) is one of the most important cereal crops worldwide, and increasing the grain yield and biomass has been among the most important goals of maize production. The plant architecture can determine the grain yield and biomass to some extent; however, the genetic basis of the link between the plant architecture and grain yield/biomass is un.. Read More»

Change in heritability estimates due to half-sib family selection in the maize variety Pahari
Authors: M. Noor, D. Shahwar, H. Rahman, H. Ullah, F. Ali, M. Iqbal, I.A. Shah and I. Ullah
This research was carried out at the Agriculture Research Farm, Khyber Pakhtunkhwa Agricultural University, Peshawar, and the Cereal Crops Research Institute, Pirsabak, Nowshera, during 2009 and 2010. Half-sib families (HS) derived from the maize variety Pahari in spring crop seasons 2009 and 2010 were developed at the Cereal Crops Research Institute. All.. Read More»

Genetic analysis of maize kernel thickness by quantitative trait locus identification
Authors: S.S. Wen, G.Q. Wen, C.M. Liao and X.H. Liu
Kernel thickness is one of the most important traits in kernel structure, and is related to yield. To ascertain its genetic information more clearly, an immortal recombinant inbred line segregation population was used to map the quantitative trait loci (QTLs) for kernel thickness. As a result, two QTLs were identified on chromosome 9; both of them had neg.. Read More»

Comparative quantitative trait locus mapping of maize flowering-related traits in an F2:3 and recombinant inbred line population
Authors: Y.H. Liu, Q. Yi, X.B. Hou, X.G. Zhang, J.J. Zhang, H.M. Liu,Y.F. Hu and Y.B. Huang
Flowering-related traits in maize are affected by complex factors and are important for the improvement of cropping systems in the maize zone. Quantitative trait loci (QTLs) detected using different materials and methods usually vary. In the present study, 266 maize (Zea mays) F2:3 families and 301 recombinant inbred lines (RI.. Read More»
