Genetic effects of in vitro germination and plantlet development in chilli pepper
Authors: P.A. Barroso, M.M. R�ªgo, E.R. R�ªgo and K.T.C. Ferreira
The objective of this study was to estimate the genetic effects on in vitro germination and development of chili peppers. For this, four genotypes (UFPB-132, -134, -137, and -390) were used as parents. They were crossed in a complete diallel scheme. The parents (4) and hybrid (12) seeds were germinated in glass bottles contain.. Read More»

Combining ability for yield and fruit quality in the pepper Capsicum annuum
Authors: N.F.F. do Nascimento, E.R. do R�ªgo, M.F. Nascimento, C.H. Bruckner, F.L. Finger and M.M. do R�ªgo
The objective of this study was to determine the effects of the general and specific combining abilities (GCA and SCA, respectively) of 15 characteristics and to evaluate the most promising crosses and the reciprocal effect between the hybrids of six parents of the Capsicum annuum species. Six parents, belonging to the Horticu.. Read More»

Analysis of genetic traits for drought tolerance in maize
Authors: R.W. Muhammad, A. Qayyum, A. Hamza, M.Q. Ahmad, N.S. Naseer, S. Liaqat, B. Ahmad, W. Malik and E. Noor
Fifty-four genotypes of maize were crossed and evaluated in the field during the crop season in February 2012 under both normal and water stress conditions. To identify the major parameters responsible for variation among genotypes, single linkage cluster analysis and principle component analysis (PCA) were carried out. Thirteen characters were studied. T.. Read More»

Potential of maize single-cross hybrids for extraction of inbred lines using the mean components and mixed models with microsatellite marker information
Authors: M. Balestre, R.G. Von Pinho, J.C. Souza and J.C. Machado
The present study examined the importance of mean (m+a’ and d) components in the performance of single-cross hybrids for the formation of new populations and determined the contribution of the mixed model (best linear unbiased predictor of random effects, BLUP) method associated with molecular markers for the choice of crosses to obtain interpopulat..

Diallel analysis of corn for special use as corn grits: determining the main genetic effects for corn gritting ability
Authors: T.V. Conrado, C.A. Scapim, L.S. Bignotto, R.J.B. Pinto, I.L.J. Freitas, A.T. Amaral Jr. and A.C. Pinheiro
Corn grits are used for various purposes such as flakes, snacks, livestock feed, hominy, extruded products, beer, etc. The grit size proportion varies according to the hybrid, and thus, once the use of the grits is linked to the particle size, determining the genetic effects is essential to develop hybrids for any specific use..

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»
