Molecular Characterization and Differential Interaction of Xanthomonas axonopodis pv. phaseoli and Xanthomonas fuscans subsp. fuscans with Common Beans (Phaseolus vulgaris)
Authors: De Paiva BAR, Wendland A , Borba TC , Ara�ºjo LG
The common bacterial blight, caused by Xanthomonas axonopodis pv. phaseoli (Xap) and X. fuscans subsp. fuscans (Xff), is one of the most important dry bean diseases of bacterial etiology. The present work aimed to study the genetic structure among and within populations, and also identify the pathogenic variability of Xap and .. Read More»

Diallel crosses for resistance to Macrophomina phaseolina and Thanatephorus cucumeris on cowpea
Authors: L.R.L. Lima, K.J. Damasceno-Silva, M.A. Noronha, D.A. Schurt and M.M. Rocha
This study aimed at identifying and selecting through partial diallel analysis, segregating populations of cowpea resistant to Macrophomina phaseolina and Thanatephorus cucumeris, based on the evaluation of general (GCA) and specific combining ability (SCA), involved in the genetic control of resistance. For this reason, 19 gr.. Read More»

Authors: J.S. Santos, A.T. Amaral J�ºnior, M. Vivas, G.S. Mafra, G.F. Pena,F.H.L. Silva and A.G. Guimar�£es
The present study was conducted to investigate the genetic control and to estimate the general and specific combining abilities of popcorn for agronomic attributes and attributes related to resistance to northern leaf blight (NLB). The 56 hybrids (F1 and reciprocals), together with the eight parent lines and six controls, were.. Read More»

Genetic control of number of flowers and pod set in common bean
Authors: E.S. Martins, R.A. Pinto J�ºnior, A.F.B. Abreu and M.A.P. Ramalho
This article aimed to study the genetic control of some flowers and pod set of common bean and to verify if its estimate varies with environmental conditions and gene pool. A complete diallel was used among six lines, but no reciprocal ones. The treatments were evaluated in three harvests/generations - F2, F3, and F4 - in 2015.. Read More»

Selection of maize inbred lines and gene expression for resistance to ear rot
Authors: G.S. Pereira, R.G.V. Pinho, E.V.R.V. Pinho, L.P.M. Pires, L.A.Y. Bernardo Junior, J.L.A. Pereira and M.P. Melo
In recent years, there has been a large incidence of fungi causing “ear rot” in maize in Brazil, the main fungus being Fusarium verticillioides. The most efficient and competitive alternative for control of this disease consists of using maize hybrids resistant to this pathogen. Thus, the aims of this study were to.. Read More»

Genetic divergence among corn hybrids and combining ability for agronomic and bromatological traits of silage
Authors: E. Gralak, M.V. Faria, A.S.T. Figueiredo, D.A. Rizzardi, M. Neumann, M.C. Mendes, C.A. Scapim and S. Galbeiro
We assessed the impact of genetic divergence and the ability to combine corn hybrids used for the production of silage on the agronomic and bromatological traits of silage quality. We evaluated 18 corn hybrids used as genitors in a circulant diallel scheme in which each genitor hybrid participated in 9 hybrid combinations, and.. Read More»

Relationships between four measures of genetic distance and breeding behavior in spring wheat
Authors: G. Benin, G. Matei, A. Costa de Oliveira, G.O. Silva, T.R. Hagemann, C. Lemes da Silva, E.S. Pagliosa and E. Beche
We estimated the genetic distances among 10 spring wheat genotypes based on pedigree data, morphological traits and AFLP markers, used individually and combined with morphological traits, to find the best predictors of general- and specific-combining abilities among parental genotypes. Ten wheat parents were crossed in a diallel form, disregarding recipro.. Read More»

Genetic distances between popcorn populations based on molecular markers and correlations with heterosis estimates made by diallel analysis of hybrids
Authors: R.E.F. Munhoz1, A.J. Prioli1, A.T. Amaral J�ºnior2, C.A. Scapim1 and G.A. Simon1
Diallel analysis was used to obtain information on combining ability, heterosis, estimates of genetic distances by random amplified polymorphic DNA (RAPD) and on their correlations with heterosis, for the popcorn varieties RS 20, UNB2, CMS 43, CMS 42, Zélia, UEM J1, UEM M2, Beija-Flor, and Viçosa, which were crossed to obtain all possib..

Diallel cross analysis of plesiomorphic traits in Triticum aestivum L. genotypes
Authors: M. Shehzad, S.B. Hussain, M.K. Qureshi, M. Akbar, M. Javed1, H.M. Imran and S.A. Manzoor
We conducted a 5 x 5 complete diallel cross experiment in bread wheat (Triticum aestivum) with the genotypes 6309, Chkwal-50, Dhrabi, Bhkhar-02, and FS-08. Our objective was to evaluate the type of gene action and the general and specific combining abilities required for various morphological traits in wheat. The results of analysis of variance revealed h.. Read More»

Partial diallel crosses for predicting yield of semiexotic maize populations
Authors: C.M. Silva, J.B. Miranda Filho, U.C. Mendes and E.F. Reis
In Brazil, the total production of maize has increased continuously due to the advances in technology but also to the new frontiers for the maize crop, including the expansion of the second crop (safrinha; usually maize after soybean). Therefore, the exploitation of new sources of germplasm seems to be imperative to attend the.. Read More»
