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»

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..

Genetic control of agronomically important traits of pepper fruits analyzed by Hayman�s partial diallel cross scheme
Authors: A.R. Schuelter, G.M. Pereira, A.T. Amaral J�ºnior, V.W.D. Casali, C.A. Scapim, W.S. Barros and F.L. Finger
Pepper species of the genus Capsicum have been cultivated over centuries, producing both pungent and sweet fruit; the pungency is caused by alkaloids called capsaicinoids. Among the five cultivated species, Capsicum chinense is one of the most popular, being native to the Amazon basin. This species is characterized by a wide variety of fruit sizes, shapes an..

Genetic improvement of plant architecture in the common bean
Authors: V.M.P. Silva, J.A.N. Menezes J�ºnior, P.C.S. Carneiro2, J.E.S. Carneiro and C.D. Cruz
Knowledge of genetic control of plant architecture in the common bean can help breeders define the most adequate breeding strategy to optimize gains. We examined genetic control of plant architecture in the common bean by means of partial diallel crosses. Fourteen bean lines were crossed under a partial diallel scheme, in which group 1 was composed of 8 e.. Read More»

Genotype x environment interaction and its implication in identification of common bean populations with high calcium content
Authors: S.B. Fernandes, A.F.B. Abreu and M.A.P. Ramalho
The common bean is a food with high mineral content. Of the various types of beans cultivated in Brazil, carioca type beans are the most consumed. The aim of this study was to identify promising common bean populations with an emphasis toward the selection of carioca type bean lines with high calcium content. We also aimed to .. Read More»

Diallel analysis of production traits among domestic, exotic and mutant germplasms of Lycopersicon
Authors: Guillermo Pratta, Liliana A. Picardi, Roxana Zorzoli
The effects of wild germplasm on tomato fruit shelf life have not yet been completely evaluated. Three different genotypes of Lycopersicon esculentum (a cultivated variety, a homozygote for nor and a homozygote for rin), LA1385 of L. esculentum var. cerasiforme, LA722 of L. pimpinellifolium, and 10 diallel hybrids were assayed..
