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 Horticultural Germplasm Bank of Centro de Ciências Agrárias of Universidade Federal da Paraíba, were crossed in complete diallel manner. The 30 hybrids generated and the parents were then analyzed in a completely randomized design with three replicates.

Diallel analysis of corn for special use as corn grits: determining the main genetic effects for corn gritting ability

T. V. Conrado, Scapim, C. A., Bignotto, L. S., Pinto, R. J. B., Freitas, I. L. J., Amaral, Jr., A. T., and Pinheiro, A. C., Diallel analysis of corn for special use as corn grits: determining the main genetic effects for corn gritting ability, vol. 13, pp. 6548-6556, 2014.

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. For this purpose a complete diallel series of crosses, involving eight parents, was performed near Maringá, PR, Brazil.
