Performance of grain sorghum hybrids under drought stress using GGE biplot analyses

The objective of this study was to estimate the adaptability and stability of grain sorghum hybrids grown under post-flowering water stress and non-stress conditions. The trials were carried out in Nova Porteirinha-MG during the season of 2014 and 2015, and in Teresina-PI in the 2014 season. Twenty-nine-grain sorghum hybrids were evaluated, in a randomized complete .. Read More»

The aim of this study was to identify sorghum hybrids that have both high yield and phenotypic stability in Brazilian environments. Seven trials were conducted between February and March 2011. The experimental design was a randomized complete block with 25 treatments and three replicates. The treatments consisted of 20 simple pre-commercial hybrids and five witnesse.. Read More»

Selection of sorghum hybrids grown under aluminum saturation

    C.B. Menezes, G.A. Carvalho Junior, L.A. Silva, K.C. Bernardino, J.V. Magalhães, C.T. Guimarães, L.J.M. Guimarães and R.E. Schaffert

The purpose of this study was to evaluate 165 hybrids derived from lines previously selected for aluminum (Al) tolerance. Nine check cultivars were used, eight commercial hybrids and one experimental hybrid. Hybrids were evaluated at three levels of Al saturation (0, 20 and 40% on average). The differences between the environments were significant. Environment with .. Read More»

Multi-trait BLUP model indicates sorghum hybrids with genetic potential for agronomic and nutritional traits

    J.E. Almeida Filho, F.D. Tardin, J.F.R. Guimarães, M.D.V. Resende, F.F. Silva, M.L. Simeone, C.B. Menezes and V.A.V. Queiroz

The breeding of sorghum, Sorghum bicolor (L.) Moench, aimed at improving its nutritional quality, is of great interest, since it can be used as a highly nutritive alternative food source and can possibly be cultivated in regions with low rainfall. The objective of the present study was to evaluate the potential and genetic diversity of grain-sorghum hybrids for traits of agronomic and nutrition.. Read More»

Evaluation of grain yield in sorghum hybrids under water stress

    C.B. Menezes, D.C. Saldanha, C.V. Santos, L.C. Andrade, M.P. Mingote Júlio, A.F. Portugal and F.D. Tardin

Sorghum grain yield can be significantly affected by climatic changes, especially drought and high temperature. The purpose of this study was to evaluate hybrids of grain sorghum grown under normal irrigation conditions or water stress in order to select those likely to be more tolerant of drought. Forty-nine hybrids were grown in a randomized block design experimen.. Read More»
