Stability and adaptability of grain sorghum hybrids in the off-season

J. E. Almeida Filho, Tardin, F. D., Daher, R. F., Barbé, T. C., Paula, C. M., Cardoso, M. J., and Godinho, V. P. C., Stability and adaptability of grain sorghum hybrids in the off-season, vol. 13, pp. 7626-7635, 2014.

We analyzed productivity data obtained from experiments on grain sorghum conducted in 7 locations of its cultivation in Brazil. A total of 25 hybrids were analyzed, of which 22 were pre-commercial and 3 were cultivars. The Wricke and Purchase et al. methods were highly consistent in identifying individuals with low contributions to genotype x environment interactions. The Lin and Binns method proved to be easily applicable and interpretable but it was not efficient in detecting individuals with specific adaptations.

Selection indices to identify drought-tolerant grain sorghum cultivars

Twenty-five cultivars of grain sorghum [Sorghum bicolor (L.) Moench] were examined under both drought stress and normal conditions in 4 experiments. In each condition, genotypes were evaluated in a factorial experiment using a randomized complete block design with 3 replications.
