Correlations between traits in soybean (Glycine max L.) naturally infected with Asian rust (Phakopsora pachyrhizi)

B. Rodrigues, Serafim, F., Nogueira, A. P. O., Hamawaki, O. T., de Sousa, L. B., and Hamawaki, R. L., Correlations between traits in soybean (Glycine max L.) naturally infected with Asian rust (Phakopsora pachyrhizi), vol. 14, pp. 17718-17729, 2015.

Soybean (Glycine max L.)-breeding programs aim to develop cultivars with high grain yields and high tolerance to Asian soybean rust (Phakopsora pachyrhizi). Considering that the traits targeted for breeding are mainly quantitative in nature, knowledge of associations between traits allows the breeder to formulate indirect selection strategies. In this study, we investigated phenotypic, genotypic, and environmental correlations between the agronomic traits of soybean plants naturally infected with P.

Heterosis for the improvement of yield in mungbean [Vigna radiata (L.) Wilczek]

P. A. Tantasawat, Khajudparn, P., Prajongjai, T., and Poolsawat, O., Heterosis for the improvement of yield in mungbean [Vigna radiata (L.) Wilczek], vol. 14, pp. 10444-10451, 2015.

Heterotic effects of mungbean hybrids from 25 crosses between parents differing in 9 agronomic and physiological traits were evaluated for various selected traits and seed yield. Significant heteroses were observed in most selected traits, except for the number of seeds per plant. When the heterosis of seed yield was evaluated in these hybrids, significant heterosis was found in 9 crosses, which were selected based on the number of pods per plant, number of clusters per plant, pod length, number of seeds per pod, total dry matter, and root length density.
