Comparative petiole anatomy of cassava (Manihot) species

D. Graciano-Ribeiro, Hashimoto-Freitas, D. Y., Nassar, N. M. A., Graciano-Ribeiro, D., Hashimoto-Freitas, D. Y., Nassar, N. M. A., Graciano-Ribeiro, D., Hashimoto-Freitas, D. Y., and Nassar, N. M. A., Comparative petiole anatomy of cassava (Manihot) species, vol. 15, p. -, 2016.

In this study, we describe the petiole anatomy of six wild cassava (Manihot) species, one hybrid, and two cultivars of Manihot esculenta, in order to identify their dominant anatomical patterns and relate them to possible adaptations to abiotic factors in the Cerrado biome. The median parts of several petiole samples were transversally and longitudinally sectioned and stained.

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.

Molecular genetic analysis of heterosis in interspecific hybrids of Argopecten purpuratus x A. irradians irradians

L. P. Hu, Huang, X. T., Sun, Y., Mao, J. X., Wang, S., Wang, C. D., and Bao, Z. M., Molecular genetic analysis of heterosis in interspecific hybrids of Argopecten purpuratus x A. irradians irradians, vol. 14, pp. 10692-10704, 2015.

Argopecten purpuratus and Argopecten irradians irradi­ans hybridization was successfully performed and the hybrid offspring displayed apparent heterosis in growth traits. To better understand the genetic basis of heterosis, the genomic composition and genetic varia­tion of the hybrids were analyzed with amplified fragment length poly­morphism (AFLP) and simple sequence repeat (SSR) markers. Seven of eight universal SSR primers displayed polymorphism in the hybrids and their parental groups, and hybrids inherited both parental geno­types at each locus.
