Genotype x environment interactions for a diverse set of sweetpotato clones evaluation across drought prone environment of Mozambique. por Andrade, M.I., Ricardo, J., Grüneberg, W.J.

“…Ratios of variance components due to genotypes, genotype x year, genotype x treatment, genotype x year x treatment, and the plot error were 1: 2.90:0.52:1.27: 3.98 for storage root yield and 1:0.45:0.13:0.29: 1.45 for upper biomass yield – corresponding heritabilities were 37.6 and 74.5, respectively. The stability of harvest index was significantly correlated with the PCA1 and PCA2 values obtained from AMMII analysis with storage root yields. …”

Effects of genotype, seed P concentration and seed priming on seedling vigor of rice por Pame, A.R., Kreye, C., Johnson, D., Heuer, S., Becker, M.

“…While the presence of the Pup1 QTL in IR74 increased shoot biomass and total root length, these effects could be further enhanced by water priming. Combining genetic and seed management approaches may contribute to improved rice establishment in P deficient soils but its effectiveness depends on genotype and seed attributes.…”

Bean Program: The VEF(IBN)-EP-IBYAN scheme por International Center for Tropical Agriculture

“…One golden rule followed was that no breeder would send early generation materials to countries outside his work areas to avoid overwhelming national programs with huge amounts of genetic material still being developed. To benefit national programs with the materials produced by all breeders, the Program established that they should deliver their best F4 to be evaluated for one year in the VEF by the entire bean team (pathologist, entomologist, virologist, plant physiologist, and agronomist). …”
