Assessment of groundnut under combined heat and drought stress por Hamidou, F., Halilou, O., Vadez, Vincent

“…Correlation analysis between pod weight and traits measured during plant growth showed that the partition rate, that is, the proportion of dry matter partitioned into pods, was contributing in heat and drought tolerance and could be a reliable selection criterion for groundnut breeding programme. Groundnut sensitivity to high-temperature stress was in part related to the sensitivity of reproduction.…”

QTL analyses for tolerance to abiotic stresses in a common bean (Phaseolus vulgaris L.) population por Díaz, Lucy Milena, Ricaurte, Jaumer, Tovar, Eduardo, Cajiao V., César Hernando, Terán Santofimio, Henry, Grajales Bedoya, Miguel Angel, Polanía, Jose, Rao, Idupulapati M., Beebe, Stephen E., Raatz, Bodo

“…Common bean productivity is reduced by several abiotic stress factors like drought and low soil fertility, leading to yield losses particularly in low input smallholder farming systems in the tropics. To understand the genetics of stress tolerance, and to improve adaptation of common bean to adverse environments, the BAT 881 x G21212 population of 95 recombinant inbred lines (RILs) was evaluated under different abiotic stress conditions in 15 trials across four locations in Colombia, representing two higher altitude (Darién, Popayán) and two lower altitude (Palmira, Quilichao) locations. …”
