- ... Introgression of diverse germplasm into the current soybean [ (L.) Merr.J genetic base may increase genetic variability and lead to greater gains from selection. The objective of this research was to evaluate the genetic diversity and agronomic performance of experimental lines derived from plant introductions (Pis) maintained in the USDA Soybean Germplasm Collection. These Pis are known to be gen ...

- ... Morphological characters were assessed for 112 Tunisian apricot accessions using 42 qualitative and quantitative traits according to the UPOV descriptor. The results showed a distinction among all the accessions, and each morphological variable tested was polymorphic except mucron and rootstock. This characterization revealed that Tunisian apricot germplasm complied with many of the listed UPOV de ...

- ... The modern cultivated potato (L.) was first recorded in Europe in the Canary Islands in 1567, but its origin has long been in dispute. Two competing hypotheses have proposed an “Andean” area (somewhere from the Andean uplands from Venezuela to northern Argentina) or a lowland south-central “Chilean” area, but the Andean origin hypothesis is today generally accepted. The identity of extant Canary I ...
