B.  aGenetic progress in seed yield of physic nut (Jatropha curcas L.).h[electronic resource]  c2015  aThe objective of this study was to quantify the genetic progress of seed yield using mass selection in a physic nut population at production age, evaluated in the Amazonic tropical climate. Genetic variability for seed yield exists among J. curcas genotypes, denoting the possibility of genetic progress through plant selection. There was also a tendency for the genotypes to maintain their genetic superiority over the time.  aGenetic gain  aGenetic parameters  aOilseed  aSelection1 aRAMALHO, A. R.1 aLAVIOLA, B.
