Climate effects on yield components as affected by genotypic responses to variable environmental conditions in upland rice systems at different altitudes por Shrestha, S., Asch, F., Dusserre, J., Ramanantsoanirina, A., Brueck, H.

“…For this, we conducted field trials comprising 10 upland rice genotypes representing a large share of genetic variation, with two sowing dates in two consecutive years in three altitudinal locations creating 12 environments in Madagascar. Crop duration, grain yield and yield components (tillers per hill, panicles per tiller, grains per panicle, sterility, grain weight) were strongly affected by sowing dates, location, year and genotypes. …”
