Heterosis for ether extract production and its components in seed of Cucurbita argyrosperma
Twenty-one genotypes (six parental lines and 15 direct crosses) of butternut squash (Curcurbita argyrosperma subsp. sororia) were evaluated at the Experimental Center of the Universidad Nacional de Colombia in Candelaria (Valle del Cauca, Colombia) during the second semesters of 2012 (2012B) and the...

Heterotic effects (average, variety, and specific) were determined for ether extract production per plant (EEPP) and the following components: percentage ether extract (EE) in seed, seed weight per fruit (SWF), 100-seed weight (100- SW), and number of fruits per plant (NFP).
