Abstract

The objective of this work was to evaluate yield of eight cucumber inbred lines and heterosis of hybrids from intercrosses parcial diallel (4 x 4), in non heated green house allowed open pollination by insects. The experimental design was randomized blocks with 27 treatments: 16 experimental hybrids, three commercial hybrids (Safira, AG-221 and Guarani), four S5 lines from population SHS and four S4 lines from population GH, with four replicates and six plants per plot. The following traits were evaluated: total fruit number and fruit weight per plant, commercial fruit number and commercial fruit weight per plant and percentage of commercial fruits. Heterosis and superiority in relation to superior parent were estimated. Experimental hybrids H35 and H43 had the highest yield. Both positive heterosis of hybrids over lines, and general heterosis, in relation to superior parental were obtained. (AU)
