Data shown are means of 100 seeds/20 plants from five different lots ± sd. SW, mean thousand seed weight in mg; PW15, mean dry shoot mass at 15 DAS in mg/plant; PW28, mean dry shoot mass at 28 DAS in mg/plant; sd, standard deviation. Self, self-pollination; manual, manual pollination of emasculated flowers; self restr. = self-pollination of a restricted number of flowers (five to six) per plant. Sig., Different letters indicate significant differences between the lines (P < 0.001).
