Seed sizes and hundred-seed-weights of T3 homozygous lines. Morphology of seeds harvested from OE6 (a), null-line 6 (b), OE14 (c), null-line 14 (d), OE20 (e), null-line 20 (f) and WT (g) plants. All three OE lines produced larger seed size than null-lines and WT plants. (h) The seeds from all three overexpressor lines had higher-hundred-seed weights. Values are means ± SD (n = 4). Different lower case letters indicate significantly different means (p < 0.05).
