The same leaf area can be reached with different cell area, cell number, and EF. Five genotypes with the same final leaf 6 area were extracted among the 200 genotypes studied. Four issued from the mutant collection, and the last one is a RIL from the Ler × An-1 population. These genotypes reached a similar leaf area (A) but with different cellular components (EF [B], mean epidermal cell area [C], and epidermal cell number [D]).
