Table 2.

Weight of tubers from single‐stem plants of A2 HSc70‐expressing lines. Fresh weight (FW) and dry weight (DW) are measured in grams (g)

Trait measured	Line 33 (g)	Line 48 (g)	Line 56 (g)	WT (g)
FW at 20°C	11.9 ± 4.0a	14.7 ± 4.9b	11.2 ± 3.8a	10.6 ± 2.1a
FW at 28°C	15.3 ± 5.1b	19.7 ± 8.8b	17.6 ± 4.9b	8.8 ± 1.8a
DW at 20°C	1.89 ± 0.63a	2.93 ± 0.98b	1.7 ± 0.57a	1.96 ± 0.30a
DW at 28°C	2.7 ± 0.90b	4.80 ± 1.00c	2.90 ± 0.73b	1.39 ± 0.27a

Data are presented as mean ± standard error (n = 9) and different letters indicate significant differences between lines (Fisher's, P < 0.05).
