Figure 2.

Genotype-by-trait biplot analysis of 66 genotypes for first two principal components. LTR1-low temperature regime of 25°C for 3 days; LTR2-low temperature regime of 15°C for 7 days; LTR3-low temperature regime of 8°C for 7 days; LTR4-low temperature regime of 4°C for 7 days; LTR5-low temperature regime of 4°C for 14 days; LTR6-low temperature regime of 4°C for 21 days. The numbers in the figure represent the serial number of the genotypes enlisted in Table 1.
