Fig. 1. Frequency distributions of leaf rolling, leaf drying, spikelet fertility and single plant yield among 348 genotypes under moderate drought stress.

Fig. 2. Representative pictures of gravitropic response of primary roots of Dro positive genotypes by using agarose-glass box method along with negative check IR64.A, KalingaIII. B, Lalsankari. C, Dular. D, N22. E, Kasalath. F-H, IR64.

Fig. 3. Frequency distribution of mean root angle of the panel population in response to gravitropic effect (A) and primary mean root angle of genotypes having both Dro1 and Dro2 along with negative check IR64 (B).

Supplemental Fig. 1 Representative electrophoregram obtained with ID07_14 showing target band of 174 bp. The numbers represent the genotypes listed in Table 2.

Supplemental Fig 2. Amplicons obtained with RM6089. The Orange arrow indicates the target allele in Dular (170bp) and the blue arrow indicates IR64 allele (165bp). The numbers represent the genotypes listed in Table 2.

Fig. 4. Graph of K value, an ad-hoc statistic related to the rate of change in the log probability of data between successive K values (A), and population structure of 101 germplasm lines based on membership probability fractions of individual genotypes (B) and population structure of 101 germplasm lines sorted based on serial number of the genotypes (C).

Fig. 5. Principal coordinate analysis (A) and unweighted pair group method arithmatic average (UPGMA) algorithm (B) obtained with the molecular markers for Dro1 and Dro2 loci of 101 genotypes. The dot numbers in the figure represent the serial number of the genotypes.
