Mesocotyl and coleoptile length for 57 accessions of RDRS (a), Comparison of mesocotyl and coleoptile length in 4 rice variety groups (b) Japonica (Ja), Tropical Japonica (TJa), Indica-I (In-I), and Indica-II (In-II); Seeds were sown at 5 cm soil depth and incubated at alternate temperatures of 30 °C and 26 °C (14 h/10 h). At 14 days after sowing, the seedling were excavated and length were measured. b Means with different letters in the same row indicate significant differences according to the Duncan multiple range test (P < 0.001). Bars represent mean of length with SE
