Germplasm
Description The time taken for the leaf to reach a leaf rolling score of 5. The averages
from 5 different plants were used for QTL analyses. For the assay, topmost fully
expanded leaves of five plants were removed near the base and placed in a
chamber (28C, RH 60%, 19.2MJper square meter). Leaf rolling due to dehydration
was characterized on a score of 1 (unrolled) to 5 (completely rolled). The flag
leaves at 70 days after transplanting were used for analyses. Phenotypic effect
contributed by Kasalath allele. Chromosomal locations of putative QTLs were
determined by single-factor analysis (one-way ANOVA) with the general linear
model procedure of QGENE. A probability level of 0.01 was used as the threshold
for detecting significant differences in the mean values of the two genotypic
classes, homozygous for Nipponbare and Kasalath alleles. Two-way ANOVA for
epistatic interaction were also done with QGENE at this threshold. The trait is
not related to either of the abaxial or adaxial stomatal frequencies.
