2.2 | Morphological analysis
Morphological analysis was performed on R. stricta , R.
turczaninovii and putative hybrids. Agronomic traits were observed
including plant height, tiller number, floret number, length of flag
leaves, width of flag leaves, length of spikes, etc. Each trait was
measured 10 times and the average was calculated. The pubescence of
leaf, basal leaf
sheath
and stem node were recorded by direct observation.
