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.
