Significant positive correlationswere found between grain yield, panicle traits and the No.of peduncle vascular bundles. So, it is very important tostudy the inheritance of peduncle vascular bundle, whichis a quantitative trait.展开更多

Comparing with parentalrice, LF rice revealed an advantage on its vegetative growing by increasing the yieldsof leave blade, leave sheath and stem for 27.77, 30.19 and 37.96% respectively. And thecellulose content of LF rice straw was decreased remarkably for 23.9%, the hemicellulose,lignin and biogenic silicon contents were increased contrarily for 11.94, 8.79 and 5.60%respectively. Moreover, the crude protein content was increased by 20.71% for LF rice andwith an improvement on its solubility for 63.49% concomitantly. The results indicatedthat the low-fiber mutation rice exhibited its potential as a fodder-rice variety or asdual-purpose rice to improve fiber degradability of straw.展开更多
