| Abstract: | The analysis on the yield components of medium indica variety 898 had been done. The results indicated that number of effective panicles was the most important factor to grain yield;the second was number of seed per panicle. The suitable structure of yield (9.0t/hm 2) was as fellow: 2.85±0.15 million effective panicles per hm 2, 160±10 spikelets per panicle, setting rate of 86±2%, and 1000-grain weight of 29.5g. And its high yield cultural techniques were present. |
