摘要
Abstract
For the purpose of making clear the characteristics of rice varieties in cold region, randomized to design method was used to statistics analyze yields of main 32 new rice varieties of Heilongjiang province in 2010. The results showed that grain number per spike and seed setting rate had significant negative correlation,and significantly correlation with the yieId. The varieties with more panicles per hole but less grain number per panicle, the yield was increasing; The varieties with tall plant height were with more grains per panicle;More grains per panicle but lower seed setting percentage, but the yield was increasing; So it should reduce panicles per hole（tillering number）,increase the grains per panicle,that was middle titlering ability and partial large panicle variety was advantageous to increase yield. The order of contribution ratio to yield increasing from big to small was leaf width, flag leaf length, 1 000-grain weight,panicles per hole, plant height and seed setting percentage.关键词
