摘  要:
对黄冈市农业科学院2011年的22个晚籼稻新组合(不包括对照金优207))的产量、株高、生育期、结实率和稻米品质的鉴定结果进行了比较分析。分析结果显示,增产的组合占55%,减产组合占45%,且产量与株高、生育期成正相关;结实率与产量及亲本没有明显的相关性;生育期与亲本的不育系没有明显的关系,与恢复系有关;米质的优质率达77%,并与亲本有一定的关系。

摘  要:
The yield, plant height, growth period, the seed-setting percentage and rice quality appraisal of 22 new late indica rice(not including controls Jinyou207) were analyzed by Huanggang academy of agricultural science in 2011. The results showed that the combination of yield increase accounted for 55%. The combination of yield decrease accounted for 45%. The yield and plant height, growth period were positivly correlated. Seed-setting, yield and its parent had no significant correlation.Growth period and sterile lines had no obvious relationship, but were related with restorer lines. The rate of good rice quality was 77%, having a certain relationship with its parents.
