| 摘 要： | 以松辽06-6和吉玉粳两个粳稻品种为试验材料, 2006-2008年连续三年在其适应种植区域进行异地多点正常栽培条件下,研究其穗大小、穗粒数、千粒重等遗传特性对产量的影响。经过三年试验结果表明:品种的产量与穗数、粒数、结实率,均达到显著水平,而与穗长和穗粒数未达到显著水平。初步明确了粳稻品种的丰产性好坏主要取决于株型、分蘖力、成穗率、穗粒数和结实率,为育种家选育既高产又稳产的粳稻品种,提供了具有参考价值的数据。

| Abstract: | Taking the two japonica rice varieties Songliao 06-6 and Jiyu japonica as test materials, genetic characteristics such as ear size, number of grains, grain weight were studied. The materials were planted in their off-site multi-point normal cultivation conditions for three consecutive years 2006-2008. Results showed that: the yield of the varieties and ear number, grain number, seed setting rate, have reached significant levels, while ear length and kernel number per spike does not meet the significant level. It is initially defined that the high-yield of japonica rice varieties mainly due to good plant type, the ideal, tillering, paniclerate, grains per spike and seed setting rate, which provide reference value data for breeding high yield and stable yield japonica varieties. |
