摘要:
为促进矮秆、早熟、优质谷子选育，以嫩选15和大金苗杂交组合F2-群体为研究材料，对F2-群体1 104个单株的株高、穗长、茎长、穗粗、节数、穗重、穗粒重等主要农艺性状进行分析。结果表明：该组合F2-群体株高、穗长、节数、茎长、穗粗等主要农艺性状的偏度和峰度几乎都小于1，呈正态分布，穗重、穗粒重的偏度和峰度均明显大于1，呈现偏离正态分布；各农艺性状之间均显著正相关；其中株高分离特别明显，F2-群体中株高低于120 cm的个体达到了46.29%，为矮秆育种增添了丰富的新型矮秆遗传基础资源。
Abstract:
In order to promote the breeding of dwarf,early maturity and high quality millet,this research took the 1 104 F2- individuals of Nenxuan 15 and Dajinmiao as the materials.Seven major agronomic traits such as plant height,spike length,stem length,spike weight,grain weight per spike,diameter of spike,spike type,and node number were analyzed.The results showed that the bias and peak of the main agronomic traits such as plant height,spike length,node number,stem length,diameter of spike of the F2- population were almost all less than 1,and they were normally distributed.The bias and peak of the spike weight and grain weight per spike were all significantly greater than 1,departure from the normal distribution; There was significant positive correlation among the agronomic traits.Among them,plant height separation was particularly obvious.Individuals with plant height below 120 cm in the F2- generation reached 46.29%,which added rich new genetic resources for dwarf stalks breeding.
