12个HoCP系列甘蔗种质资源初步鉴定和评价

Preliminary Identification and Evaluation of 12 Strains of HoCP Series in Sugarcane Germplasm Resources

为了解甘蔗(Saccharum spp.)亲本特性,以ROC22为对照,对12个重要Ho CP系列亲本种质进行了初步鉴定与评价。结果表明,Ho CP系列品系具有出苗率高、分蘖性好、有效茎数多、早熟高糖等特性。Ho CP01-564含糖量最高,Ho CP00-1142产量最高,Ho CP02-610发芽率和有效茎数最高,Ho CP07-613蔗糖分最高。聚类分析表明,12个Ho CP系列品系(种)可分为4类。因此,根据这些品系(种)特性可以合理配制杂交组合。

In order to understand the parental characteristics of Saccharum spp.,twelve important parents of HoCP series were preliminarily identified and evaluated with ROC22 as a control.The results showed that HoCP series clones were characterized by high emergence rate,good tiller,large effective stem number,early maturing and high sucrose content.Among them,HoCP01-564 showed the highest sugar yield,HoCP00-1142 had the highest yield,HoCP02-610 had the highest emergence rate and effective stem number,and HoCP07-613 had the highest sucrose content.The cluster analysis showed that all of the clones could be divided into 4 groups.Therefore,these characteristics would be used to make crosses in the future.
