Abstract: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.
