Comprehensive Evaluation of Main Traits of Sugarcane Germplasm Resources with High Sucrose Content

[...]in 42 sugarcane germplasm samples with high sucrose, GT07-1Ü4, GTÖ4-1029, GT041001.[...]collecting excellent high sucrose samples and analyzing their diversity are helpful for improving the evaluation and utilization of these high sucrose sugarcane varieties (strains), and providing references for introduction of sugarcane parents and construction of core germplasm bank. 2 Samples and methods 2.1 Experiment methods One-year plant and ratoon were planted in the field experiment during Januar)1 2014 and December 2015.According to the results of sugarcane yield in Table 2 , 11 new plants had the yield higher than the control group, GT07104 had the highest yield of 137.72 t/ha, which was 49.2% higher than the conlrol group; ihe yield of 28 samples of raloon was 3% -78% higher than the control group ROC22 (73.65 l/ha) , and ihe difference wilh GT07-104 reached extreme significance, and the difference between GT07-110 and GT07-135 reached the significant level.In the sugarcane breeding, the germplasm materials are various, the cost for evaluating the sugarcane juice is high, and it is necessary to carry out the analysis from sugarcane production place to laboratory.[...]in October or early mature period of November, measuring the field Brix can rapidly evaluate and analyze the sucrose content of sugarcane materials.
