摘要
【目的】时空变化对甜高梁农艺性状的影响。【方法】以TTL-11（CK），7．6—120、Z7—120、Z8—120四个甜高梁品系为材料，分别于2005年在新疆农科院玛纳斯试验站和2005～2006年在海南三亚市新疆农科院南繁试验基地两地进行品比试验，【结果】TTL-11（CK）、Z6—120、Z7—120、Z8—1204个品系的生育期、生物产量、茎秆产量、产糖量、千粒重、单株重、秆重、株高、秆长、茎节数、茎粗在新疆、海南两地的差异达极显著水平和显著水平；生育期、生物产量、茎秆产量、产糖量、单株重、秆重、株高、秆长、茎节数、茎粗在新疆显著高于海南，籽粒产量、千粒重则是海南高于新疆；汁液锤度和籽粒产量在两地的差异不显著；有利于南繁加代。【结论】Z6—120在新疆、海南两地表现高生物产量、中锤度的品种，可作为饲料专用品种应用；Z7—120为高产、高糖品种，其锤度在新疆和海南的均值分别为17．9％、18．6％，产糖量最高，可作为能源专用型品种应用。
[ Objective and Method] The study was used to discuss the varieties comparison experiment separately arranged in two places：Manas Experiment Station and Sanya Experiment Station of Xinjiang Academy of Agricultural Science in 2005 - 2006 , using TTL- 11, Z6 - 120, Z7 - 120 and Z8 - 120 sweet sorghum varieties as experiment materials. [Result]The results indicated that there were significant and extremely significant differences of TTL-11 ,Z6- 120,Z7- 120,Z8- 120 in Xinjiang and Hainan in growing period, the biological yield, stem yield, sugar yield, weight of thousand kernels, every plant weight, plant height, culm length, number of internodes, stem diameter, etc. The sugar brix and the seeds yield had no significant difference in two places which was good for breeding in Hainan. [ Conclusion]The selected two good varieties Z6- 120 and Z7 - 120, Z6 - 120 showed high biological yield and medium brix in Xinjiang and Hainan,which would be used feed variety,Z7- 120 had high biological yield and high brix in Xinjiang and Hainan, it used be energy variety.
