经济遗传值在甘蔗选育种应用研究系列(Ⅵ)甘蔗第九轮国家区域试验品种评价

Breeding Application Research Series of Economic Genetic Values in Sugarcane(Ⅵ)Evaluation of the Varieties for the Ninth National Regional Test of Sugarcane

以第九轮国家区试的10个甘蔗品种为材料,通过2年新植、1年宿根试验,对蔗茎产量、甘蔗蔗糖分、甘蔗纤维分3个重要经济性状进行了经济遗传值(Economic genetic values,EGV)分析,并据品种对花叶病和黑穗病的抗性等级对EGV加以校正。结果表明:产量表现较好的品种有‘德蔗03-83’、‘福农1110’;甘蔗含糖量表现较好的有‘福农1110’、‘福农0335’、‘德蔗03-83’及‘柳城05-136’;参试品种中,‘福农1110’、‘柳城05-136’、‘闽糖01-77’和‘德蔗03-83’经济遗传值表现为正,其中‘福农1110’和‘柳城05-136’表现最为突出,分别为165.86元和145.24元。该评价结果与利用农艺性状评价结果基本一致,简单高效,在后续甘蔗区域试验及品种评价中可加以利用。

In this study,10 sugarcane varieties in the ninth national regional test were used as materials.The economic genetic value(EGV)of three important economic traits(cane yield,sugar content and fiber content)were analyzed through 2-year plant and 1-year ratoon crops.The performance of resistance to Mosaic disease and Smut were used to correct EGV.The results showed that Dezhe03-83 and Funong1110 had better yield performance.Funong1110,Funong0335,Dezhe03-83 and Liucheng05-136 had better sugar content performance.Among the tested varieties,Funong1110,Liucheng05-136,Mintang01-77 and Dezhe03-83 showed increase of EGV.Among which,Funong1110 and Liucheng05-136 had better performance of EGV with an increase of 165.86 Yuan and 145.24 Yuan,respectively.The results of the EGV evaluation were basically consistent with agronomic traits evaluation,simply and efficiently.The results indicated that EGV could be used in the subsequent national regional test and variety evaluation for sugarcane.
