Chino. 选用新育成及育种中常用的5个甜高粱不育系、5个甜高粱恢复系,按不完全双列杂交法组配25个杂交组合,对株高、生育期,含糖锤度、叶绿素、产量等5个性状用DPS数据统计软件进行了分析。结果表明：不育系303A,综合性状表现突出,一般配合力高,是一个较理想的甜高粱不育系,其次为L0202A较好;恢复系LTR108、LTR114表现好,一般配合力高;综合产量和含糖锤度表现,303A/LTR114、L0202A/LTR108及L0202A/LTR114是比较理想的甜高粱杂交组合。本研究为甜高粱的高糖高产栽培和品种选育提供了可靠的理论依据。

Five A（male sterile） lines and five R（restorer） lines of sweet sorghum were selected to examine their combining ability for major agronomic traits.Twenty-five crossing combinations were made by incomplete diallelic cross method and plant height,growth period,Brix,chlorophyll and yield were analysed with statistical software DPS.The results showed that the sterile lines 303A was an ideal sweet sorghum sterile lines with outstanding comprehensive character and high general combining ability,followed by L0202A.The R lines LTR108 and LTR114 showed good performance and high general combining ability.The combinations of 303A/LTR114,L0202A/LTR108 and L0202A/LTR114 are ideal high yield and Brix contente.Our results provided evidence for selecting the right combinations for high sugars and high yield.
