【摘要】 利用12份玉米自交系按不完全双列杂交配成32个组合,对其主要数量性状的GCA、SCA、TCA和遗传参数进行估算和分析。结果表明:99-78、99-41、99-14、99-6和99-11等自交系的综合性状较优,是组配强优势杂交组合的优良自交系,如99-78×99-41、99-14×99-41;而99-63和99-74等的综合性状较差,需进一步改良方能利用。更多还原

【Abstract】 By using 12 inbred lines of maize, 32 crossing combinations were made according to incomplete diallel cross. Analysising on GCA, SCA, TCA and genetic parameters of quantitanive characters. The results indicated that: The general characters of inbred lines 99-78, 99-41, 99-14, 99-6 and 99-11 were better, they were fine inbred lines in hybrids that were got higher yield on these inbred lines, that were crossed, such as: 99-78×99-41 and 99-14×99-41ect. General charecters of inbred lines 99-63 and 99-74 were worse, only can be utilized after improving.更多还原
