The line Jiao 51 was found with high GCA and higher non-additivegeneeffect in the hybrids in which Jiao 51 was a parent. Therefore, Jiao 51 was an elite line.
结果表明，自交系交51具有较高的一般配合力和其配出的组合易出现较强的非加性基因效应。

The results obtained were as follows:The variation of tuber reducing sugar and dry matter contents in cultivated potatoes was wide, and both of them were controlled mainly by geneadditiveeffect.
结果表明，马铃薯栽培种间块茎还原糖及干物质含量的变异很大，并且主要是由基因加性效应引起的。

The additiveeffect of resistant gene was found among the interspecific hybrids.
