【摘要】 采用NCⅡ设计,比较新育成旅系辽635和其他3个骨干旅系的配合力情况,对16个杂交组合进行农艺性状和产量配合力分析。结果表明,4个改良旅系小区产量GCA效应值为辽635>丹340选>丹598>铁0255。辽635在增加后代的穗长、百粒重和容重方面有明显的正效应,辽635所组配的全部组合均比对照丹玉39增产。更多还原

【Abstract】 Combining ability between new maize inbred line Liao635 and the other 3 backbone Lüda red cob lines was compared by NCⅡ mating design.Sixteen crosses were evaluated in agronomic traits and combining ability of yield in Shenyang.The results showed that GCA yield effective value: Liao635 > Dan340x > Dan598 > Tie0255.It was significant positive effect in increasing ear length,hundred seed weight and bulk density of the hybrid progeny of Liao635,the yield of all crosses between Liao635 and 4 typical test inbred lines was higher than that of CK.更多还原
