摘要
通过对8 个啤酒大麦品种配置的不完全双列杂交分析,针对株高等8 个农艺性状,依据配合力效应对亲本和组合进行了评价,并且对这8 个农艺性状的广义和狭义遗传力进行了估算。结果表明:矮秆早和浙皮1 号是较好的矮秆亲本,91282 和91272 具有分蘖力强、长穗和粒大的特点,甘木二棱和浙皮1 号是较好的多粒亲本;Schooner×浙皮1 号、矮秆早×91272 、91282×甘木二棱是丰产性状较好的组合;主穗长和株高的广义和狭义遗传力比其它性状较高。
This paper analyses a diallel cross disposed by eight malting barley cultivars.Aimed at eight agronomic traits,the height of plant,parents and combinations are evaluated according to the effect of combining ability.Furthermore,the broad and narrow sense heritabilities of the eight agronomic traits are estimated.The results show:Aiganzao and Zhepi No.1 are better dwarf parents.91 282 and 91 272 have the character of stronger tilling ability,longer spike and larger grain,Ganmuerleng and Zhepi No.1 are better multi grained parents;Schooner×Zhepi No.1,Aiganzao×91 272,91 282×Ganmuerleng are the combinations of high yields.The broad sense and narrow sense heritability of the length of main spike and plant height are bigger than any other traits.\;
