摘要/Abstract

摘要： 采用幼胚培养技术，获得了栽培大麦纤毛鹅观草之间的属间杂种。研究了杂种F1，F2和BC1的形态和细胞学特点。结果表明：杂种形态介于双亲之间，不同生育阶段其主要特征分别倾向双亲之一。在结实率和主要经济性状上F2和BC1较F1有相当大的提高，但生育期进展不大。根尖染色体计数和花粉母细胞减数分裂构型分析表明：F1、F2和BC1

Abstract: Intergeneric hybrid between cultivated barley (Hordeum vulgare L. 2n=14II) and Roegneria ciliaris (Trin) Nevski, (2n=28, SSYY) was successfully obtained by means of embryo culture. The morphology and cytology of the hybrid F1, F2 and BC1 were studied. The results indicated that the hybrid F1 and it
