今年8月8日至12日在哈尔滨召开了玉米花粉单倍体育种学术讨论会。出席会议的代表来自14个省市31单位共52人。美国波斯顿学院生物系丁玉澄教授参加了这次讨论会并作了学术报告。 我国玉米花药培养的研究工作进展很快。自1077年春获得花粉纯系以来,据不完全统计已有14个单位从25个材料中(包括品种和杂交种)获得了自交系。近年来,根据几个单位在10个花粉自交系进行的120个测交组合中,许多组合超过了当地推广的杂交种。 会上,认真地交流了花粉植株自交系的稳定性和
August 8 this year to 12 held in Harbin, corn pollen haploid breeding seminars. The delegates attending the meeting came from 31 provinces and 14 provinces and 52 units in total. Professor Ding Yucheng from the Department of Biology, Boston University took part in the symposium and gave an academic report. The research on maize anther culture in China has progressed rapidly. Since the spring of 1077, pure pollen lines have been obtained, and in incomplete statistics 14 inbreds have been obtained from 25 materials (including varieties and hybrids). In recent years, many combinations outnumber locally-promoted hybrids, according to several of the 120 quiz combinations made by 10 units in 10 pollen inbred lines. At the meeting, the stability of pollen plant inbred lines was carefully exchanged
