【摘要】 以杂交满江红榕萍1号(细绿满江红×小叶满江红)为父本,以小叶满江红为母本进行满江红的回交试验,获得大量绿苗和少量白化苗。经同工酶谱鉴定比较、形态观察、生理生化分析确定为杂种后代。并经过室内外抗逆性筛选和品质分析,从该杂交组合后代中筛选出1株性状优良的回交苗,定名为回交萍3号(MH3-1)。本文介绍了回交萍3号在农牧业生产上的应用效果,并分析了其在未来有机农业生产中的应用前景。更多还原

【Abstract】 A back-crossing trial on Azolla that using hybrid Azolla strain Rongping 1 (A. filicuioides ×A. microphylla) as male parent, A. microphylla as female parent was conducted, large amount of green seedlings and some of albino seedlings were acquired. Comparing with zymographic identification, morphological observation and physiological analysis, these seedlings were conformed as hybrid progenies. Further screening was conducted by indoor and outdoor trials on adverse condition-resistance and analysis of nutrient quality. A back-crossed strain with nice agronomic character was screened from numerous green seedlings of this hybrid combination, and named as MH3-1. The applying efficiency of MH3-1 in agricultural and husbandry production were introduced, its applying prospect in the future production of organic agriculture was analyzed.更多还原
