我所根据76年秋全国烟草育种协作会议的精神和任务,于当年把烤烟育种列为重要科研课题之一.在把当地种植多年的老品种“401”加以提纯复壮的同时,对新从山东烟科所和地区农科所引进的10个品种,以“401”作父本于77年搞成10余杂交组合,并且进行了花粉单倍体培育. 1、对当地种植多年的401品种进行系统选育提纯复壮.“401”原是全国有名的优质品种之一,当地普遍种植,所以这是永定烤烟品质优良的基础.但由于多年没有提纯复壮,已产生退化和混杂现象.为了保证优质,提高种性,去年采取单株选育办法,从大田选择茎粗叶茂,株型良好,具有原品种特性的植株留作种株.通过这样选择留下的种子,今年生长整齐,叶片增多(比原来增加10～12片),品质也优良.从而可以进一步
According to the spirit and mission of the National Tobacco Breeding Symposium in Autumn of 2006, one of the important scientific research topics was to make tobacco breeding one of the important research topics in the year. While refining and rejuvenating the old variety “401” planted locally for many years, The institute introduced 10 varieties introduced by local agricultural science institutes and made “401” as the male parent to develop more than 10 hybrid combinations in 77 years, and carried out the pollen haploid cultivating. (1) 401 cultivars cultivated locally for many years were systematically “401” was originally one of the well-known national high-quality varieties, widely planted locally, so this is the basis for the excellent quality of Yongding flue-cured tobacco. However, many years have not been purified and rejuvenated, have produced degradation and mixed.In order to ensure high quality, Improve the species, last year to take single plant breeding methods, from the field selection stem thick leafy, plant type is good, with the original varieties of plants reserved for seed plants. By so choose to leave the seeds, growing neat this year, the leaves increased Than the original increase of 10 to 12), quality is good. Thus you can go further
