国外引进优良黄麻种质生物学鉴定与利用

Biological Evaluation and Utilization of Excellent Jute Germplasm Introduced

通过对从国外引进的12份黄麻优异种质进行3年的生物学鉴定,结果表明:引进种质大多为晚熟、绿茎、有腋芽,披针或卵圆形叶,生长较整齐。其中O-4叶片蜡质含量明显高于我国品种;O-5叶柄紧贴主茎。短光照处理未发现对光不敏感品种,但分期播种未见早花现象。所有品种在我国黄麻主产区均能正常生长与收获纤维,但晚熟品种只能在华南麻区才可收获成熟种子。

Biological evaluation of 12 excellent jute germplasm introduced have been carried out for continuous 3 years. The results showed that most of the germplasm were late mature, green stem, with axillary bud, lanceolate or ovate leaves and morphological uniformity. The leaf wax content of O-4 was markedly higher than any domestic variety, petioles of O-5 clinged to the stem. All the varieties were photoperiod sensitive varieties in the short day treatment, but when planted in the field, no early-flowering phenomenone was found. These varieties growed normally in main planting area, the late mature varieties could be harvested seeds only planted in south China.
