对8个国外引进高产红麻品种主要农艺性状的遗传研究表明,单株干皮重、单株鲜茎重、单株干茎重和单株纤维重的遗传力值为75.59～63.12％,遗传变异系数和遗传进度分别为19.46～10.66％和34.85～10.89％,严格选择效果明显。而株高、茎粗、皮厚、鲜茎出麻率的遗传力除茎粗外,仅30.23～53.09％,遗传异系数和遗传进度分别为2.03～7.56％和3.05～8.8％,严格选择效果不佳,可放宽选择尺度。纺织用品种的选育以干皮重、皮厚和茎粗为主,造纸用品种选育则以鲜茎重、株高和茎粗为主。
Genetic studies on the main agronomic traits of 8 high-yield kenaf cultivars in foreign countries showed that the heritability of dry weight per plant, fresh stem weight per plant, dry stem weight per plant and weight of single plant fiber was 75.59-63.12% The coefficient of variation and genetic progress were 19.46 ~ 10.66% and 34.85 ~ 10.89%, respectively. The effect of strict selection was obvious. The heritabilities of plant height, stem diameter, thickness and fresh stem yield were only 30.23-53.09%, genetic coefficient and genetic progress were 2.03-7.56% and 3.05-8.8%, respectively. The results of strict selection Poor, you can relax the choice of scale. Breeding of textile varieties with dry skin weight, thickness and stem thick-based, selection of papermaking varieties fresh stem weight, plant height and stem diameter based.
