１９８９—１９９１年对黄麻栽培种圆果种（Ｃｏｒｃｈｏｒｕｓｃａｐｓｕｌａｒｉｓ）和长果种（Ｃ．ｏｌｉｔ－ｏｒｉｕｓ）选用了具有不同茎色和腋芽性状的材料做了６个组合，获得１３４株杂种Ｆ＿１苗。但苗株发根不良，在移栽后两周陆续死亡，最后幸存ＲＲ－５×（ＢＬ×７７－１９）Ｆ＿１组合中两株植株并开花、结果。Ｆ＿１均有腋芽，表现为父本的性状；花果形状偏向母本；茎色红同双亲。这两株的Ｆ＿２，茎色和腋芽性状分离成４种表现型：红茎或青茎有腋芽及红茎或青茎无腋芽。其中红茎有腋芽的生长较快。对种间杂交技术、亲本间的花粉与柱头亲和性、杂交花的胚珠受精情况及染色体构型等方面也作了观察、研究。
In 1989-1991, six combinations of materials with different stem color and axillary bud characteristics were selected for Corchoruscapsularis and C.olit-orius to obtain 134 hybrid F1 seedlings. However, the seedling plants had poor hair roots, and died two weeks after transplanting. Finally, two plants in the RR-5 × (BL × 77-19) F_1 group survived and flowered. F_1 have axillary buds, the performance of the male parent traits; flower shape biased mother; stem color red with parents. F_2, stem color and axillary buds of the two strains were separated into four phenotypes: axillary buds of red or green stems and axillary buds of red stems or stems. One of the red stem axillary buds grow faster. The interspecific hybridization technology, pollen and stigma affinity between parents, hybrid flower ovule fertilization and chromosomal configuration were also observed and studied.
