摘要
利用从陆海棉种间杂交后代筛选的铃形各不相同的5个自选系,通过连续5年观测棉铃10个性状的表现得知:除子指外,其余9个性状均有较高的遗传力。用5个自选系作亲本进行轮回杂交结果,各性状F_1均有不同程度的正向优势,其中铃体积具有较强的超高亲优势,纵径、铃形指数、衣分、绒长和铃容重等性状还具有母体优势效应。
Phenotype for 10 characters of the cotton boll was observed for 5 years in 5 sys-tems.There are different shapes of cotton bolls which were selected between G. hirsutumwith G. barbadense. All the 9 characters have higher heritability except the seed index,5systems were crossed reciprocally.Result showed that each character of F_1 has differentand positive heterosis on certain extent,among them the volume of the cotton boll hasover-hish-parent heterosis,and the vertical diameter,the shap index of cotton boll,thelint rate,the fiber length and the unit weight of cotton boll have maternal heterosis effect.
