【摘要】 以3个迟熟亲本与3个早熟亲本配制3个组合7个世代,即P₁、P₂、F₁、rF₁、F₂、B₁、B₂,研究了5个主要生育阶段的显性度、遗传力、遗传进度。结果表明:在中早期世代选择效果依次为:初花>抽苔>成熟>终花>现蕾,初花是最佳选择时期。更多还原

【Abstract】 The deminance, heritability and genetic advance were studied in the main five growing-stages through three combinations and seven generations (P, P, F, rF, F B, B) which were from three early maturing and three late maturing varieties intercrossed.The result showed that the order of selecting effect in the medium and late period was first-flowering>peduncle-growing>mature>late-flowering>budding, The first-flowering was best.更多还原
