以水稻矮生性近等基因系为试材,经花药培养获得花粉植株,比较研究了各种不同矮生性基因在单倍体和二倍体水平上的性状表现结果表明:各种不同矮生性近等基因系的愈伤组织诱导率和绿苗分化率显著不同;染色体数目和基因剂量,与矮生性基因的特异性共同决定矮生性单倍体的表型特征;矮生性单倍体形态特征的变异因性状性质(量测性状、计数性状和比值性状)的不同而不同;单倍体各性状的表型值与二倍体亲本的表型值密切相关。 The rice dwarfing near-isogenic lines were used as materials to obtain pollen plants by anther culture. The characters of haploid and diploid of different dwarfing genes were comparatively studied. The results showed that: The callus induction rate and the differentiation rate of green plantlets were significantly different among other isogenic lines. The chromosome number and gene dosage, together with the specificity of dwarfism genes, determined the phenotypic characteristics of dwarf haplotypes. The morphological characteristics of dwarf haploid Variation varies with the nature of the trait (measured trait, count trait, and ratio trait); the haplotype traits are closely related to the phenotypic values ​​of diploid parents.
