磷高效水稻培育是提高土壤潜在磷利用效率的一种途径,用云南主栽粳稻品种合系35与云南稻种核心种质耐低磷特性极强老来红配制P1,P2,F1和F2世代,在云南省农科院(海拔1916 m)种植两处理(有效磷质量比6.26 mg/kg,有效磷40 mg/kg)耐低磷鉴定,采用数量性状的主基因-多基因混合遗传模型,研究了水稻的分蘖、株穗重和总干重3个耐低磷指标性状的遗传,结果表明,分蘖、株穗重和总干重3个耐低磷指标性状在这个组合中都表现为一对主基因加多基因遗传和多基因遗传2种遗传模式.
Phosphorus-efficient rice cultivation is a way to improve the potential phosphorus use efficiency in soils. P1, P2, F1 and F2 generations were prepared with the combination of Yunnan main rice variety 35 and Yunnan rice core germplasm with extremely low phosphorus tolerance , The two major treatments (effective phosphorus content 6.26 mg / kg, available phosphorus 40 mg / kg) were appraised to be resistant to low phosphorus in the Yunnan Academy of Agricultural Sciences (1916 m above sea level). Quantitative trait gene- The inheritance of tillering, panicles per panicle and total dry weight of three low-phosphorus-tolerant traits in rice was studied. The results showed that the three traits of tillering, panicle weight, The main gene plus polygenic and polygenic inheritance of two genetic models.
