全球水稻分子育种计划核心种质苗期耐低磷资源的鉴评与筛选

Evaluation and Screen of the Core Germplasm of Integrated International Molecular Breeding Program for Low-phosphorous Tolerance in Seedling

苗期低磷胁迫水培试验表明 :全球水稻分子育种计划核心种质对低磷营养胁迫的调节能力存在着显著的基因型差异 ,表现在分蘖能力、根长、根重等性状明显不同。通过对低磷营养胁迫下水稻根茎性状表现的评价 。

This experiments treated with the tolerance to low-phosphorous in the rice seedling in water culture, the results showed the rice seedlings of core germplasm of integrated international molecular breeding program had obviously difference tolerance to low-phosphorous. According to the character performances of rice seedling, the varieties with good tolerance to low-phosphorousthe were screened.
