从中籼区试结果看安徽省水稻发展趋势

The Development Trend of Rice in Anhui Province Through Medium Indica Rice from Regional Trials

为了研究安徽省中籼稻产量的发展变化趋势,以安徽省2007—2011年区试的439个品种为材料,通过分析参试品种的产量水平及各产量性状间的相关性,研究影响安徽省中籼稻产量变化的主要影响因子。研究结果表明,安徽的育种水平在不断的进步,育成的品种(组合)的产量水平在不断的提升;产量因子的相关性分析结果表明:应当在保证结实率的基础上,提高穗粒数和有效穗,这样才能达到高产和稳产的目的。研究的结果为安徽省中籼杂交水稻组合的选育提供重要参考。

In this paper, 439 species of regional trials rice from 2007 to 2011 were studied to analysis the correlation of yield level varieties and traits in order to study the medium indica rice development trend of rice production in Anhui Province. We studied the main factors that influence the effect of changes of indica rice production in Anhui Province. The results showed that, breeding level was constantly progress , production levels of breed varieties （combination） was continuous improve in Anhui. The correlation of yield factor showed that： to achieve the purpose of high and stable yield we should increase grain number per panicle and productive panicle based on the guarantee of seed setting rate. The results provide an important reference for the breeding of middle-season indica Hybrid Rice in Anhui Province.
