对江西引进巴西陆稻晚季种植的试验数据进行了多角度、多方位（标准误、单元回归、多元回归、通径分析、灰色关联）的计算机统计分析。结果表明：（１）易旱二晚田二晚栽培的关键产量性状是基本苗、有效穗、全生育期天数；（２）秋闲田（地）二晚栽培的关键产量性状是结实率、有效穗、播种至始穗天数；（３）不论何种稻作方式，始穗至成熟天数和千粒重受环境影响小，是典型的受基因控制的遗传性状（即种性）。 The statistical analysis of multi-angle and multi-directional (standard error, unit regression, multivariate regression, path analysis, gray relation) experimental data on the planting of late-season Brazilian Upland rice in Jiangxi was conducted. The results showed that: (1) The key yield traits of two nights in drought-prone and two late-night fields were basic seedling, effective spike and full growth period; (2) Effective panicle, sowing to the beginning of the ear number of days; (3) Regardless of the type of rice cultivation, the number of days from ear initiation to maturity and 1000 grain weight is less affected by the environment, is a typical genetic controlled genetic traits (ie, sex).
