摘要:

为探明寒地早粳稻超高产株型特征,选用700~800 kg/667 m2、600~700 kg/667 m2、500~600 kg/667 m2和400~500 kg/667 m2 4个产量水平的48个主栽品种和苗头品系,研究其穗型、叶片和茎秆特征的差异。结果表明,700~800 kg/667 m2水平的早粳稻每穗干质量和着粒密度较高,剑叶、倒2叶和倒3叶叶基角及剑叶披垂度大,后4片叶的叶长序表现为倒2>倒3>倒4>剑叶,剑叶、倒2叶、倒3叶和倒4叶较宽,在合理范围内增加株高,但必须缩短倒4节间长度。相关分析表明,产量与每穗干质量、剑叶和倒2叶叶宽、倒3叶叶长和叶宽、倒4叶叶长和叶宽呈极显著正相关,与秆长、抽穗期和蜡熟期株高呈显著正相关。

Abstract:

The objective of the study was to determine the plant-type characteristics of super high yielding early japonica rice. In this study, panicle traits, leaf traits, and culm traits of plant were investigated using 48 rice cultivars and advanced lines from Heilongjiang Province at grain yield levels of 700-800 kg/667 m2, 600-700 kg/667 m2, 500-600 kg/667 m2, and 400-500 kg/667 m2. The results showed that the plant-type characteristics of super high yielding early japonica rice were as follows: higher spike weight and density of panicle, wider flag leaf, second leaf from top, third leaf from top and fourth leaf from top with great basic angle and dropping angle, second leaf length from top﹥ third leaf length from top﹥fourth leaf length from top﹥flag leaf length, higher plant height in certain extent, and shorter top fourth internode. The correlation analysis results showed that yield was significantly positively correlated with spike weight, density of panicle, width of flag leaf and second leaf from top, third leaf length and width from top, and fourth leaf length and width from top, positively correlated with culm length, and plant height at heading stage and dough grain stage.

Key words: early japonica rice, super high yield, plant-type characteristics, cold region
