During the present investigation, eight commonly grown rice varieties of temperate highland regions of Kashmir were selected to study different quality attributes. The dimensional and physical properties of selected rice varieties differed significantly (p≤0.05). With regard to colour coordinates (L*, a*, b*, chroma and hue angle), all the varieties showed significant (p≤0.05) variation except b* value. Very high significant (P≤0.01) correlations were noticed amongst the different dimensional and physical attributes. Based on the nature and magnitude of character association recorded in the present study, the inference drawn was that dimensional properties like length, width, L/W ratio, thickness, equivalent diameter (De), geometric diameter (Dg), arithmetic diameter (Da), area of transverse surface (At), surface area (S) and aspect ratio (Ra); physical properties like 1000 grain weight, bulk density (BD), true density (TD), hardness and chalkiness should be used to formulate the selection indices for development of quality rice for temperate highland regions.

温带高原水稻品种的尺寸和物理特性

在本次调查中，选择了克什米尔温带高原地区的8个常用水稻品种来研究不同的品质属性。所选水稻品种的尺寸和物理特性差异显着（p≤0.05）。关于颜色坐标（L *，a *，b *，色度和色相角），除b *值外，所有品种均表现出显着（p≤0.05）变化。在不同的尺寸和物理属性之间发现非常高的显着相关性（P≤0.01）。根据本研究中记录的字符关联的性质和大小，得出的推论是长度，宽度，长宽比，厚度，等效直径（De），几何直径（Dg），算术直径（Da）等尺寸属性），横断面积（At），表面积（S）和长宽比（Ra）;
