培矮64s/E32于1998年早季在广州进行试种试验。该组合株高115.8cm,秆高105.4cm,叶片厚直,呈瓦状,叶色较深;后期上部三片功能叶平均长度53.8cm,开张角度较小,不早衰,显示出良好的株型;其全生育期为139d,属华南早籼稻的中熟组合类型。在单株植、土壤肥力中下条件下,有效穗为210万/hm2,分蘖力偏弱,穗较大,单穗湿重为 5.42 g,结实率 80.6％,千粒重21.2g,收获指数中等,为 0.537,实收产量为7650 kg hm-2。 Pei-dai 64s / E32 in early 1998 trial planting in Guangzhou. The combined plant height was 115.8 cm and culm height was 105.4 cm. The leaves were thick and straight, with a tile-like shape and deep leaf color. The average length of the upper three functional leaves was 53.8 cm in the late stage, with a small opening angle and no premature aging, indicating a good plant type The whole growth period was 139 days, belonging to the middle-maturing combination type of early indica rice in South China. Under monocropping and soil fertility, the effective panicle was 2.1 million / hm2, the tillering ability was weaker and the spikelet was larger. The single panicle wet weight was 5.42 g, the seed setting rate was 80.6%, the grain weight was 21.2 g, the harvest index was medium, 0.537 and the actual yield was 7650 kg hm-2.
