不同早熟水稻品种的适应性鉴定研究

Study on Adaptability Identification of Different Early Maturing Rice Varieties

为了筛选出适合黑龙江省绥化北部地区早熟优良水稻种质资源,丰富该地区水稻种质资源,为当地水稻种植品种选择提供依据。研究通过比较品种的物候期、生育特性、抗逆性状、产量及其构成因素,对7个水稻品种进行适应性鉴定,从中选择抗病性强、优质、高产新品种。结果表明,7个水稻品种抗逆性强、抗病性强,但产量受到平方米有效穗数、每穗实粒数、结实率等因素间的协同影响,从产量上看,惠生5和承泽1适应当地种植。

In order to screen out early-maturing excellent rice germplasm resources suitable for northern Suihua,Heilongjiang Province,the germplasm resources of rice in this area will be enriched to provide the basis for the selection of local rice varieties.By comparing the phenological period,growth and development characteristics,stress-resistant characters,yield and its components of seven early-maturing rice varieties,the adaptability identification was carried out,new varieties with strong disease resistance,high quality and high yield were selected.The results showed that the seven rice varieties had strong resistance to stress and disease,but their yield was synergically affected by effective panicles per square meter,grain number per panicle and seed setting rate.In terms of yield,Huisheng 5 and Chengze 1 were suitable for local planting.
