摘要:

本研究旨在筛选出高产、优质和适宜宁夏南部山区种植的胡麻高亚麻酸材料。采用随机区组设计,以引进的13份胡麻高亚麻酸突变体材料为试材,采用实验室考种和近红外分析技术测定农艺性状、产量性状和品质性状,对其生产性能和品质性状进行综合分析。结果表明,参试材料的籽粒产量居前3位的是Z-M-865、Z-M-415和Z-M-215,产量分别为3569.07 kg/hm2、3406.10 kg/hm2和3326.74 kg/hm2。Z-M-865的单株结果数、每果粒数、单株产量和主茎分枝数都最高,分别为19.64个/株、8.40粒/果、0.92 g/株和7.29个/株;Z-0-300的株高和工艺长度最高;Z-M-585的千粒重最大。相关性分析表明胡麻籽粒产量与主茎分枝数、单株结果数、单株产量呈显著正相关(P<0.05)。参试材料的亚麻酸含量为46.06%~56.05%,亚麻酸含量大于50%的材料有6份。通过生产性能和品质性状综合分析,发现突变体材料Z-M-865、Z-M-415和Z-M-350在宁夏南部山区的籽粒产量表现较好,含油率高,且亚麻酸含量在50%以上,适宜宁夏南部山区种植。

Abstract:

The study aims to screen out high-yield, high-quality and suitable flax high linolenic acid materials for planting in the mountainous areas of southern Ningxia. In this study, 13 flax high linolenic acid mutant materials were used as test materials. The agronomic traits, yield traits and quality traits were determined by laboratory test and near infrared analysis technology, and the production performance and quality traits were comprehensively analyzed. The results showed that Z-M-865, Z-M-415 and Z-M-215 had the highest grain yield of 3569.07 kg/hm2, 3406.10 kg/hm2 and 3326.74 kg/hm2, respectively. The fruit number per plant, grain number per fruit, yield per plant and branch number of main stem of Z-M-865 were the highest, which were 19.64/plant, 8.40/fruit, 0.92g/plant and 7.29/plant, respectively. The plant height and process length of Z-0-300 were the highest. The 1000-grain weight of Z-M-585 was the largest. Correlation analysis showed that the seed yield of flax was significantly positively correlated with the number of main stem branches, the number of pods per plant and the yield per plant (P< 0.05 ). The linolenic acid content of the tested materials was 46.06%~56.05%, and there were 6 materials with linolenic acid content greater than 50%. Through the comprehensive analysis of production performance and quality traits, it was found that the mutant materials Z-M-865, Z-M-415 and Z-M-350 had better grain yield, high oil content and linolenic acid content in the southern mountainous area of Ningxia. The content of linolenic acid was above 50 %, which was suitable for planting in the southern mountainous area of Ningxia.
