摘要
为筛选适应湖南生态区大面积推广的芝麻品种,在湖南长沙、怀化对赣芝系列12个芝麻品种开展引种试验,结果表明:赣芝系列芝麻品种的单株产量表现出极显著的地域差异,长沙的增产潜力更高,长沙点的黑芝麻品种单产显著高于怀化;白芝麻品种单株蒴数和单株产量都表现出极显著的地域差异;丰产性最好的黑芝麻品种是赣芝19号,白芝麻品种是赣芝12号;赣芝 9 号、赣芝 10 号、赣芝 14 号、赣芝 18 号、赣芝 11 号、赣芝 19 号、赣芝 20 号表现高产、抗倒、抗病、成熟期蒴果轻度开裂,可在湖南各生态区进行生产试验,赣芝 12 号、赣芝 15 号、赣芝 17 号较对照增产幅度超过 20%,但植株倒伏,可进一步进行多点小区试验.
Abstract
In order to select sesame varieties suitable for large-scale promotion in Hunan ecological regions,introduction experiments of 12 sesame varieties of Ganzhi series were carried out in Changsha and Huaihua,Hunan Province.The results showed that the yield per plant of Ganzhi series sesame varieties showed significant regional differences,and the yield potential of Ganzhi series sesame varieties in Changsha was higher.The yield per unit of black sesame varieties in Changsha was significantly higher than that in Huaihua,and the number of capsules per plant and the yield per plant of white sesame varieties showed significant regional differences.The yield of Ganzhi 19 was the highest in black sesame varieties,and the yield of Ganzhi 12 was the highest in white sesame varieties.Ganzhi 9,Ganzhi 10,Ganzhi 14,Ganzhi 18,Ganzhi 11,Ganzhi 19,Ganzhi 20 showed high yield,lodging resistance,disease resistance,and slight capsule cracking at the maturity stage,and could be used for production tests in various ecological regions of Hunan Province.Although the yield of Ganzhi 12,Ganzhi 15 and Ganzhi 17 increased by more than 20%compared with the control,the plants were lodging.Hence,further multi-point plot tests should be carried out.
