摘要:

目的 厘清品种、地点、气象因素和镉含量对花生种用品质的影响,并开发花生种用品质相关标记,为提高花生种用品质和实现花生高产稳产的产业目标提供依据。 方法 采用不同花生品种在北方区进行多点试验,对花生种用品质进行方差分析和多重比较;以种用品质指标为因变量、气象因子为自变量进行逐步回归分析;对籽仁镉含量与种用品质指标间的相关性进行分析;运用关联分析发掘花生种用品质相关分子标记。 结果 品种、地点、气象因素及其互作对花生种用品质的影响均达极显著水准。种植大粒花生的10个地点中,青岛发芽势、发芽率及发芽指数高于其他地点,唐山活力指数高于其他地点。种植小粒花生的12个地点中,青岛发芽势高于其他地点,青岛和唐山发芽率高于其他地点,青岛发芽指数和活力指数高于其他地点。大粒花生镉含量与4项种用品质指标存在显著或极显著负相关关系;在一定范围内,镉含量与小粒花生发芽指数存在着极显著正相关关系。利用标准发芽试验统计的4个种子活力性状数据与60对AhTE标记进行关联分析,选用的标记覆盖全部的花生20条染色体组,共发掘9个与花生种用品质显著相关的分子标记。 结论 品种、地点、气象因素和镉含量对花生种用品质均存在显著的影响,共获得9个与种用品质性状相关的分子标记。

Abstract:

Objective To understand the effects of variety, location, meteorological factors and cadmium content on the quality of peanut seeds, develop quality markers for peanut seeds, improve the quality of peanut seeds, and achieve the industrial goal of high and stable yield of peanut. Method In this study, different peanut varieties were tested in the northern region, and the quality of peanut seed was analyzed by variance analysis and multiple comparison. With species quality index as dependent variable and meteorological factor as independent variable, stepwise regression analysis was carried out. The correlation between cadmium content of seed kernel and seed quality index was analyzed. Correlation analysis was used to explore molecular markers related to quality of peanut seed. Result Varieties, locations, meteorological factors and their mutual effects on the quality of peanut species were very significant. The germination potential, germination rate and germination index in Qingdao were higher than those in other places, and the vitality index in Tangshan was higher than those in other places. Among the 12 small-peanut planting sites, the germination potential of Qingdao was higher than that of other sites, the germination rate of Qingdao and Tangshan was higher than other sites, and the germination index and vitality index of Qingdao were higher than other sites. There was significant or extremely significant negative correlation between cadmium content and 4 seed quality indexes of large peanut. There was a significantly positive correlation between cadmium content and germination index of small peanut in a certain test range. Four seed vitality traits from standard germination tests were correlated with 60 pairs of AhTE markers. The selected markers covered all 20 chromosome sets of peanut, and 9 molecular markers were found to be significantly correlated with peanut seed quality. Conclusion There are significant effects of varieties, locations, meteorological factors and cadmium contents on peanut seed quality. Nine molecular markers related to seed quality traits are obtained.
