摘要
本研究的目的是根据“绿色质量生产力”和“干物质生产力”的性状,估计线性回归系数、抗逆性、遗传柔韧性和稳定性等适应性参数。本研究以“顿斯科伊”农业研究中心培育的6个红豆品种为研究对象。品种“Zernogradsky 2”被作为标准品种。播种在春季进行,SSFC-7播种机在其纯形式,没有覆盖作物。播种率为每公顷500万颗发芽种子。地块面积为20平方米,重复四次。根据生态适应性指标进行估算,参照S. A. Eberchart和W. A. Russel(1966)和V. A. Zykina et al.(2011),计算抗逆性和遗传灵活性,参照A.A. Goncharenko(2005)。方差分析结果表明,因子B(条件)对绿质生产力变异率(79.12%)和干物质生产力变异率(75.38%)均有显著影响。所有红豆品种按年份和播种情况均显著超过标准品种的指标。其中产量最高的新品种“Atamansky 20”,平均绿重30.9 t/ha,干重8.3 t/ha,历年波动分别为24.8 ~ 44.9 t/ha和6.4 ~ 12.1 t/ha。红豆品种的绿色和干质量生产力对变化的环境条件的响应不同。品种“Zernogradsky 2”、“Atamansky”和“Atamansky 20”在绿色饲料和干草栽培时需要改善条件(bi bbbb1),而品种“Veles”、“Sudar”和“Shuravi”对改善环境条件的反应较差,适应性较强(bi < 1)。品种“Veles”、“Sudar”和“Shuravi”具有较强的抗逆性,而品种“Zernogradsky 2”、“Atamansky”和“Atamansky 20”的抗逆性适应能力范围较窄。品种“Atamansky 20”的基因型与环境因子的对应关系较高,遗传灵活性较高。
Results of estimating adaptability of sainfoin varieties in the south of the Rostov region
The purpose of the study was to estimate such adaptability parameters, as a linear regression coefficient, stress resistance, genetic flexibility and stability coefficient, according to the traits “green mass productivity” and “dry matter productivity”. The objects of the study were 6 sainfoin varieties developed by the ARC “Donskoy”. The variety ‘Zernogradsky 2’ was taken as the standard one. Sowing was carried out in the spring with the SSFC-7 seeder in its pure form, without a cover crop. A seeding rate was 5 million germinated seeds per 1 ha. The area of the plot was 20 m2, with fourfold repetition. The estimation according to the indicators of ecological adaptability was performed according to the S. A. Eberchart and W. A. Russel (1966) as presented by V. A. Zykina et al. (2011), calculation of stress resistance and genetic flexibility was established according to A.A. Goncharenko (2005). The results of the analysis of variance have shown a significant influence of factor B (conditions) both on the variability of productivity of green mass (79.12 %) and dry matter (75.38 %). All the studied sainfoin varieties according to the years and sowing significantly exceeded the indicators of the standard variety. The most productive of them, the new variety ‘Atamansky 20’, formed on average 30.9 t/ha of green mass and 8.3 t/ha of dry mass, with fluctuations over the years, respectively, 24.8–44.9 t/ha and 6.4 –12.1 t/ha. The sainfoin varieties differ in the response of green and dry mass productivity to changing environmental conditions. The varieties ‘Zernogradsky 2’, ‘Atamansky’ and ‘Atamansky 20’ demand to improve conditions when cultivated for green feed and hay (bi > 1), while the varieties ‘Veles’, ‘Sudar’ and ‘Shuravi’ respond less well to improved environmental conditions and are more adaptable (bi < 1). The varieties ‘Veles’, ‘Sudar’ and ‘Shuravi’ are highly resistant to stress, while the varieties Zernogradsky 2’, ‘Atamansky’ and ‘Atamansky 20’ have a narrower range of adaptive capabilities of stress resistance. A higher correspondence between a genotype and environmental factors and high genetic flexibility were found in the variety ‘Atamansky 20’.
