- 摘要:
- 吉育612是利用“三系”法选育的大豆杂交种，不育系为JLCMS57A，恢复系为JLR9 。吉育612的主要特点是高产、稳产、品质较好、抗病性强。两年区城试验平均较对照增产16.0%，生产试验较对照增产4.4%。人工接种鉴定抗大豆花叶病毒病，高抗大豆灰斑病。籽粒脂肪含量20.92%，蛋白质含量42.07%。吉育612制种必须选择干旱少雨，有灌溉条件，天然昆虫群体多的地区。父母本错期播种，种植比例为1∶2或1∶3，密度为15万株?hm-2。可利用蜜蜂进行传粉，整个生育期严格去杂去劣，确保种子纯度。
- Abstract:
- Jiyu 612 is a high-yield and quality ‘double-high’ soybean hybrid which was selected by the ‘three-line’ method. The maternal sterile line is JLCMS57A, and the parental restorer line is JLR9. The main characteristics of Jiyu 612 are high and stable yield, good quality and strong disease resistance. In the two-year regional trials, the average yield increased by 16.0% compared with the control variety, and the production trial increased by 4.4% compared with the control variety. Jiyu 612 is resistance to soybean mosaic virus disease and high resistance to soybean gray spot disease by artificial inoculation identification. The grain fat content is 20.92% and the protein content is 42.07%. Jiyu 612 seed production must be with drought, less rain, irrigation conditions. And the plant areas must be with many natural insect populations. Parents must be planted at different times with planting ratio of 1∶2 or 1∶3 and density of 150 000 plants?ha-1. Honey bees also can be used for pollination, and the mixed and inferior plants must be strictly removed during entire growth period to ensure the purity of the seeds.
