摘要:
为探讨杂交大豆制种最佳的父母本行比、行距配置，提高制种产量，以大豆细胞质雄性不育系JLCMS34A和恢复系JLR11为材料，于2011和2012年在吉林省洮南市进行田间试验。试验设45 cm和65 cm 2种行距，父母本1∶1、1∶2、1∶3和1∶4共4种行比，研究了8种处理对制种产量的影响，并对构成产量的主要因素进行分析。结果表明：行距45 cm的制种产量显著高于65 cm行距处理，并随着母本行数增加，制种产量显著提高；以行距45 cm、父母本行比1∶4处理的制种产量（1 396.7 kg·hm-2）最高，较行距65 cm、父母本行比1∶2的常规种植模式提高35.0%。在吉林省洮南地区适当缩小垄距、增加母本行数可减少单株荚数和单株粒数，增加百粒重，并显著提高制种产量。
Abstract:
A field experiment was conducted to investigate the best parents planting configuration on seed production of hybrid soybean.The experiment was conducted with two levels of row spacing(45 and 65 cm)each at four levels of male to female row ratio(1∶1,1∶2,1∶3 and 1∶4)in 2011 and 2012 in Taonan area,Jilin province,with JLCMS34A and JLR11 as female and male parent,respectively.Hybrid seed yield in 45 cm row space was higher than 65 cm.Seed yield increased with the increasing of female parent rows.Highest yield of 1 396.7 kg·ha-1was obtained under 45 cm row spaces and parents row rates of 1∶4,increased by 35% compared with the traditional planting pattern of 65 cm row spaces and parents row rates of 1∶2.Results suggest that reducing row space and increasing female parent row ratio could decrease pods and seeds per plant,enhance 100-seed weight,and hence increase seed yield.
