摘要:
为使我国野生百合资源用于新品种培育中，对收集的部分野生百合进行了自交、种间杂交及与栽培品种的杂交，较为系统地评价了野生百合资源的亲和性。结果表明：1）野生百合自交亲和性普遍较好，细叶百合、宜昌百合、岷江百合自交子房膨大率分别达到了100％、66.7％和11.1％。2）以卷丹、泸定百合、岷江百合、兰州百合和青岛百合为母本时，各杂交组合的子房平均膨大率分别达到了53.1％、50.0％、50.0％、45.2％和20.0％，表现出了较高的亲和性；以岷江百合、泸定百合和川百合为父本时，杂交组合的子房平均膨大率分别达到了50.0％、35.0％和10.0％,可作为杂交育种的亲本材料。3）百合组的野生种与新铁炮百合和东方百合杂种系的品种有较高的亲和性；卷瓣组的野生种与亚洲百合和新铁炮百合有较高的亲和性。4）子房切片培养和胚珠培养的成功率、杂种苗的获得率及有胚率与前期子房的膨大率及子房膨大维持天数有一定的相关性，说明子房膨大率可作为评价百合杂交亲和性的指标之一。
Abstract:
In order to use wild lily resources for new cultivar breeding, the cross compatibilities of partial wild lilies were evaluated by self\|crossing, inter\|specific crossing and crossing between varied species and cultivars. Main results were obtained as follows: 1) the swollen fruit rates in selfing of Lilium pumila, L. laucanthum and L. regale reached 100％, 66.7％ and 11.1％ respectively. 2) When L. lancifolium, L. sargentiae, L. regale, L. davidii var. unicolor and L. tsingtauense were used as female parents, the average swollen fruit rates reached 53.1％,50.0％,50.0％,45.2％ and 20.0％ respectively. While as male parents, the average swollen fruit rates of L. regale, L. sargentiae and L. davidii were 50.0％, 35.0％ and 10.0％ separately. The results indicated that these several species were valuable for lily crossbreeding. 3) The compatibilities between species belonging to Sec.Leucolirion and cultivars of Oriental hybrids and Lilium×formolongi and those between species belonging to Sec.Sinomartagon and cultivars of Asia hybrids and Lilium×formolongi were higher; 4)The relationship between swollen fruit rate and the survival rate of ovary slices and hybrid seedlings indicates that the swollen fruit rate can be used as one of standards to show the cross compatibility among lily crosses.
