Abstract


Seedling offspring of this study to regale material, designed to provide a theoretical basis to regale seedling breeding, the seedling offspring in the garden and lily breeding work. Minjiang lily seeds, 1 year students real raw bulbs and 2-year students real raw corms were sown in sunlight greenhouse and exposed places, respectively, to get 1 year old, 2-year students and three years born offspring, using random sampling method phenophase and phenotypic traits of seedling offspring of observations. The experimental results are as follows: 1. Greenhouse and exposed ground 3 years raw real born offspring, respectively, there are 16.7% and 18.0% of the plants enter the reproductive growth, 2-year-old offspring, respectively, there are 5.1% and 1.4% of the plants enter the reproductive growth; Minjiang Lily seedling offspring plant height born offspring blades, the dynamic growth of the leaf area was \density from the bottom gradually decreases the leaf spacing increases gradually from the bottom; 2. corm weight, stem diameter and number of leaves showed significant or highly significant correlation with most other indicators; backbone height and corm weight and stem diameter rendering significant with or extremely significant with negative correlation; 3. Minjiang Lily seedling offspring height, stem diameter, number of leaves, leaf area and backbone height and other phenotypic traits of groups within the variation of the degree of performance for: under the same cultivation environment, matrix cultivated descendants of variation degree of greater than the offspring of garden soil cultivation; are soilless culture or garden soil cultivation conditions, the degree of variation within the greenhouse progeny population is greater than the offspring of the open field; the greenhouse environment matrix cultivation descendants the flower organ groups within the variation is less than the descendants of garden soil cultivation in open environment situation contrary, matrix cultivation conditions, greenhouse offspring of corolla width, style long and anther long three indicators of groups within the variation of the degree is greater than the descendants of the open field; garden soil cultivation conditions, except style length other trait groups variation The degree of performance for the the greenhouse future generations is greater than the descendants of the open field; degree of variability in the population is less than the degree of variation among populations. Minjiang Lily seedling breeding with a low-cost, fast breeding the corm weight than subsequent cases on behalf of traits is relatively consistent description regale sexual reproduction, and in fact, born offspring can be widely used in landscaping ; offspring phenotypic traits regale seedling variability exists in varying degrees, to provide a rich breeding direction for Lily breeding; experimental regale seedling variability of future generations more present in the inter-group, regale resources protection work to strengthen the protection of the populations.
