Hemerocallis Species Selection And Seed Production Technology

In this paper, Selected according to market demand for cultivation in Suzhou Hemerocallis,On the selected Hemerocallis seed production and breeding research, main conclusion following:1. The introduction of the 207 Hemerocallis track materials through color, resistance, plant height, flowering duration and other characteristics of the evaluation, identification of areas suitable for the growth of fine varieties of Suzhou,16, of which 5 species of evergreen, large 6 varieties of flowers, long flowering varieties 2,1 dwarf varieties,2 varieties of complex valve.2. On Hemerocallis inbred and hybrid varieties of seed set and Statistics, results showed that the crosses with parents of the seed set of the selection, sf-6 * j-1 have high seed setting rate than the other varieties. The n-4, p-24, nz-51, sf-2, nzy-1 regardless of field cultivation, or cultivation, artificial or natural pollination pollination are not strong; in solid varieties, in addition to sf-6 outside the breed Other varieties of artificial pollination is higher than open pollinated; facilities is higher than cultivated field cultivated fruit setting rate.3. Measured in Hemerocallis of 11 species, differences in fruit size, fruit length at the 1.35-3.13cm long axis between the short axis length of the fruit between the 0.98-2.45cm, the number of individual seeds within the fruit of 3 -11 stars, grain weight between the 28.0-86.2g. The fruits of which the largest p-24, the largest number of single fruit seeds, seed grain weight is the heaviest.4. Different varieties of seed germination Hemerocallis in different species germination rate can reach 70%, the same species planted in the highest germination rate by the end of August, under the same conditions, obtained by cultivation in the field in seed germination rates than obtained Seeds high. Hybrids in different sowing dates harvest the same time, the germination rate is insignificant, since the early delivery of seed germination to harvest than later.5. By j-1 * sf-6, sf-2, n-5 seedlings of three varieties of the investigation, the seed harvest at different times on different growth potential of seedlings, pre-picked a good pick at a later stage, obtained by sowing sf -6 descendants of this species to maintain the maternal characteristics, variability is small, you can get large quantities of seed to seed propagation.
