Abstract:
Twenty-four Hippeastrum cultivars were used as materials to study the ornamental characteristics and the effects of different varieties on hybridization seed setting rate by periodic observation,in order to provide basis for the breeding of new varieties with independent intellectual property rights.The results showed that there were differences in ornamental charactersistic among different varieties.The flower color included red,pink,white,white and red;flower type covered single or double petals.Some cultivars such as ‘Trentino’ and ‘Merry Christmas’ had great differences on peduncle length,peduncle length of ‘Trentino’ and ‘Merry Christmas’ were 52.80 cm and 17.69 cm respectively,which made them good materials for cut-or pot-flowers.According to the principle of trait specificity and trait complementary,34 hybrid combinations were designed and the results of hybridization were calculated,‘Merry Christmas’‘Ferrari’ and ‘Red Lion’ had good seed setting rate,when ‘Merry Christmas’ was used as the female parent,the seed setting rate of the 5 crosses were all over 88.09%,and it became good parental materials for the future hybridization breeding.
