STUDIES OF F1 POPULATION FROM CROSSING OF POMPOM TYPE WITH SINGLE AND DOUBLE TYPE OF KEMBANG KERTAS (ZINNIA elegans jacq.)

The shape of kembang kertas which is attractive as cut flowers is pompom type. Research to get F1 of pompom type with greater proportion was conducted through crossbreeding. Pompom type of kembang kertas is not perfect flowers (do not have male reproductive organ), so it is needed to determine which type of male (single and double type) of perfect flowers (there are male and female reproductive organs) that can give greater pompom proportion. The purpose of this study is to determine the appropriate type of male to get a descent pompom. The materials used in this study were female parents of pompom type that originated of selfing results of M6 population (M6S1) and male parents of single and double type of M7 population. The results showed that crossing between ♂double x ♀pompom types produced the pompom type flower to the proportion of 0.78 and crossing between ♂single x ♀pompom produced the pompom type flower at the proportion of 0.31.
