1. Selection of Pure Lines with Various Growth and Flowering Characteristics in Cyclamen
This experiment was carried out to select and evaluate for 150 inbred lines. The inbred lines with different flower colors and growth characteristics derived from several kinds of commercial cultivar were selected and self-crossed from 1999 to 2006. The inbred seedling lines were obtained from selfing crosses 4(S₄) or 5(S₅) generation using several cyclamen cultivars. The experiment was selected 30 pure lines of Cyclamen persicum seedlings showing different growth and flowering characteristics. Eleven lines including ‘cy99-20⁵’ flowered earlier than 330 days after sowing, however seven lines including ‘cy99-17⁵’ were flowered later than 340 days after sowing. The number of leaves of 27 lines including ‘cy99-6⁵’ were more than 30. The petal color of four lines including ‘cy99-6⁵’ was white, seven lines including ‘cy99-43⁵’ were red, four lines including ‘cy99-20⁵’ were violet, seven lines including ‘cy99-17⁵’ were pink, four lines including ‘cy99-28⁵’ were purple, and four lines including ‘cy99-27⁵’ were salmon. Flower diameter ranged from 3.5 cm to 11.7 cm, 27 lines including ‘cy99-6⁵’ were larger than 6.0 cm. The number of flowers of all lines was more than 9, eight lines including ‘cy99-20⁵’ were more than 20. All the lines of various growth and flowering characteristics would be very promising to use as breeding materials for F1 hybrids of Cyclamen persicum.
2. Final Selection of Lines and Combinations of Cyclamen with Middle or Big Flower Petal.
Final selected lines and combinations of various petal colors.
The 20 lines including‘cy98-7⁵' and 5 combinations including‘cy98-16⁵× cy98-10⁵ of cyclamen were selected finally with various petal color of middle or big size. The inbred lines and combinations were different flower colors and growth characteristics derived from several kinds of commercial cultivar. The selected lines and their combinations were showing uniform growth and flowering characteristics. They were excellent in growth and flowering characteristics compared to commercial cultivars.
In the petal colors, elevens including‘cy98-7⁵' showed red group(RHS 36-56), elevens including‘cy98-35⁵' showed red-purple group(RHS 57-74), cy98-3-1⁵' showed purple group(RHS 75-79), cy98-13⁵' and‘cy98-2⁵' showed white (RHS 155), The number of leaves of elevens including 'cy98-7⁵' were more than 50.
The number of flower in fifteens including ‘cy98-7⁵' were above 30.
Final selected lines and combinations of cold, heat, and disease tolerance: The 3 lines including‘cy98-1⁵' and 2 combinations of 'cy98-15⁵× cy98-16⁵’and ‘cy98-18⁵× cy98-17⁵’were selected finally with cold, heat, and disease tolerance. The number of flower of selected line 'cy98-1⁵' and ‘cy00-209⁴' were above 50.
Final selected lines of fragrance: The 3 lines including‘cy98-22⁵' were selected finally with fragrance. The number of flower of selected line ‘cy98-35⁵' was 43.
Final selected lines of early flowering: The 4 lines including‘cy98-25⁵' were selected finally with early flowering under 320 days from sowing. The number of flower of all selected lines were
above 50.
3. Final Selection of Cyclamen Lines with Small Flower Petal.
This experiment was carried out to select and evaluate for 27 inbred lines of small size of petal. The inbred lines with different flower colors and growth characteristics derived from several kinds of commercial cultivar were selected and self-crossed from 2000 to 2007. The inbred seedling lines were obtained from selfing crosses 3(S₃) or 4(S₄) generation using several cyclamen cultivars. Finally 5 lines were selected with various petal colors, cold, heat, and disease tolerance and
fragrance.
The 5 lines including‘00MN5-12-3-1’of cyclamen were selected finally with various petal color of small size. The selected lines were showing uniform growth and flowering characteristics with under 5.0cm petal diameter. In the petal colors, ‘00MN5-12-3-1’was white, '00MN5-12-7-3’was purple, '00MN3-5-5-12' was pink. Only line of ‘02G8-3-1-4’among 3 lines was selected finally with cold, heat, and disease tolerance. Only line of ‘02MV11-3-5’among 3 lines was selected finally with fragrance.
4. Final Cultivar Selection by Consumer Favorite Test of Breeding Cyclamen.
This work was conducted to evaluate finally for breeding line and combinations of cyclamen compared to commercial cultivars in the point of growth and flowering characteristics by assess meeting. The assess exhibited at the breeding greenhouse and auditorium of the Korean National Agricultural College on December 13, 2007. About 130 people attended the meeting consisted of cyclamen farmer, nursery and seed businessman, and agricultural researcher and officer.
Thirteen pure lines including ‘cy98-85⁵' and a combination ‘cy98-14⁵×cy98-12⁵' of middle or big petal cyclamen with different growth characteristics bred from Korean National Agricultural College were compared to 5 commercial cultivars including ‘Strauss’. And six pure lines including ‘Gyongicy cy-1’ of small petal cyclamen with different growth characteristics bred from Gyoungi Provincial Agricultural Research were compared to 6 commercial cultivars including ‘Metis-pink’.
Some selections of lines and combinations were excellent compared to commercial cultivar, number of leaves above 30 in growth characteristics and number of flower above 30 in flowering characteristics. They were also excellent degree of consumer favorite, and high price of survey. Therefore they are expected on cultivation and propagation in the future.
5. Seed Formation by Crossing Time and Methods of Cyclamen persicum
This experiment was carried out to evaluate the seed formation for the purpose of economical seed harvest in saving labor according to crossing time and methods with some inbred lines of Cyclamen persicum.
The ripening seed capsule and number of seed in a capsule were most excellent during January 1 to 10, early stage of flowering through crossing time from December 10 to January 30.
The normal pollination was much more ripening seed capsule and number of seed per capsule than that of bud or late riping pollen pollination. The seed formation by crossing and selfing was tested by 5 to 10 times of crossings. The ripening seed capsule and its seed number per capsule of selfing was very low compared to out crossings.
The out crossing had much more ripening seed capsule than that of selfing in the lines, above 80 percent and number of seed per capsule from 30 to 40.
6. Combining Ability and Correlations for Related to Growth and Flowering Characteristics in F₁ Hybrids by Diallel Cross of Cyclamen persicum
This study was conducted to determine combining ability and correlation among plant height, plant width, leaf length, leaf number, floret height, floret diameter, number of floret and peduncle length in 10 F₁ crosses made from the partial five-parent diallel cross in Cyclamen persicum. The plant height showed high positive correlations with number of floret and peduncle length. The mean squares of general combining ability (GCA) and specific combining ability (SCA) were highly significant for all the investigated characteristics. Variance component values of SCA were greater than those of GCA for all parameters, implying preponderance of non-additive gene actions for these characters. Relatively high GCA effects were obtained from the line of D for plant height and plant width, and the lines of A and D for floret diameter, peduncle length, and number of floret. Crosses of A×B, A×C, A×D, B×E and D×E exhibited high SCA effects on number of floret. The broad sense heritability was generally high as compared with narrow sense one. Particularly, number of floret showed high effects in narrow sense heritability.
