Commercial Cultivar Breeding of Spreading Petunia and Their Propagation
1. Selection of Pure Lines and F₁ crosses with Various Growth and Flowering Characteristics in Spreading Petunia
Selection of Pure Lines
The inbred lines with different flower colors and growth characteristics derived from several kinds of commercial cultivar and private collections were selected and self-crossed from 1999 to 2008. The inbred seedling lines were obtained from selfing crosses 7(S₇) or 6(S₆) generation using several spreading petunia cultivars. The surfinia lines were selected 72 including 'Pe99-108⁷', and wave petunia 94 lines including 'Pe99-020⁷'. They were showing different growth and flowering characteristics.
Selection of 39 Pure Lines and 10 F₁ Crosses in Surfinia Petunia
In surfinia petunia, twenty three lines and 10 F₁ crosses including ‘Pe99-017⁷’were middle or large flower petals, twelve lines including ‘Pe99-018⁷’were small flower petals, and four lines including 'Pe99-002⁷’were tolerance in natural disease.
Among them, twenty lines including ‘Pe99-017⁷’were above 60 cm of plant width, above 300 leaves in a plant. twenty nine lines including ‘Pe99-017⁷’ were more than 150 in the number of flower with the branch number ranged from 6.0 to 11.0 cm, and the internode length ranged from 2.0 to 4.2cm. In petal color, twentyeight lines including ‘Pe99-017⁷’were red-purple; five lines including ‘Pe99-007⁷’were purple; six lines including‘Pe04-086⁷⁷’were violet; and four lines including‘Pe072-1⁷’were white. Eleven lines including ‘Pe02-205-2⁵’ ranged from 4.0 to 5.0cm of flowers diameter, and ten lines including ‘Pe04-086⁷⁵’ ranged from 3.0 to 4.0cm of leaf length, which is relatively low. And the 10 F₁ crosses were also showing different growth and flowering characteristics. Germination rate of the selected lines was more than 50%.
Selection of 40 Pure Lines and 17 F₁ Crosses in Wave Petunia
In wave petunia, twenty seven lines ‘Pe99-017⁷’and 13 F₁ crosses including ‘F1-033’were middle flower petals, eight lines including ‘Pe04-091-1sup>5’and four crosses including 'F1-71’were small flower petals, and five lines including 'Pe04-017-4⁵’were tolerance in natural coldness.
Among them, twenty nine lines including ‘Pe99-020⁷’were above 60 cm of plant width, above 200 leaves in a plant. Twenty three lines including ‘Pe04-103-1⁷’were more than 150 in the number of flower with the branch number ranged from 6.0 to 11.0 cm, and the internode length ranged from 2.0 to 4.2cm. In petal color, twenty nine lines including ‘Pe99-020⁷’were red-purple; five lines including ‘Pe04-113-4⁵’were red; six lines including ‘Pe04-103-1⁵’were purple; two lines including‘Pe04-072-5⁵’were violet; and two lines including‘Pe04-180-2⁵’were white. And the 17 F₁ crosses were also showing different growth and flowering characteristics. Germination rate of the selected lines was more than 50%. All the lines of various growth and flowering characteristics would be very promising to use as breeding materials for F₁ hybrids of spreading petunia.
2. Practical Farming Test and Consumer Favorites of Breeding Cultivars
New breeding lines and crosses of surfinia and wave petunia from Korea National Agriculture and Fisheries College were grown in the same conditions to investigate the growth, flowering characteristics and consumer favorites. Most new breeding ones were no significant difference in the growth and flowering characteristics tocompared with some commercial varieties. Rather, some new ones has excellent growth and flowering characteristics for consumers. The preference of new breeding ones in surfinia, 'F1-049' and 'F1-036', in wave 'F1-034' and 'F1-046' with excellent flower color higher than that of commercial varieties. Therefore they are expected to cultivate and propagate for the farmer and consumer in the future.
Control of the Flowering Stage by Sowing Time and the Price Changes by Shipping Time
To investigate the flowering time of wave petunia, every month from January 10 to October 10 were sowing. Sowing on January 10 was flowered at the end of April duration of 110 days. Sowing on June to August was flowered 70 days to blooming. Sowing of April to June period were shortened days to flowering.
Petunia auction was late March to July and high quantity in May. The average price per 15 cm pot was trading from 800 to 2200 Won. Marketing prices of wave petunia starting from the end of March was highest and then the time passed, the prices also tended to decline.
Current Using Survey of Spreading Petunia
Spreading petunia has been using for railing of a bridge, the road ridge decoration, street lamp decorations, garden decoration, or hanging pots.
3. Consumer Favorite Test of Breeding Petunia by Cultivar Evaluation and Their Propagation
Breeding petunia Evaluation
This work was conducted to evaluate finally for breeding line and combinations of spreading petunia 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 Korea National Agriculture and Fisheries College on may 26, 2009. About 150 people attended the meeting consisted of spreading petunia farmer, nursery and seed businessman, and agricultural researcher and officer.
In the evaluation new spreading petunia at the Some new breeding lines and combinations were excellent compared to commercial cultivar, spreading growth and number of flower in characteristics. They were also excellent degree of consumerfavorite, and high price of survey. Therefore they are expected on cultivation and propagation in the future.
Propagation of Spreading Petunia
Free diffusion for six F₁ hybrid 2400 seed at two farmers after documentation process at the iPET(Korea Institute of Planing and Evaluation for Technology of Food, Agriculture, Forestry and Fisheries).
4. Final Selection for Variety Registration of Breeding Spreading Petunia.
Wave petunia was selected 9 variety among 47 combinations, surfinia petunia was selected 5 variety among 11 combinations. they will have named and registrate at the KOREA SEED & VARIETY SERVICE. The selected combinations were excellent in spreading growth and flowering characteristics compared to commercial cultivar. They had also excellent degree of producer favorite, therefore they are expected on cultivation and propagation in the future.
5. Seed Formation by Crossing Time and Methods of spreading petunia.
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 combinations of spreading petunia.
The normal pollination in the wave petunia 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 8 to 10 times of crossings. The ripening seed capsule and its seed number per capsule of selfing was very low compared to out crossings, specially in surfinia petunia. The out crossing had much more ripening seed capsule than that of selfing in the lines, above 82 percent and number of seed per capsule from 170 to 295.
The ripening seed capsule and number of seed in a capsule from March to October were most excellent during May, June, and September when the night temperature was 13 to 20℃, day temperature 20-28℃.
6. Correlation and Combining Ability of Plant Spreading Chracteristics in F₁ Hybrids by Diallel Cross in Petunia ☓ hybrida
The correlation and combining abilities related with plant spreading characteristics of plant height, plant width, stem length, internode length, number of stem, number of leaves, and number of flower were studied in the F₁s of 10 crosses from the partial five-parent diallel cross in Petunia ☓ hybrida.
The plant width showed highly positive correlation with internode length, and number of flower. The mean squares of general combining ability(GCA) and specific combining ability(SCA) were highly significant for plant width, number of stem, number of leaves, and number of flowers. The mean square values of GCA were greater than those of SCA for all the characters, showing preponderance of additive gene actions for these characters. The lines of D and I for plant width and length of stem showed relatively high GCA effects. The crosses of D×I, F×I, and G×I exhibited high SCA effects on plant width, especially G×I effected in internode length and number of flower. The broad sense heritability was generally high compared to narrow sense one. Plant width and stem length, and internode length related to spreading growth showed the higher heritability than the other characters in the broad and narrow sense.
