Pineapple hybridization
Steps:- 1. Cross pollination
- Followers opening at 9-10 AM
- Not necessary to emasculate,Not necessary to isolate the plants or flowers
- Anthers collected to small box by forceps at around 10 AM
- Single anther rubbed over the stigma with forceps
- Pollinated flowers are net covered
- Crossed fruits should be labeled
- Ripen fruits are separately harvest for seed extraction
- Cut the ripen fruits & get the hybrid seeds
- Clean the seeds with water
- Seeds germination (4-6 weeks) - Seeds will be placed on bricks
- Keep on a water bath
- Half of the bricks should be get wet
- It has to be covered with polyethylene orpiece of flat glass
- 30-45 days old seedlings will be planted in the seedling trays & kept for 6 months
- Seedlings will be replanted in the field nursery & kept for 6 months
- Total period for nursery is about 1 year
- Lines should be evaluated by using fruit to row planting system
- Spacing 1x2 m (All the seedlings of one fruit should plant in one row)
- Plants should be selected forGene-typically differences,Characters for high yields & qualities
- Selected plants should be propagated by vegetative suckers
- Progeny screening & data collection should be continued up to third generation
Different locations (NCVT trials)
- Single row system should be adapted (spacing 0.30 x 1.00 m)
- Compare with recommended varieties
- Growth, yields & quality characters
- Data should be collected from the ratoon crops
