Production - Technology
Some of important technical aspects of hybrid seed production of important field crops are as below
| Crop | Fs requirement/Ac | Female/Male | Isolation distance (mts) | Pollination Method | Remarks | |
|---|---|---|---|---|---|---|
| Female (Kg) | Male (Kg) | |||||
| Bajra | 1.5 | 0.5 | 6:2 | 400 | Wind pollination | Depending upon the plant height and pollen shedding capability of pollen parent, row ratio can be increased/decreased |
| Paddy | 6.0 | 3.0 | 6:2 | 100 | Shaking of male rows with sticks to ensure pollen dusting | Spraying of chemicals like GA3 and leaf clipping helps in better exertion and seed set |
| Sunflower | 1.5 | 0.5 | Separate blocks in 3:1 ratio | 400 | Pollen is collected from male plants & gently rubbed on females | Pollen can be stored in refrigerators for 2-4 days in case of delay in flowering of female rows |
| Maize | 5.0 | 2.5 | 4:1 or 6:2 | 400 | Wind pollination | De-tasselling of female rows is done manually before they start shedding pollen |
| Sorghum | 3.0 | 1.5 | 8:2 | 250 | Wind pollination | Avoid Cool and rainy days during flowering |
