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 distances(Meters) | Pollination Method | Remarks | |
| Female (Kg) | Male (Kg) | |||||
| Bajra | 1.5 | 0.5 | 6:02 | 400 | Wind pollination | Depending upon the plant height and pollen shedding capability of pollen parent, row ratio can be increased / decreased. |
| Paddy | 6 | 3 | 6:02 | 100 | Shaking of male rows with sticks to ensure pollen dusting | Spraying of chemicals take 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 if delay in flowering of female rows. |
| Maize | 5 | 2.5 | 4:1 or 6:2 | 400 | Wind Pollination | De-tasselling of female rows done manually before they start shedding pollen. |
| Sorghum | 3 | 1.5 | 8:02 | 250 | Wind Pollination | Avoid Cool and rainy days during flowering. |
| Cotton | 0.5 | 0.25 | 2:1 | 50 | Hand Pollination | Emasculation of Female done a day before and then next day pollinated with male flowers. |
| Mustard | 1 | 0.20 | 4:1 or 4:2 | 200 | Wind Pollination | In case of Hybrid wind pollination and in case of CMS lines, no emasculation is required. |
