Tomato is a very important vegetable in the Solanaceae family. This highly nutritious vegetable is grown almost all over the world. Hybrid tomatoes are very popular due to high yield, early harvest, off-season production, etc. Most of the seeds produced by the world's leading seed companies are hybrid seeds. Producing good seeds for any crop as a whole is more efficient and laborious than producing the same crop. And in the case of hybrid seed production, more attention, special knowledge and skills have to be applied in conducting the entire activities.
The following is a brief overview on hybrid seed production techniques.
Hybrid breeds
A hybrid variety is a variety that is produced by hybridization between two rows of mother and father plants with different characteristics and whose productivity is higher than that of both mother and father plants.
Different stages of hybrid tomato seed production
Hybrid tomato seed production is not like normal crop seed production. This is done with special care in the following steps.

  1. Parental line development / inbreeding / breed selection
  2. Production, planting and care of seedlings
  3. Female flower selection and sterilization
  4. Pollen collection
  5. Pollination and subsequent care
    . Maternal and father row management
    . Inter-care
    . Seed fruit collection
  6. Seed collection.
  7. Parental line development / inbreeding / breed selection
    Quality seeds should be collected by selecting the desired parent / variety. It should be noted that the established method in the production of any hybrid seed is the development of pure maternal and paternal lineage through various processes. Hybrid seeds are then produced by transferring pollen from the parent plant to the mother flower. Therefore, it is necessary to collect the seeds of pure mother-father tree of the desired hybrid variety. Note that the mother tree is called "seed mother" and the parent tree is also called "pollen mother".
    Depending on the variety, the life span of tomato is 120-150 days. Seed sowing time is September-October. Seed 200 gm per hectare (1 g / per cent). However, in the case of hybrid seed production, 160 g of seed female and 30 g of seed male flower are required.
  8. Seedling production Planting and care
    In order to produce vigorous seedlings, first 50 g of healthy seeds have to be sown in each seedbed (1 md 3 m).
    As per this, 4 seedbeds are required for sowing 200 gm (1 gm / per cent) seed per hectare (germination rate 80%). But in hybrid seed production, 30 g of seed has to be sown 8-10 days before sowing of female seed for male flower production.
    8-10 days after germination of seedlings in the second seedbed 4 x 4 cm. Need to move distance.
    To cultivate tomatoes in one hectare of land requires 22 such seedbeds.
    Covering the seedlings with 40-60 mes (40-60 holes per inch) covered with nylon net can provide relief from the spread of leaf curl virus by whitefly insects while in seedling stage. Good yields are obtained by planting such healthy strong and virus free seedlings.
    Polythene and mat cover should be used to protect from excessive rain and sun.
    Land ready
    Good yield of tomato seeds largely depends on land preparation. So you have to cultivate the soil 4-5 times with a ladder. 1 m depending on the nature and location of the soil. Wide and 15-20 cm. High beds need to be made. 30 cm between the two beds. Wide drains should be made to facilitate irrigation and drainage.
    Fertilizer application: Fertilizer application is required at the following levels.
    The last dose of dung and chemical fertilizer should be mixed well with the soil before final cultivation. Top application of urea and MOP fertilizer at the base of the plant 10-15 cm. It should be mixed well with the soil at a distance.
