Wheat seed production technique India

Wheat seed production with cultivation method

seed production technique in wheat
Certified ( C) and Foundation (F) wheat seed production (Triticum spp)
Wheat is a one of the important cereal crop and India is the second largest producer of wheat in the world after china. In modern Agriculture in exploiting the full potential of a variety. The wheat seed production that reaches to the farmers should have given high genetic purity as well as high physical, physiological and health quality. In Indian farmers select and save the seed next year sowing so therefore the seed supplied to the farmers should be best quality wheat seed production. Therefore best practice to produce quality seed should be followed –
1.     .1  Land 
            For seed production the land shall be free of volunteer plants. The field should be well-drained, free of weeds and soil neither be too acidic nor too alkaline. Contamination of “ Kernal bunt” disease can be reduced by increasing intervals between crops.
2.     2.  I.D.
        In wheat the extent of cross-pollination varies from 1 to 4% Normally I.D. is 3 meters and all round wheat field a non-cereal crop is planted. In case of variety susceptible to Ustilago spp., the I.D. is 150 meters, where loose smut infection is in excess of 0.1% F.S. production and 0.5% in C.S. production. This distance is maintained for fields with infection of loose-smut in wheat, Triticale and Rye also.

3.   3    A.  Field Standards
i)                    Minimum number of inspection and stages : 2 from flowering to harvest.
ii)                   Maximum off types (%) permitted : 0.05 and 0.20(ear heads) for F.S.  and C.S. respectively.
B. Specific requirements
   i) Standards for offtypes and inseparable other crops shall be met at the final inspection and for loose smut shall be met at any inspection conducted between ear emergence and harvesting.
ii) Inseparable other crops shall be : barley, oats, triticale and gram.
iii)                 Seed brone disease shall be : loose smut (Ustilago tritici Jens.)
4.    4.   Seed standards
  • ·         Pure seed (minimum) Foundation  – 98.0%, Certified- 98.0%
  • ·         Inert matter(maximum) F- 2.0% , C- 2.0%
  • ·         Other crop seeds (maximum) F- 10/kg, C – 20/kg.
  • ·         Total weed seeds (maximum ) F- 10/kg, C-20/kg
  • ·         Objectionable weed seeds (maximum) F-2/kg, 5/kg.
  • ·         Seeds infested with Nematode gall of Ear-cockle    None
  • ·         Seeds infected by karnal bunt (Neovossia indica) F-0.050%, C-0.250%
  • ·         Germination (minimum) F- 85%, C-85%
  • ·         Moisture(maximum) F-12.0%, C-12.0%
  • ·         For vapor proof-containers(maximum) F- 8.0%, C-8.%
  • Objectionable weeds shall be: wild morning glory (Hirankhuri) (Convolulus arvenis L.) and Gulli danda (Phalaris minor Retz.)
5.     5Harvest, cleaning and bagging
      Combine only when moisture content below 16%, start combining from later morning hours. Wheat seed is very dry at harvest. Before monsoons the seeds should be stored in a dry, insect and rodent free godown.
6.    6.   Seed yield
Average 30 to 40 quintals per ha. wheat seed production.
