Achievements

Crop improvement

 

  • Genetic resources management
  • Two thousand nine hundred and fifteen (2915) germplasm accessions were being maintained at PC & GMU, Kanpur were characterized for 8 quantitative and 12 qualitative traits for developing core collection.
  • Two thousand six hundred eighty six (2686) accessions were conserved in National Gene Bank, New Delhi for long-term storage.
  • Three germplasm accessions (IC 564627, IC 564681 and IC 563952) were registered by PGRC, NBPGR, New Delhi.
  • Four breeding lines were identified with low linolenic acid content (less than 4%).
  • EC 541221 was identified for high linolenic acid content (66%).
  • Molecular characterization of 10 linseed varieties using RAPD marker was done at PC Unit, Kanpur.
  • DNA finger printing of 26 varieties using SSR markers was done at NBPGR, New Delhi.
  • Application for five linseed varieties , Padmini, Parvati, Sharda, Binwa and Baner was submitted for protection under PPV&FR Act., 2001.
  • Catalogue (3rdedition) comprising 268 local land races for 25 descriptors was published in 2010.
  • A compendium on linseed varieties as per DUS characteristic was published in 2011.
  • Potential donors of indigenous and exotic accessions have been identified for different target traits of interest, which are being used for crop improvement.
  • Innovative research  (supported by flexi budget)
    • Bacillus subtilis, an isolated bacterium was identified for microbial retting of flax. Him Alsi-2 gave maximum retted straw yield along with best fibre softness and fineness. Retting duration was also significantly reduced on bio-inoculation.
    • Ethidium bromide (0.1%) was found more effective in inducing pollen sterility in comparison to gamma rays.
    • Genetic diversity of 70 linseed genotypes was assessed with the use of ISSR markers and genotypes were grouped into 18 clusters. Phenotyping of 4 RILs was developed for fibre quality traits.
    • Under Pre-breeding programme two inter-specific crosses were attempted and evaluation of segregating generations is going on in order to select resistant genotypes against Alternariablight and linseed bud fly.
    • Identification of heat tolerant genotypes and their physiological characterization.

   Crop production

  • Clodinafop @ 80 g/ha was found quite effective to manage the weeds where ever Isoproturon @ 1 kg/ha is not effective.
  • Bacillus subtilisbacteria identified best source for microbial retting of flax for fibre softness and fineness.
  • Developed location and situation specific integrated nutrient management modules;
  • Intercropping of linseed ‘Garima’ with autumnplanted sugarcane in 1:3 row ratio e., sugarcane+linseed (1:3), proved very promising in sugarcane production system for getting higher net returns.
  • Application of ZnSO4@ 25 kg/ha in kharifalong with FYM@ 5 t/ha proved effective in enhancing net returns in double cropping system like paddy-linseed, maize-linseed, soybean-linseed, black gram-linseed etc.
  • linseed crop can be sown successfully in double cropping system up to second week of November (Himachal Pradesh) last week of November (Uttar Pradesh & Tawa command area of Madhya Pradesh) 1stweek of November (Jharkhand), last week of October (Maharashtra & Madhya Pradesh).
  • Nagarkot, Himani and Baner in maize-linseed crop system in Himachal Pradesh, Garima, Shubhra, Shekhar and T 397 in black gram-linseed crop system in central Uttar Pradesh Garima in rice-linseed crop system in eastern Uttar Pradesh Kartika and JLS 59 in soybean-linseed crop system of Madhya Pradesh were observed as promising varieties of linseed.
  • Soil moisture conservation with hand weeding in clayey soil of Nagpur, soil mulching at 30 DAS in Parwa soil of Bundelkhand of Uttar Pradesh and straw mulching @ 10 t/ha in Vertisols soils of Madhya Pradesh and Chhattisgarh were quite effective under rainfed conditions. Intercropping of linseed with seed drill sown wheat in 2:2/4:4 row ratio in Uttar Pradesh and in 4:4 row ratio in Himachal Pradesh were observed promising than sole cropping of wheat; whereas gram + linseed intercropping in general but 6:4 row ratio at Nagpur and 4:4 raw ratio at Chhattisgarh were found to increased net returns over sole crop of gram and linseed.

Crop protection

  • Resistant varieties against wilt, rust and powdery mildew have already been developed.
  • Resistant donors against Alternariablight e.,  A-202, BAU-610A, Polf-29, GRF-1, RL-28003, T-397, EC-41590, Polf-17, ES-44, Ayogi, H-34, Polf-19, Polf-22 and linseed bud fly i.e., A-95 B, EC-1392, EC-1424, GS-234, IC-15888, JRF-5, LCK-88062, LMS-109-2K and Neela were identified.
  • Seed treatment with Thiram (3g/kg), Trichoderma harzianum (4 g/kg) / viride (4 g/kg) or Thiram + T.viride/ T. harzianum (1:1) reduced wilt incidence significantly.
  • 2-3 sprays of mancozeb (0.25%) / Iprodione (0.2%) / Companion 75 WP (0.2%), reduced severity of Alternariablight and enhanced seed yield.
  • Seed treatment with Topsin M (2 g/kg) and two sprays of aqueous neem leaf extract (5.0%)/ garlic bulb extract (5.0%) were effective in reducing Alternariablight infection.
  • Rust was effectively controlled, with spray of Mancozeb (0.25%) or Trizole compounds viz., Propiconazole (0.1%), Hexaconazole (0.1%) and Difenconazole (0.05%).
  • Developed IDM modules; including tolerant variety, seed treatment (2.0 g/kg Topsin M 75 WP), sowing during first week of November with recommended fertilizer doses and one spray of mancozeb (0.25%) on disease appearance.
  • Ladybird beetle (Coccinellids), the bio-agent under natural field condition, predate upon the maggots of bud fly.
  • Sowing of linseed with recommended agronomic practices and application of imidacloprid 200 SL (100 ml/ha) followed by tobacco leaf extract (0.5%) reduce bud fly infestation with maximum economic returns.
