Genesis: Seed is the basic and most critical input in agriculture and is considered to be the cheapest and most crucial component compared to other inputs like fertilizers, pesticides, water etc. The need to popularize the concept and use of quality seed is warranted for high crop productivity. The existing machinery in the state for production of quality seed, processing, storage and distribution, needs to be geared up to on scientific footing. This realization paved way for the establishment of Seed Technology Unit at College of Agriculture, Vellanikkara during 2013. The Unit was later upgraded to the Department of Seed Science and Technology.  The activities in the Department have been conceived and coordinated to spur the growth of both seed industry and agriculture production in the state of Kerala.

Vision / Objectives:  

·        To undertake UG and PG courses in Seed Science and Technology as envisaged by ICAR, to further strengthen and provide impetus to teaching, research and extension activities in seed technology

·        To undertake basic and applied research related to seed production and technology through multi-disciplinary approach

·        To undertake HRD/training programmes related to Seed Science and Technology to officials of Department of Agriculture Development and Farmers Welfare, registered seed growers etc.

·        To encourage seed production and post-production technologies to meet the need of the State

Mandate:

Teaching, research and extension in seed production and certification, processing, storage and testing of field crops, fruits, vegetables, plantation crops, spices, flowers, aromatic and medicinal plants

Facilities:

·        Seed complex housing the under-graduate and Post-graduate classrooms, library, germination room and laboratories

Achievements / Major Accomplishments :

a) Education:

·        Establishment of Department of Seed Science and Technology with instructional, laboratory and field research facilities at the College of Agriculture, Vellanikkara [Proc. No. Acad/B2/39139/2011 dated 17/01/2013 of Director (Academic)]

·        Twenty Two students have successfully completed their post-graduate programme. (Intake of students for MSc per batch- four from 2013 onwards)

b) Research:

·        Collection and insitu conservation, characterization and purification of traditional rice varieties of Kerala and their large-scale multiplication of has been taken up under Farmers participatory seed production mode.

·        Exploration and collection of traditional varieties of rice, op melon, ash gourd, pumpkin, bitter gourd, snap melon and tuber crops from various parts of the state have been done.

·        Iron toxicity tolerance of rice accessions can be delineated when toxicity level reaches 600ppm. Out of the 154 short duration rice accessions held by KAU, PGC 36 [Cul 8723 (IC 253584)] was found to exhibit tolerance at a higher toxicity level of 800ppm iron.

·        Backcross pyramids with three BB resistant genes xa5, xa13 and Xa21 have been developed in the background of two indica rice varieties Jyothy and Uma.

·        Paddy seeds packed in polyethylene bags 400G recorded superior seed quality parameters compared to seeds packed in jute bags.

·        Halogenation of paddy seeds with calcium oxychloride through carrier calcium carbonate @ 3g/kg seed each, recorded superior seed quality parameters throughout storage compared to untreated seeds.

·        Storing of paddy seeds in polyethylene bags 400G after treatment with CaOCl₂+CaCO₃ @ 3g/kg seed helped retain germination above MSCS for the longest period of storage (fourteen and ten months during rabi and summer 2013-14 respectively), indicating its superiority in prolonging seed longevity.

·        The viability retention among cowpea varieties varied with the genotypes

·        Bush types cowpea varieties (Sreya, Hridya and Bhagyalakshmi) registered a lower germination per cent compared to semi-trailing and trailing types.

·        The semi-trailing varieties (Anaswara, Kairali, Kanakamony and Kashi Kanchan) recorded the highest germination after ten months of storage followed by trailing type (Lola, Vellayani Jyothika and Vyjayanthi).

·        The varieties Kashi Kanchan and Kanakamony maintained germination per cent above minimum seed certification standards upto six months of storage.

·        Bold seeded varieties like Vellayani Jyothika, Anaswara, Lola and Vyjayanthi exhibited a lower germination compared to other small seeded varieties.

·        Poor germination in seeds of ash gourd may be due to a water impermeable seed coat (physical dormancy) mainly owing to thickening of outer layer the testa. This can be overcome by invigoration treatment.

·        Pre-sowing seed invigoration in ash gourd with 50 mM CaCl₂ for 12 hours or 24 hours, or Pf for 12 hours, or kinetin 10 ppm for 24 hours helps break seed dormancy in ash gourd.

·        Seed treatment with CaCl₂ 50 mM   for 24 hours in ashgourd helps retain the viability for the maximum period (7 months after extraction) compared to untreated seeds (2 months after extraction) under ambient storage.

·        Seed treatment with seed protectants viz., spinosad or neem based products (neem kernel powder, neem leaf powder and neem oil) or as oils (coconut oil and castor oil) were most effective in enhancing seed viability (by a period of one month over control), higher seed and seedling performance and proving protection from pulse beetle infestation and infection by microflora in cowpea.

·        Halogenation of  chilli seeds with CaOCl₂ + CaCO₃ @ 2g each per kg of seeds or  iodine crystal + CaCO₃ @100 mg each per kg of seeds or iodine crystal + CaCO₃ @50mg per kg of seeds or  CaOCl₂ + CaCO₃ @ 4g per kg of seeds were found to be effective in prolonging the viability under ambient storage.

·        Seed treatment in chillies using nano-size botanical enhanced seed quality and seed longevity when compared with the commercial grade botanicals.

·        Seed treatment with commercial grade botanicals, arappu @ 2g/kg, fenugreek @ 2g/kg, and fenugreek @ 0.5g/kg, were found to improve the storability of chilli seeds and to increase seedling vigour in the field.

·        Treatment of chilli seeds with nano size botanicals, viz., custard apple @ 0.5g/kg, fenugreek @ 1g/kg, and fenugreek @ 0.5g/kg, were found  to enhance the storability and seedling vigour.

·        Seed invigoration in chilli with nZnO @500 mg/kgand nTiO2 @500mg/kg were effective in enhancing seed viability.

·        Treatment of Abscisic acid (300mg/l ABA) was effective in reducing vivipary upto 1.37 per cent and maintaining seed quality in oriental pickling melon.

·        Seed biopriming with the combination of Pseudomonas fluorescens @ 10g/kg, Trichoderma viride @ 4g/kg and coconut water @ 75% increases the seed quality and seed longevity in rice.

c) Seed production:

·        Since inception a total of 3770.16 tonnes of paddy seed has been produced and distributed from this centre as on 31^st Dec 2021. On an average 147 tonnes of truthfully labelled seeds of paddy are being produced and supplied from the centre every year. Apart from paddy, quality seeds of oilseeds (Sesame), green manure crops (Daincha), vegetables (Cowpea, Bhendi etc) are also being produced at the centre to cater to the need of farmers as well as distribution through Department of Agriculture Development and Farmers Welfare, Kerala.
