Evaluation and selection of true potato (Solanum tuberosum) seed families in North-Central plains of India

Segregating progenies from 19 crosses of potato (Solanum tuberosumL.) developed at the International Potato Center (CIP), Peru were tested during 2008-2013 for adaptation and yield attributes in the sub-tropical plains of India i.e. Modipuram, Uttar Pradesh. The progenitors of the crosses showed early foliage maturity, tolerance to biotic stresses and processing attributes. In initial clonal generations, selection was based on desirable tuber attributes and tuber yield components. Clones showing viral symptoms, producing long stolons, irregular tuber shape, russetting, cracking or deep eyes were eliminated. From the initial population of 17,300 true seeds, 13 advanced clones of five crosses were subjected to evaluation in replicated trials and nine better performing clones were selected. Critical evaluation of these nine clones resulted in the identification of five promising clones (305069.701, 305111.701, 305138.702, 397186.703 and 397186.704) with high tuber yield (43 to 50 t/ha) and desirable tuber attributes. These advanced clones hold promise of becoming new potato cultivars and may be used in breeding programmes aiming at high productivity in the region for improving the livelihood of farmers.

Effectiveness of Protection of Early Potato Cultivars Against Phytophthora infestans Mont De Bary depending on the Protection Strategy
December 18 2017 by INKOA

The research was based on the field experiments conducted in 2014–2016 in the Variety Assessment Experimental Station, Central Center for Cultivar Assessment in Uhnin on the fawn soil, with a slightly acidic reaction, on rye good complex. The experiments were set up as random blocks in a dependent arrangement in three replications. The strategy of potato protection against late blight was the factor of a first line (from three to nine fungicide applications and a control object – without protection). Potato cultivars (5) with different level of resistance on Phytophthora infestans were the second experimental factor. 

Integrated farming system for sustainable hill agriculture: an option for Climate Smart Agriculture and natural resources management
November 9 2017 by INKOA

Sustainable development on our planet cannot be achieved without a major contribution from agriculture. People must be fed, and agriculture has to face the challenge of producing sufficient food for a rapidly growing world population whilst maintaining the world’s fragile resources. Modern farming systems have evolved to meet this need in a way that combines the essential requirements of profitability and productivity. Sustainable development must encompass food production alongside conservation of finite resources and protection of the natural environment so that the needs of people living today can be met without compromising the ability of future generations to meet their own needs. Economic and ecological access to food could be only ensured by adopting farming system approach consisting of change from commodity-based to resource-based planning and integrated use and management of land, water and human resources to maximize income and employment. The primary goals of farming system is to maximize the yield of all component to provide study and stable income at higher level, rejuvenation of systems productivity and achieve agro-ecological equilibrium. Biotech stress management through natural cropping systems management and reducing the use of fertilizers and other harmful agrochemicals to provide pollution free, healthy produce and environment to the society. The Training Manual on "Integrated Farming System for Sustainable Hill Agriculture : An Option for Climate Smart Agriculture and Natural Resource Management" deals with various aspects of integrated farming system in a holistic way.

Potential of golden potatoes to improve vitamin A and vitamin E status in developing countries
November 9 2017 by INKOA

Potato (Solanum tuberosum L.) is the third most widely consumed plant food by humans. Its tubers are rich in starch and vitamin C, but have low or null levels of essential nutrients such as provitamin A and vitamin E. Transformation of potato with a bacterial mini-pathway for β-carotene in a tuber-specific manner results in a “golden” potato (GP) tuber phenotype resulting from accumulation of provitamin A carotenoids (α- and β-carotene) and xanthophylls. Here, it is investigated the bioaccessibility of carotenoids and vitamin E as α-tocopherol (αTC) in boiled wild type and golden tubers using in vitro digestion.

Cooperation Across Continents: Success stories from the ERAfrica Partnership
November 2 2017 by INKOA

The ERAfrica project, funded by the European Union’s Seventh Framework Programme, was the first to bring together research funders from Africa and Europe to jointly design and launch instruments, regulations, and procedures for funding collaborative, bi-regional research projects. With a total of 8.29 million euros granted, ERAfrica funded 17 bi-regional projects with 65 institutions (31 Africa, 34 European) from 18 countries (8 African, 10 European).

RINEA has published a booklet highlighting the projects funded from ERAfrica. Although not all of the projects have finished their work, each has been conducted in the spirit of the EU-Africa partnership in science, technology, and innovation and shows the commitment of African and European countries to contribute to finding solutions to challenges that affect both regions.

Biosorption of heavy metals: a case study using potato peel waste
October 17 2017 by INKOA

Potato peel waste (PPW) from food processing was used for removing As3+, Pb2+, and Hg2+ heavy metals from water. The response surface methodology (RSM) and the central composite design (CCD) were employed for determining optimal conditions for heavy metal removal. The statistical analysis indicates that the effect of pH is the most significant parameter. The optimal condition for achieving the maximum removal was obtained for removing different metals using RSM. Desorption study indicates its good reusability within three recycling steps.
