2004 Cereals reveal an intriguing surprise: the performance of cereals on organic farms Organic Eprints
Wolfe, Martin; Hinchsliffe, Kay.
The great variability in the performance of cereals on organic farms that we have highlighted from past research trials has been confirmed in a new and more widely based trial. Participation from 20 producers gives the results a robust character and has enabled us to spot something we had not previously noted. EFRC researchers Prof Martin Wolfe AND Kay Hinchsliffe set out the results. Introduction EFRC is currently working on a Defra-funded project designed to use participatory research and development methodology, and is conducted on sites across the country with the participation of 20 farmers, seed producers and more than 10 researchers (EFRC, NIAB, Middlesex University, University of Kingston & HDRA). The idea is to integrate the contributions...

A Collaborative Breeding Strategy for Organic Potatoes in the Netherlands Organic Eprints
Lammerts van Bueren, E.T..
The ability of the organic farmer’s agronomic toolbox to reduce the susceptibility of a potato crop to late blight is limited, certainly under the Dutch climatic conditions. Conventional breeding programs do not generate either a sufficient number nor appropriate types of resistant varieties for organic systems; and a separate breeding program for the limited area of organic potato production is simply not viable. Therefore, all concerned forces have joined together in an umbrella program called Bioimpuls for organic potato improvement.

A major gene for grain cadmium accumulation in oat (Avena sativa L.) Organic Eprints
Tanhuanpää, Pirjo; Kalendar, Ruslan; Schulman, Alan; Kiviharju, Elina.
Four DNA markers associated with Cd concentration were found: two RAPDs (random amplified polymorphic DNAs), one REMAP (retrotransposon-microsatellite amplified polymorphism), and one SRAP (sequence-related amplified polymorphism). The markers were assigned to one linkage group which exhibited a QTL (quantitative trait locus) representing a major gene for Cd accumulation. The markers can be used in future breeding programmes for healthy oat cultivars.

A Treasure of Crop Diversity from Outstanding Farmer-Breeder, JP Singh (India) Organic Eprints
Singh, Jai Prakash; Mansata, Bharat; Nellithanam, Jacob; Kundaji, Deepika.
Jaiprakash Singh (aka JP) is an outstanding organic farmer breeder of several important and widely cultivated crops like rice, wheat, pigeon pea and mustard. He started this work more than 2 decades ago, and presently has 480 varieties of rice, 120 varieties of wheat, 40 varieties of pigeon pea, 3 varieties of mustard; also some chillies and tomatoes. These varieties are ‘developed’ or evolved over many crop cycles through a process of multi-generational selection for distinct features and qualities, including grain yield, pest resistance, special nutritive values, flavour, fragrance, grain size, shape, colour, etc. The varieties bred by JP are particularly useful for many farmers still following or reverting to indigenous organic system in India. JP’s 5...

A user-friendly database for Participatory Plant Breeding programs Organic Eprints
Rosenfeld, Simon; Parzies, Heiko; Grando, Stefania; Ceccarelli, Salvatore.
In a decentralized and participatory plant breeding (PPB) program, in contrast to conventional plant breeding, farmers select from a large number of genotypes over a number of cycles in several locations. As selection is for location-specific adaptation a PPB program based on, for example, four stages of selection, generates large, unbalanced data sets. With common spreadsheet software it is not possible, or it is at least very cumbersome to extract all the information, particularly the one that is related to genotype x environment (GE) interactions. Therefore, there is a need for an information system that makes it as easy as possible to retrieve and compare data over all given factors in the PPB-program. Due to a lack of education and financial resources...

A weed suppressive index for spring barley (Hordeum vulgare L.) varieties Organic Eprints
Hansen, Preben Klarskov; Willas, Jakob; Kristensen, Kristian.
A screening programme for crop variety competitiveness would ideally be based on only a few, non-destructive measurements of key growth traits. In this study we measured the weed suppressive ability of 79 varieties of spring barley in two ways: 1) directly, by weed coverage assessments under weedy conditions at three Danish locations in 2002-2004, and 2) indirectly, by non-destructive measurements of varietal growth traits under weed-free conditions in 17 other experiments in Denmark in 2001-2003. Based on just four varietal growth traits (reflectance, leaf area index, leaf angle and culm length), we successfully developed a method for indexing the weed suppressive ability of spring barley varieties. The suppressive index ranged from 12% in ‘Lux’ and 55%...

Acknowledging the Role of Gender in Organic farming, Informal Seed Sector in particular and krisoks’ Perspectives Organic Eprints
Shahid, Shaila; Md. Hossain, Zakir.
Seed-the source of life. And woman holds the seed with the hope of new life. Instead of producing diverse seed from homestead agriculture, women are engaged traditionally to select seed, drying, preserving, protecting during storage, saving them from any economical crisis of the family. To ensure the seed quality and the perfect storage place & methods, women hold the vast knowledge. They decide the quantity and variety of seed to be saved and the method of preservation. Seed selection by women is a continuous activity. Working in the fields, they observe the plants and decide which seeds to select. They identify plants of good quality on the basis of size, grain formation and their resistance to pests and insects. Here a woman looks at the seed...

Adaptation of lupins for Northern European maritime conditions Organic Eprints
Joernsgaard, B.; Christiansen, J.L.; Kuptsov, N..
Lupin as a grain crop has been restricted in growing area to more continental conditions due to their indeterminate growth form, which in maritime Northern European areas causes excessive vegetative development, late and uneven ripening and lodging. However, new reduced branching types provides better possibilities for adaptation to these conditions, and preliminary results indicates potential seed yields up to 5-6 tons per ha in the narrowed leafed lupins (Lupinus angustifolius) and an acceptable stable and early ripening. Due to full susceptibility to anthracnose (Colletotrichum gloeosporioides) in white (L. albus) and yellow (L. luteus) their introduction in these environments is doubtful. In these growing areas Botrytis (Botrytis cinerea) and fusarium...

Against the grain Organic Eprints
Döring, Thomas F.; Crowley, Oliver; Wolfe, Martin.
An Organic Research Centre project is examining how diversity-based tools can assist in the on-farm improvement of organic wheat. Successful organic crop production requires varieties that are resistant to diseases, competitive against weeds, and effective at scavenging nutrients. Yet conventional plant breeding has largely neglected organic systems by breeding varieties exclusively for high input conditions. As a consequence, organic producers currently do not have enough choice of plant varieties for organic conditions. One way to expand the choice is to create plant diversity anew and subject it to natural selection on organic farms. After several generations the dominating plants would be better suited to organic systems. This idea is being tested...

Agronomic characteristics of the spring forms of the wheat landraces (einkorn, emmer, spelt, intermediate bread wheat) grown in organic farming Organic Eprints
Konvalina, Petr; Capouchova, Ivana; Stehno, Zdenek; Moudry, Jan.
Organic farmers look to the possibilities of growing neglected crops, such as the spring forms of hulled wheat – einkorn, emmer and spelt – for support in developing the organic farming system. In 2008, 169 landraces from the gene bank at the Crop Research Institute in Prague were tested on certifi ed organic plots. The experiment was aimed at fi nding suitable varieties for the organic farming system. In summary, our fi ndings show that einkorn (Triticum monococcum L.) and emmer wheat [Triticum dicoccum Schrank (Schuebl)] are resistant to powdery mildew and brown rust, spelt wheat (Triticum spelta L.) is less resistant to these two diseases, and the intermediate forms of bread wheat are very sensitive to such infestation. The varieties evaluated incline...

Agronomic performance of two generations (F12 and F13) of thirteen winter wheat composite cross wheat populations with differing cultivation histories in 2014/15. Organic Eprints
Weedon, Odette; Brumlop, Sarah; Heinrich, Sven; Boening, Andreas; Elsner, Maren; Finckh, Maria R.; Lammerts van Bueren, E.T.; Nuijten, E.; Messmer, Monika; Baresel, Jörg Peter; Goldringer, I.; Péter, Mikó; Megyeri, Maria; Borgen, Anders; Rasmussen, Søren K.; Pearce, Bruce; Wolfe, Martin.
As environmental and agronomic conditions are heterogeneous between and within locations, diversity within varieties or crop populations should increase adaptability to the changing and variable range of growing environments. The additional pressure of plant genetic diversity loss, has driven novel breeding approaches such as Composite Cross Populations (CCPs) and other genotype mixtures, thereby increasing both intra- and inter-varietal diversity and ensuring a “wider adaptation” capacity for crop varieties (Döring et al., 2011). A winter wheat (Triticum aestivum L.) CCP was created by intercrossing 20 varieties in 2001, through collaboration with the Elm Farm Research Centre and the John Innes Institute. In 2005, a seed batch of the F4 was equally...
