| 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. |

| 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... |

| Low-input production schemes adopted in organic or conventional farms require crop varieties that combine good product quality and high yield stability under non optimal environmental conditions (Gooding et al., 1999). These traits are not yet found among the durum wheat genotypes available in France. Consequently the cultivation of this crop is hardly successful in stockless organic farms in southern France, which are characterised by very low nitrogen resources. Some hopes emerged with the identification of new durum wheat pure lines with a high grain protein content in breeding experiments conducted near Montpellier in 2001 and 2002. The aim of the present work was to confirm and elucidate the origin of the enhanced protein performance of these new... |

| 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... |

| ABSTRACT Pepper is one of the main vegetable crops commercialized in Brazil and it is grown throughout the country. The objective of this study was to estimate genetic parameters and predict the genotypic values involved in agronomic traits of hybrid pepper in two different cropping systems in order to verify adaptability and genotypic stability. The experiment was carried out at the Experimental Station Luiz Jorge da Gama Wanderley from IPA, located in Vitoria de Santo Antão, Pernambuco State, Brazil, from October 2010 to March 2011. Seven hybrids were evaluated in two trials, the first in conventional farming system and the second in organic cultivation system. Randomized blocks were used with seven treatments, four replications and plots consisting of... |

| 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... |

| ABSTRACT: The objective of this study was to evaluate the plant and fruit characteristics in advanced lines of Jalapeño pepper for mechanical harvesting. Thus, two experiments were carried out in the field. Experiment I (2015) was conducted as a randomized block design (three replications and eight plants per plot) and Experiment II (2016) in a completely randomized design (five replications and ten plants per plot). In 2015, lines CNPH 30,112, CNPH 30,118, CNPH 30,147, CNPH 30,159, CNPH 30,183, and CNPH 30,245 were evaluated, together with the control ‘BRS Sarakura’. Significant differences were detected for fruit and plant characteristics (P<0.05). Lines CNPH 30,118, CNPH 30,147, CNPH 30,159, and CNPH 30,245 were selected based on plant height and... |

| 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... |

| ABSTRACT: Sweet cassava breeding programs are focused on the development of bio fortified cultivars that combine significant amounts of carotenoids in their reserve roots with desirable agronomic. The objective of this research was to evaluate agronomic and biochemical traits in sweet cassava clones with roots that have pink pulp. The nine genotypes were evaluated in two seasons in a randomized block design with three replications. Among the evaluated clones, the following stood out: i) for the height of the first branch (390/08, 345/08 and the control IAC 576-70); ii) for plant height (390/08, 345/08 e 378/08); iii) for shoot weight without original steam cutting (390/08, 406/08, 378/08 e 341/08); iv) for the percentage of starch in roots (378/08,... |

| Self-reseeding legumes are an essential component of the Mediterranean natural resources. Germplasms collected from the Mediterranean region were introduced in Australia and subjected to an extensive breeding. Species were then re-introduced in their original habitat where they were object of different important researches. Despite all the efforts made to select appropriate species and varieties, well-adapted cultivars have not been yet identified for all situations. At the experimental farm of the Mediterranean Agronomic Institute of Bari, Italy, agronomic performances of 15 cultivars of self reseeding legumes were compared on an alkaline soil to evaluate their possible use in organic agriculture systems. 10-m2 plots were used in a complete randomised... |

| The objective of this work was to evaluate the agronomic traits of coffee tree progenies. The experiment was set in Ouro Verde Farm, located at Campos Altos County, MG. Twenty three coffee progenies and seven control cultivars were used. These progenies are from the fourth generation of crossing between Timor Hybrid and Catuaí. The experiment was set in a randomized block design with four replicates, a total of 120 plots with 8 plants per plot. The yield of processed coffee sacks ha-1 was evaluated in eight crop years from the 2003 to the 2011 harvests. The percentage of fruits at the cherry stage, floating fruits, coffee classification (sieve above 17), income and plant vigor were evaluated in the 2010 and in the 2011 harvests. It was concluded that the... |
