The response of common bean to drought is still not sufficiently well characterized due to its genetic complexity and its diverse, often ambiguous, phenotypic effects. Understanding these mechanisms is thus of fundamental importance for developing varieties that are better adapted to such stress conditions. In the chapter, we present research that provides an insight into the morpho-physiological adaptation and its underlying molecular changes in common bean plants exposed to drought. We include our contribution to establishing the basis for breeding of common bean with greater tolerance to this abiotic stress that uses molecular markers and identification of quantitative trait loci (QTLs).

COBISS.SI-ID: 5979496This publication presents a complex and comprehensive inventory of the genetic resources of the beans at the Slovenian Plant Genetic Bank of the Agricultural Institute of Slovenia. Using morphometric parameters, we evaluated the collection of genetic resources of ordinary (Phaseolus vulgaris L.) and runner beans (Phaseolus coccineus L.). With the prescribed descriptors (UPOV, CPVO, IBPGR, PHASELIEU) for seeds of the species Phaseolus sp. and extensive picture material we characterize and describe 955 common beans and 47 accessions of runner beans. The book is intended for a wider circle of readers, from gardeners, farmers and students to breeders and researchers, who can thus acquaint themselves with the collected heredity and a large collection stored for future generations at the Agricultural Institute of Slovenia. We dedicate this book to all researchers and researchers who have worked and are still active in the field of genetic resources of agricultural plants and thus take care of the preservation of the natural and cultural heritage in Slovenia.
F.27 Contribution to preserving/protecting natural and cultural heritage
COBISS.SI-ID: 297596928We have developed a method for discrimination between abiotic and biotic drought stress in tomatoes using hyperspectral imaging. The achievement describes a developed model for data processing. The method enables remote detection as well as inspection of large areas and detection of pests in the early stages. This is important for effective pest control. We estimate that the developed method and model for data processing will play an important role in detection of diseases and pests in modern agricultural production in the future.
F.09 Development of a new technological process or technology
COBISS.SI-ID: 5710952The objective of the present study was to determine the composition of fatty acids in the whole grain, hulls, bran and the light flour of common (Fagopyrum esculentum Moench) and Tartary (Fagopyrum tataricum (L.) Gaertn) buckwheat harvested in two consecutive years. Fatty acid composition for different milling fractions was determined as methyl esters using gas chromatography. Nine fatty acids were determined: lauric (12:0), myristic (14:0), palmitic (16:0), palmitoleic (16:1), stearic (18:0), oleic (C18:1; n-9), linoleic (C18:2; n-6), ?-linolenic (C18:3; n-3) and arachidic (20:0) acid. The highest relative content was determined for linoleic acid (from 35.54 to 47.57%), followed by oleic acid (from 20.96 to 40.76%) and palmitic acid (from 13.86 to 26.42%). The total fatty acid content was the highest in bran (up to 62.64 g/kg), followed by whole grains (up to 22.93 g/kg), light flour (up to 9.69 g/kg) and hulls (up to 5.87 g/kg). Saturated fatty acid content was the highest in the hulls and the lowest in the bran. Polyunsaturated fatty acid content was the highest in light flour. High positive correlations were found between saturated fatty acids with 18 carbon atoms or less.

COBISS.SI-ID: 5918568In an extensive work co-authors described in detail various areas of biological plant protection and other low-risk plant protection methods. The work comprises more than two hundred and thirty pages and deals with a wide range of different topics of 'non-chemical' plant protection and as such presents a good overview of the topic for a wide readership. Reduction of pesticide use and increase of food self-sufficiency (which is critically low especially in vegetable production!) are important goals in Slovenian agricultural policy. From this perspective the scientific monograph contributed significantly to Slovenia’s (agriculture) development by introducing environmentally safe and at the same time economically acceptable plant protection measures.
