AB  - Differential response of bread wheat seedlings to contrasting water regimes can be used to determine traits related to
drought tolerance. The F1 offspring from eight crosses and 11 selected parental genotypes were simultaneously grown in
hydroponic cultivation-polyethylene glycol (PEG) induced drought stress vs. control conditions. Criteria for selection of
maternal and paternal genotypes were desirable traits in terms of increased tolerance to drought: longer stem length,
longer primary root, large number of seminal roots, large root dry mass and stem dry mass, beginning of root branching
at the greatest possible distance from beginning of the root, contrasting angle of seminal roots. The traits were measured
on 14 day old seedlings: primary root length (PRL), distance to the first branch on the primary root (DFBR), number of
seminal roots (NSR), total seminal root length (TSRL), angle of seminal roots (ASR), stem length (SL), root dry mass
(RDM), stem dry mass (SDM), and the ratio of root dry mass to stem dry mass (RDM/SDM). Drought stress led to a
decrease in the mean values of all root and stem traits by 11% on average, except for RDM/SDM which was increased.
The most sensitive trait to drought stress was DFBR (25% reduction), causing root systems to branch at a shallower
depth. In conditions of induced drought stress, the strongest statistically significant correlation was found among RDM
and RDM/SDM (r = 0.794), SL and ASR (r = 0.708), RDM and TSRL (r = 0.673). The stress tolerance index had the
strongest positive correlation with the SDM, PRL, TSRL, SL, and the stress susceptibility index with the NSR. The
highest heterosis mean value was observed for PRL (24.6%) and for SL (15.6%) under drought stress. The different
directions of average heterosis in induced drought stress vs. control conditions were observed for DFBR, RDM, and
SDM, indicating differential traits to account for when planning breeding bread wheat for drought tolerance. Selected
traits as criteria for selection and favorable combinations can be incorporated into pre-breeding and breeding schemes,
directly or indirectly, aiming to achieve drought tolerance.

AB  - Genotypic variability of root and shoot traits of bread wheat (Triticum aestivum L.) at seedling stage. - Genetika, Vol 53, No.2, 687-702. The evaluation of the embryonic root and stem of bread wheat (Triticum aestivum L.) in the early stage of development (seedling stage) can be a powerful tool in wheat breeding aimed at obtaining progenies with a greater early vigour. It is revealed that genotypes with faster early vigour have produced higher biomass and grain yield. In this study, the evaluation of traits of the embryonic root and the embryonic stem of 101 bread wheat genotypes was preformed at the 10-day old seedlings. The following eight morphological traits of roots and stems were analysed: primary root length, branching interval, the number of roots, total length of lateral roots, angle of seminal roots, stem length, root dry weight and the stem dry weight. Analysed lateral roots included seminal roots. The greatest, i.e. the smallest variability of observed traits was detected in the branching interval, i.e. the stem length, respectively. The highest positive correlation was determined between the primary root length and the total length of lateral roots. The cluster analysis, based on observed traits, shows that genotypes were clearly divided into two main clusters, A and B. The two clusters essentially differed from each other in the values of the following traits: primary root length, total length of lateral roots, root dry weight, stem dry weight and the stem length. Genotypes with shorter primary and lateral roots, lower root and stem dry weight and a shorter stem were grouped in the cluster B. On the other hand, the cluster A encompassed genotypes with values of these traits above or around the average. The values of the remaining analysed traits: the angle of seminal roots, the number of lateral roots and the branching interval varied greatly between obtained clusters. The cluster analysis showed the homogeneity of genotypes originating from Serbia and the region; their values of the root and stem length and weight were mostly around and below the average. However, the values of the angle of seminal roots, number of lateral roots and the branching interval were above average.
