“…Leaf chlorosis is a direct symptom of flooding that has been successfully applied in wheat (Boru et al 2001), soybean (Cornelious et al 2005) and barley (Li et al 2008). In our study, a MFVW that integrates a wilting index, a chlorosis score and the dead leaf proportion of waterlogged plants was deployed to measure WT.…”

Waterlogging tolerance (WT) is a major objective in chrysanthemum breeding programs, and although certain genotypes with different tolerance levels have been identified, their value as parents for WT breeding is unknown. Here, twelve F 1 crosses derived from an incomplete diallel mating scheme were conducted to investigate combining ability and heterosis for WT and their relationships with parental genetic distance. The results showed that the membership function value of waterlogging (MFVW) was controlled by additive and non-additive gene effects, whereas other growth and biomass traits were mainly controlled by non-additive gene effects. The estimated broad and narrow sense heritabilities of the MFVW were 97.5 and 51.5%, respectively. Combining ability analyses indicated that 'Nannong Xuefeng' showing the largest general combining ability (GCA) effect for the MFVW was the best combiner, and identified several best cross combinations with high positive specific combining ability (SCA) effects for most WT-related traits. Mid-and high-parent heterosis occurred widely. The three distance measures, based on phenotypic traits (PD), molecular markers (GD) and markers linked with quantitative trait loci (QTL-GD), presented a nonsignificant correlation with combining ability except for the GD with GCA for the relative root fresh weight. The correlations between the QTL-GD and heterosis were significant for certain traits and generally higher than that of the PD or GD and heterosis. The SCA effects were positively correlated with heterosis for most of the WT traits (0.51 B r B 0.80). The findings benefit understanding the inheritance mode and then achieving desirable improvement for WT in chrysanthemum.

“…In previous studies germination rate and plant survival have been used as characteristics of waterlogging tolerance in barley (Li et al, 2008) and rice (Nandi et al, 1997), as they visibly respond to waterlogging. In the current study, plant parameters measured under anaerobic conditions relative to aerobic conditions were the other main parameters for investigating waterlogging tolerance.…”

Waterlogging is a widespread problem and one of the major yield-limiting factors of wheat in some parts of the coastal plains of Turkey. The object of this study was to identify waterlogging-tolerant cultivars in bread wheat. Twenty-four bread-wheat genotypes were tested under aerobic and anaerobic conditions to determine shoot dry weight gain, root dry weight gain, total dry weight gain, dry leaf weight, specific dry leaf weight, chlorophyll content, carotenoid content, transpiration and photosynthesis rates, and their tolerance indices. A complete randomized block design with three replications was conducted for both aerobic and anaerobic conditions. The current study clearly demonstrated that wheat seedlings growing under anaerobic conditions had significantly lower shoot dry weight, root dry weight, total dry biomass weight, leaf dry weight, specific leaf dry weight, chlorophyll a, chlorophyll b, chlorophyll a + b, and carotenoid content, and photosynthesis and transpiration rates. There were significant correlations between total dry weight gain and shoot dry weight gain and between chlorophyll a and specific leaf dry weight. Wheat cultivars had different tolerance indices for the investigated plant parameters. Further studies are needed to confirm which tolerance index is significantly correlated with seed yield and which one could be used as a selection criterion under field conditions.

“…Furthermore, QTL-QY2 and also QTL-QY4 on 4H are located in similar positions to a QTL identified in TX9425 9 cv. Yerong by Li et al (2008) based on dry matter reduction after 3 weeks of waterlogging stress. QY is used as an indirect way of predicting the biomass growth reduction of waterlogged seedlings and the genes responsible may be the same.…”

“…With only seven chromosomes, barley has been widely used in different QTL analyses (Ahmed et al 2013;Close et al 2009) and also for WLT (Li et al 2013). Li et al (2008) identified several QTL linked to leaf chlorosis, plant survival and plant residual biomass, while Zhou et al (2012) found four QTLs linked to an index calculated from scores of leaf chlorosis and plant survival of waterlogged plants in outdoor tanks filled with soil. The latter method was used by Zhou (2011) to obtain more accurate phenotyping.…”

“…The methods currently used are indices based on leaf chlorosis (Li et al 2008), germination ability (Takeda and Fukuyama 1987), biomass growth reduction (Zhou et al 2012) and yield components (Xue et al 2010;Walker et al 2013). Most of these traits are difficult to use in breeding, especially in field selection with high genotype-by-environment interaction.…”

Waterlogging is a major factor limiting barley grain yield worldwide. Climate change will likely increase this water stress in Northern Europe. Breeding for waterlogging tolerance (WLT), as for other abiotic stresses, is difficult, but identification of genetic markers linked to genes affecting WLT could facilitate the breeding process. To identify a suitable marker population, parents of 14 double-haploid (DH) barley populations were tested for segregation of biomass growth reduction in waterlogged soil. The most interesting was found in the offspring from crossing cv. Psaknon and breeding line (SLUdt1398 9 Mona 4 ). Hence, 120 DH-lines derived from this cross were phenotyped for the chlorophyll fluorescence parameter quantum yield (QY) of electron transport of PSII from leaves of hypoxia-stressed plants and further genotyped with 384-SNP Illumina GoldenGate Bead Array. Five quantitative trait loci (QTL) for QY, with a narrow sense heritability of 0.87, were identified on chromosomes 4, 6 and 7H. They had additive effects ranging from 0.74 to 1.35 % with LOD scores from 3 to 12 and explained variance from 6 to 29 %. The major alleles for high QY were from cv. Psaknon; i.e., QY was low if the alleles from cv. Psaknon were not present. Based on leaf necrosis and residual biomass data, the four most interesting QTL may be also in two other populations with completely different progeny, which shows a certain stability of these QTL. The possibility of using marker assistant selection for WLT is discussed, as is possible concurrent improvement of drought tolerance and grain yield.
