“…No consistent line was found for GCA effects for physiological traits under both the regimes. Similar kind of results for ELWL and MSI were presented by Dhanda and Sethi (1998). In short, inbred Line A-10.8 indicated highest GCA for achene yield per plant in both regimes and minimum plant height under no stress.…”

“…Ten plants from each replication were tagged and guarded in both normal and drought conditions. Upon maturity, plant height (cm), head diameter (cm), achene yield/plant (g), relative water content (RWC) (Malik, 1995), excised leaf water loss (ELWL; Dhanda and Sethi, 1998), and membrane stability index (MSI; Premchandra et al, 1990) were measured for 10 guarded plants at flowering stage.…”

ABSTRACT. Sunflower cannot produce high yields under waterlimiting conditions. The aim of the present study was to prevent the impediments on yield and to develop varieties with high-yield potential under water scarce conditions. For achieving this objective, it is necessary to detect parents with desirable traits that mainly depend on the action of genes controlling the trait under improvement, combining ability, and genetic makeup of the parents. Heterosis can also be used to pool the desirable genes from genetically divergent varieties and these divergent parents could be detected by molecular studies. Ten tolerant and five susceptible tester lines were selected, crossed, and tested for genetic diversity using simple sequence repeat primers. We identified two parents (A-10.8 and G-60) that showed maximum (46.7%) genetic dissimilarity. On an average 3.1 alleles per locus were detected for twenty pair of primers. Evaluation of mean values revealed that under stress conditions the mean performances of the genotypes were reduced for all traits under study. Parent A-10.8 was consistent as a good general combiner for achene yield per plant under both non-stress and stress conditions. Line A-10.8 in the hybrid A-10.8 x G-60 proved to be a good combiner as it showed negative specific combining ability (SCA) effects for plant height and internodal length and positive SCA effects for head weight, achene yield per plant, and membrane stability index. Valuable information on gene action, combining ability, and heterosis was generated, which could be used in further breeding programs.

“…Many authors have proposed excised-leaf water loss (or water retention), measured on the basis of either leaf water, fresh weight or dry weight, as a selection criterion to help improve drought tolerance (e.g., Dedio, 1975; Clarke & McCaig, 1982b; Yang, Jana & Clarke, 1991; Dhanda & Sethi, 1998; David, 2010). Indeed, significant positive relationships between excised-leaf water retention and yield have been found in studies on wheat genotypes under drought conditions (Clarke et al, 1989; Petcu, 2005; Geravandi, Farshadfar & Kahrizi, 2011), though not always (Clarke et al, 1989; Dabiry et al, 2015).…”

“…This has been studied in wheat since 1937 (Bayles, Taylor & Bartel, 1937), and in excised wheat leaves since 1969 (Salim, Todd & Stutte, 1969) as a technique for measuring drought avoidance in cereal seedlings. Since then, excised-leaf water loss (ELWL) in wheat has been used extensively as a selection tool indicating drought tolerance (e.g., Dedio, 1975; Kirkham et al, 1980; Clarke & McCaig, 1982b; Winter, Music & Porter, 1988; Yang, Jana & Clarke, 1991; Dhanda & Sethi, 1998; Golestani Araghi & Assad, 1998; Chandra & Islam, 2003; David, 2010). Thus, rate of water loss from excised leaves has been negatively associated with grain yield under drought in wheat in many reports (e.g., Clarke & McCaig, 1982a; Clarke & Townley-Smith, 1986; Clarke et al, 1989; Haley, Quick & Morgan, 1993; Chandra & Islam, 2003).…”

BackgroundWheat is widely affected by drought. Low excised-leaf water loss (ELWL) has frequently been associated with improved grain yield under drought. This study dissected the genetic control of ELWL in wheat, associated physiological, morphological and anatomical leaf traits, and compared these with yield QTLs.MethodsNinety-four hexaploid wheat (Triticum aestivum L.) doubled haploids, mapped with over 700 markers, were tested for three years for ELWL from detached leaf 4 of glasshouse-grown plants. In one experiment, stomata per unit area and leaf thickness parameters from leaf cross-sections were measured. QTLs were identified using QTLCartographer.ResultsELWL was significantly negatively correlated with leaf length, width, area and thickness. Major QTLs for ELWL during 0–3 h and 3–6 h were coincident across trials on 3A, 3B, 4B, 5B, 5D, 6B, 7A, 7B, 7D and frequently coincident (inversely) with leaf size QTLs. Yield in other trials was sometimes associated with ELWL and leaf size phenotypically and genotypically, but more frequently under non-droughted than droughted conditions. QTL coincidence showed only ELWL to be associated with drought/control yield ratio.DiscussionOur results demonstrated that measures of ELWL and leaf size were equally effective predictors of yield, and both were more useful for selecting under favourable than stressed conditions.
