QTL analysis of flag leaf in barley (Hordeum vulgare L.) for morphological traits and chlorophyll content

Abstract: Abstract:To understand genetic patterns of the morphological and physiological traits in flag leaf of barley, a double haploid (DH) population derived from the parents Yerong and Franklin was used to determine quantitative trait loci (QTL) controlling length, width, length/width, and chlorophyll content of flag leaves. A total of 9 QTLs showing significantly additive effect were detected in 8 intervals on 5 chromosomes. The variation of individual QTL ranged from 1.9% to 20.2%. For chlorophyll content expresse… Show more

“…S42-5H and exhibited desirable performance of exotic alleles and revealed an increasing of CC by 9.83% and accounted 7.78% of the genetic variance. Xue et al (2008) who detected four putative QTLs for chlorophyll content on chromosomes 2H, 3H and 6H obtained similar result. Since, individual QTL explained the variation from 6.3% to 20.2% of the total phenotypic variation.…”

“…Our results are consistent with Zhu et al (1999) who found significant variation among DH lines within each environment and there were both positive and negative transgressive segregates. Furthermore, Xue et al (2008) studied chlorophyll content in barley and found significant transgressive segregation among DH lines.…”

“…In addition, leaf D 13 C measured before anthesis can enable selection and crosses of varieties to be made within the same season, thereby speeding up the breeding process. In our study penultimate leaf was sampled for D 13 C analysis to avoid damaging of the flag leaf (Sicher 1993;Thorne 1965;Xue et al 2008). According to Jiang et al (2006), values of D 13 C from different plant parts (flag leaf, awn and grain) were on average higher for six-row barley than those of two-row barley, suggesting a higher WUE of two-row barley compared with six-row barley under both irrigated and non-irrigated field conditions.…”

“…In barley, the importance of flag leaf in determining grain yield was also intensively studied (Xue et al, 2008). Teng et al (2004) reported that leaf chlorophyll content was positively correlated with photosynthetic capacity and high chlorophyll content as a favorable trait in rice production.…”
