Identification and characterization of QTL for spike morphological traits, plant height and heading date derived from the D genome of natural and resynthetic allohexaploid wheat

Raden I, Nugroho CC. Syahrani. 2017. Identification and characterization of morphological diversity of Lemba (Curculigo latifolia) in East Kalimantan, Indonesia. Biodiversitas 18: 1367-1376. Lemba (Curculigo latifolia) is Kalimantanâ€™s land prospective for commercial cultivation because its leaf fiber has been traditionally utilized as fiber source for ulap doyo woven cloth; its fruit as sweetener; and its root as medicinal herb. To this days, only a few of research has been conducted on lemba in East Kalimantan or even in Indonesia, including studies on lemba plant phenotype suitable for weaving material. Thus, a research about identification and morphological characterization of lemba cultivars is necessary to identify and characterize lemba plant in East Kalimantan to reveal phenotypic variability in both quantitative and qualitative traits that can be utilized as the source of germplasm for the plant breeding program. This study was carried out in three Sub-districts, i.e.: Tenggarong Sub-district (Kutai Kartanegara District), Kota Bangun Subdistrict (Kutai Kartanegara District), and Jempang Sub-district (West Kutai District). Data collection was done by observation, and measurement of quantitative and qualitative traits of lemba plant. Descriptive analysis was applied on the morphological traits data, while correlation analysis was performed to reveal relationship between the qualitative and quantitative morphological traits by using software Minitab v.14.12. Phenotypic variability was determined based on the standard deviation. Principal component analysis and cluster analysis of the data were performed by using software SPSS v.11.6. The variance value of the 33 observed lemba plant accessions from the three Sub-districts indicated that the phenotypic variability of the qualitative traits was narrow while that of the quantitative traits was broad. There are three principal components that account for the observed variability with a cumulative variance of 96% which is obtained from 19 observed traits. Cluster analysis at similarity 95% indicates that there are five lemba accessions groups based on only qualitative, only quantitative, or based on combined qualitative and quantitative traits.

Miscanthus is a C4 perennial energy crop distributed in various regions of China. Miscanthus sinensis has a high potential for biomass production, great adaptability to marginal land and tolerance to stress environmental. It's very important for the production and development of biofuel to review both the morphological and geographical traits on yield. However, the relevance of biomass yield and the geographical position of habitat are still not well known. In the present study, investigations of heading date, plant height, stem number and dry biomass per plant were carried out to calculate the influence of the morphological traits on yield. The investigation was based on 327 Miscanthus sinensis accessions collected from 21 provinces from all over China. The analysis was carried out on the basis of the two-year field experiment. The data for the second year was used to perform the analysis of variance and regression. Statistical data analysis was also performed on the variation of the biomass and morphological traits over successive period of study. The results showed that the growth included plant height and stem number in the following year was much better than the first year, particularly the biomass. Regression analysis revealed that latitude, plant height, and stem number were the key morphological traits that influence the biomass production. Also, heading date and elevation were found to be highly correlated to yield structure. These results demonstrated that the growth and yield were strongly influenced by geographical location, and apart from morphological traits, geographical traits were important factors that affect biomass.

Hulled Wheat

Spelt (TriticumspeltaL.) is hulled wheat which was widely cultivated in Spain until the first half of the 20th century and is still cultivated in Asturias (northern Spain). Much of the variability of this species has been preserved, but little evaluation has been carried out. We describe the characterization of some of these spelt lines for several quantitative traits, including plant height and awnedness.

Fhb Resistance

Fusarium head blight (FHB) is a devastating disease that causes significant reductions in yield and quality in wheat and barley. Barley grains infected with deoxynivalenol (DON), a vomitoxin produced by Fusarium graminearum, are rejected for malting and brewing. Among six-rowed barley cultivars tested thus far, only cv. Chevron exhibited resistance. This study was conducted to map genes and to identify DNA markers for marker-assisted breeding for FHB resistance in cv. Chevron with restriction fragment length polymorphism (RFLP) markers. A doubled haploid (DH) population was created from a cross between cv. Chevron and susceptible cv. Stander. Seven field experiments were conducted in four different locations in 2 years. A RFLP map containing 211 loci and covering over 1,000 centimorgans (cM) of the genome was used to map quantitative trait loci (QTL) associated with relatively low FHB severity and DON concentration. Morphological traits differing between the parents were also measured: heading date, plant height, spike angle, number of nodes per cm of rachis in the spike, and kernel plumpness. Many of the QTL for FHB and DON coincided with QTLs for these morphological traits. The “fix-QTL” algorithm in Mapmaker QTL was used to remove the part of the variance for FHB resistance that may be explained by heading date or plant height. Results from this study suggest that QTLs with major effects for FHB resistance probably do not exist in cv. Chevron. Three QTL intervals, Xcmwg706-Xbcd441 on chromosome 1H, Xbcd307b-Xcdo684b on chromosome 2H, and Xcdo959b-Xabg472 on chromosome 4H, that are not associated with late heading or height may be useful for marker-assisted selection.
