Drought stress is the major constraint to rice ( Oryza sativa L.) production and yield stability in rainfed ecosystems. Identifying genomic regions contributing drought resistance will help develop cultivars suitable for through molecular marker assisted breeding. Quantitative trait loci (QTLs) linked plant water indicators, phenology traits under irrigated conditions were mapped by means of a doubled‐haploid (DH) population 154 lines from cross CT9993‐5‐10‐1‐M/IR62266‐42‐6‐2. The DH...
<i>Melia dubia</i> is one of the promising farm forestry tree species in semiarid regions to provide raw materials for industries and restore soil fertility, besides contributing regional carbon budget. An optimal stand density will result higher pulpwood productivity ecological restoration. This study aimed optimize plantation a region by studying four densities, viz., 4444 trees ha<sup>-1</sup>, 2500 2000 2222 obtaining yield find...
Abstract Eucalyptus is planted worldwide for raw material in paper and rayon industry. It a potential out-crosser the natural populations are highly heterogeneous displaying strong inbreeding depression. hybrids have been intensively utilized their vigor, higher wood quality resistance to diseases. Identification of species hybridization predominantly based on morphological characters not always reliable. Hence, DNA marker identification hybrid validation an important efficient tool breeding...
Eucalyptus is the most economically important hardwood plantation tree cultivated in tropical and subtropical countries. Inter-simple sequence repeat (ISSR) markers were used to evaluate genetic relationships within between individuals of six species. A total 583 loci (265 1535 bp) amplified from 149 belonging species using seven ISSR primers (two three nucleotide repeats anchored with one or two nucleotides at 3′ 5′ region). The fragments indicated significant polymorphism diversity among...
The invasive gall wasp Leptocybe invasa (Hymenoptera: Eulophidae) induces galls on the shoots of Eucalyptus camaldulensis Dehnh. and E. tereticornis Sm. damage nursery seedlings young plantations coppice shoots. magnitude in nurseries necessitates increased efforts to reduce incidence impacts pest. Identification feasible appropriate management methods will help reducing high cost containing pest outbreak situations avoid loss planting material by state Forest Departments, Corporations...
Clonal forestry captures genetic gain generated by skillful selection and is now well recognized as a method for mass production of desired trees to obtain increased economic benefits. In Eucalyptus, clonal plantations have enhanced the productivity twofold, compared unimproved seed origin. The present investigation was carried out assess relationship 41 eucalypt clones using intersimple sequence repeat (ISSR) marker system. ISSR-derived dendrogram principal coordinate analysis (PCA)...
Inter Simple Sequence Repeats (ISSR) technique was deployed for the estimation of genetic diversity in18 Leucaena leucocephala provenances. Seeds these provenances were collected from across country and planted at a single location in South India. To estimate diversity/ polymorphism, DNA extracted through Cetyl Trimethyl Ammonium Bromide (CTAB) method, visualized analyzed bands on UV trans- illuminator gel doc (α-imager 3.2). Totally ten ISSR primers used this study. Among them, eight...

<i>Eucalyptus</i> is one of the highly economic tree species in developing countries like India. In present investigation, experiments on optimizing plant growth regulators micropropagation promising inter specific hybrid clones namely TNPL 191(<i>E. camaldulensis</i>× <i>E. teriticornis</i>), 192 (<i>E. camaldulensis</i> × pellita</i>) and intra clone 193...
Success of the containerized clonal plants production relies largely on rooting substrates.The partially decomposed coconut residue (coir pith) is being used for seedlings/ clones horticulture and plantation development.A study was conducted to find out possibility including sugarcane residue-sugarcane bagassse pith (SBP) as a substrate or partial substitution coir (CCP) pulpwood production.These two residues were mixed in different proportions (100, 75, 50 25 %), co-composted using...
