Exploring genetic divergence and marker-trait associations for leaffolder (Guenee) resistance in rice landraces.

Rice production faces a significant threat from the rice leaffolder, . To address this challenge, growing resistant varieties stands out as a sustainable and eco-friendly pest management strategy. This necessitates identifying resistant sources and understanding their inheritance patterns through employing DNA markers for marker-assisted resistance breeding.

Multi-environment evaluation of rice genotypes: impact of weather and culm biochemical parameters against sheath blight infection.

Introduction: Sheath blight caused by is one of the major diseases of rice, causing widespread crop losses. The use of semi-dwarf rice varieties in the ongoing nutrient-intensive rice cultivation system has further accentuated the incidence of the disease. An ideal solution to this problem would be identifying a stable sheath blight-tolerant genotype.

A Comprehensive Genome-Wide Investigation of the Cytochrome 71 () Gene Family: Revealing the Impact of Promoter and Gene Variants (Ser33Leu) of on Yield-Related Traits in Indica Rice ( L.).

The cytochrome P450 (CYP450) gene family plays a critical role in plant growth and developmental processes, nutrition, and detoxification of xenobiotics in plants. In the present research, a comprehensive set of 105 family genes was pinpointed within the genome of indica rice. These genes were categorized into twelve distinct subfamilies, where members within the same subgroup exhibited comparable gene structures and conserved motifs.

Unravelling genetic architecture and development of core set from elite rice lines using yield-related candidate gene markers.

Unlabelled: Assessing genetic diversity and development of a core set of elite breeding lines is a prerequisite for selective hybridization programes intended to improve the yield potential in rice. In the present study, the genetic diversity of newly developed elite lines derived from and crosses were estimated by 38 reported molecular markers. The markers used in the study consist of 24 gene-based and 14 random markers related to grain yield-related QTLs distributed across the rice genome.

Multi-trait association study identifies loci associated with tolerance of low phosphorus in Oryza sativa and its wild relatives.

We studied variation in adaptive traits and genetic association to understand the low P responses, including the symbiotic association of arbuscular mycorrhizal (AM) fungal colonization in Oryza species (O. sativa, O. nivara, and O.

Non-destructive phenotyping for early seedling vigor in direct-seeded rice.

Background: Early seedling vigor is an essential trait of direct-seeded rice. It helps the seedlings to compete with weeds for water and nutrient availability, and contributes to better seedling establishment during the initial phase of crop growth. Seedling vigor is a complex trait, and phenotyping by a destructive method limits the improvement of this trait through traditional breeding.

Correction: Use of molecular markers in identification and characterization of resistance to rice blast in India.

Evaluations of allelopathic effect of Echinochloa colona weed on rice (Oryza sativa L. 'Vandana').

Echinochloa colona (L.) Link is a very problematic weed in up land and medium land rice causing significant reduction in yield. In the present investigation, laboratory and field experiments were conducted to evaluate the nature of interaction E.
