Article Synopsis
  • Grain weight (GW) significantly impacts cereal crop yield, and a study analyzed 105 backcross introgression lines (BILs) and 90 chromosome segment substitution lines (CSSLs) over four wet seasons to evaluate thousand-grain weight (TGW).
  • The study identified various NPS and NPK lines with either positive or negative impacts on TGW, and through QTL mapping, 13 QTLs were detected in NPS with notable effects on grain weight, while 10 were found in NPK.
  • Notably, a specific grain weight QTL was fine-mapped to a 31 kb region, which includes the GRAS transcription factor gene, suggesting its potential role in enhancing grain weight in the

Crop improvement for Nitrogen Use Efficiency (NUE) requires a well-defined phenotype and genotype, especially for different N-forms. As N-supply enhances growth, we comprehensively evaluated 25 commonly measured phenotypic parameters for N response using 4 N treatments in six indica rice genotypes. For this, 32 replicate potted plants were grown in the green-house on nutrient-depleted sand.

Bacterial blight (BB) and fungal blast diseases are the major biotic constraints that limit rice productivity. To sustain yield improvement in rice, it is necessary to developed yield potential of the rice varieties by incorporation of biotic stress resistance genes. Tellahamsa is a well-adapted popular high yielding rice variety in Telangana state, India.
