Identification of genes responsible for complex traits has been revolutionized with the advent and association of high throughput sequencing with association studies. GWAS takes the full advantage of ancient recombination events occurred in the natural population and exploits simple association of polymorphism with the trait of interest. Further, the genetic basis of phenotypic variations is detected by rapid highthroughput sequencing, accelerating the genome assisted breeding. The high density SNPs generated through GWAS allow whole genome scanning to identify haplotype blocks correlated with desired QTLs, thereby establishing itself as a major plant breeding tool.Keywords

The effect of continuous application of fertilizers and amendments on wheat yield and nutrients in an acid Alfisol during rabi (2018-19) was evaluated in an ongoing long-term field experiment initiated in 1972 at the research farm of the Department of Soil Science, CSK HPKV, Palampur.The soil of the experimental area was acidic (pH 5.8), silt loam in texture and classified taxonomically as “Typic Hapludalf”. The highest productivity of wheat was recorded in the treatment comprising 100% NPK + FYM and was statistically at par with treatment receiving 100% NPK with lime. Continuous sole application of N resulted in zero yield. The significantly superior available N and K were registered in treatment receiving 100% NPK + FYM. However, the highest available P was recorded in treatment where NPK at 150 per cent of the recommended dose were applied. The Zn application along with 100% NPK registered the highest value (4.19 mg kg-1) of DTPA extractable Zn and application of 100% NPK + FYM recorded the highest value of DTPA extractable Fe, Cu, and Mn (36.8, 2.26, and 39.65 mg kg-1, respectively). Overall, 100% NPK+ FYM was found to be the best treatment to increase the wheat productivity and maintain nutrients status in the soil on long-term basis.Keywords
