Marker Assisted Selection: A Novel Approach for Crop Improvement
نویسندگان
چکیده
Integrating molecular marker technologies such as MAS into breeding strategies could become increasingly important in the coming years, to realize genetic gains with greater speed and precision. The promise of MAS for improving polygenic traits in a quick time-frame and in a cost-effective manner is still elusive. There is a wider appreciation that simply demonstrating that a complex trait can be dissected into QTLs and mapped to approximate genomic locations using DNA markers would not serve the ultimate goal of trait improvement. In facing the challenge of improving several lines for quantitative traits, MAS strategies use DNA markers in one key selection step to maximize their impact. The present paper discusses the basic requirements and the potential applications of MAS in crop plants, recent developments in MAS strategies and genotyping techniques and the significance of integrating MAS into conventional plant breeding programmes.

Marker assisted selection for the improvement of Sarjoo-52 for drought tolerance by introgression of MQTL1.1 from the source Nagina–22
Literatures have reported that a lot of drought related genes were cloned and individual gene showed positive effects under controlled stress experiments, but were not much effective in the field. Although, the progresses by conventional breeding approaches were achievable as some drought varieties have been released to the farmers in the recent years but this is not adequate to cope up with th...
