Molecular markers and their uses for plant biotechnology.
Efficiency of marker-assisted selection for ascochyta blight in chickpea is a good article comparing the price & effectiveness of MAS in chickpea crop.
Dear Dr. B Parthipan,
I would like to thank you for your questions.
I have 2 publication about the marker assisted selection application in wheat and barley. I hope that could help you.
with kind regards
Khaled

Sir, There are so many. On exactly which aspect do you need? I mean Marker for resistance, yield or any other trait.
Regards,
Respected Dr. A.K. Mukherjee
I express my sincere thanks to you for your reply. Sir this topic is included in M.Sc syllabus. So I need general article for molecular markers and their applications-marker assisted selection of qualitative and quantitative traits. with regards Parthipan

I think that a MAS against traits inherited by many QTLs can be problematic, even we have medium or larger effect QTLs. We haaaave not information about the right number of QTLs, from Frontana we found 6-7 QTLs when a large variability for heading was found, anf 15 when the background noise was lower from the same resistance source, but only 4-5 days difference in heading of the mapping population. Additionally we have only very limited information beetween cooperation of QTLs, we found sometimes increasing susceptibility, but also transgressive segregation. However, the phenotypic selection considers automatically all effect and interactions. For practical breeding this is more effective now. And much cheaper. However, when the genetic background will be more clear and we will know the genes behind the QTLs, the situation may change. At present, however, no resistant genes against FHB is known. There is a long way before us, and I think, before you.
