Now a days, speed breeding is becoming famous for rapid varietal development through rapid generation advancement.
However, it's applicability and feasibility for everyone and everywhere is still not wider. What you think about it? How will it be useful in future breeding for crop improvement.?
Dear Parmeshwar K. Sahu Any breeding scheme based on rapid turn over of generation cycle, ultimately resilting in rapid attainment of final outcomes may be referred to as speed breeding. Its concept is rooted in haploidy breeding through which completely homozygous lines are derived from haploids by using colchicine in a single generation. Recently Australian breeders have used it to develop a wheat variety "DS Faraday". The details of speed breeding can be accessed at the links goven below:

Thanks!
Definitely speed breeding is need of an hour the protoplast fusion, double haploid production are some of the techniques can be used to achieve speed
Speed breeding is an effective way to cut short breeding time. It allows you to reach homozygosity rapidly. For example, 3 growth cycles will allow you to reach F6 in 2 years only! However, to harness the benefit, marker assisted selection must be coupled with speed breeding. Early generation identification of homozygous loci can be achieved by MAS. These lines need to be advanced in generation through speed breeding. The same applies in case of marker assisted back cross breeding. So, it is a real powerful tool in crop improvement.
Speed breeding is not a new concept but it is widely used in wheat
In another crops, there are some problems like selection of IPS in generation advancement process where plant can't fully express their performance so problem in selection.
It is true that for reduce time in varietal development, this approach will be helpful lot
For successful speed breeding, you must not rely on the character expression by the plants. That is why marker assisted selection should be an integral part of speed breeding.
Production of haploids is also one way to speed breeding and it is highly relevant in perennial crops.
