Description Speed breeding is time saving based approach and is among
genetic improvement enhancers approach through genetic
recombination and fast generation reconstitution in plant
breeding. Genetic gain acceleration enables combating the
gap between demand and supply. Dagnachew et al., (2016),
have reported a positive yield and seed quality gain over the
four decades of Ethiopian chickpea research improvement
endeavor. Increasing the number of generations per unit of
time (over a given period) improves the overall efficiency in
the delivery rate of defined variety or product/s. Amy et al.,
(2018) have reported that under controlled environment of
growth chamber, speed breeding approach achieved up to 6
generations per year for spring wheat (Triticum aestivum),
durum wheat (T. durum), barley (Hordeum vulgare), chickpea
(Cicer arietinum) and pea (Pisum sativum), and 4 generations
for canola (Brassica napus), instead of 2–3 under normal
glasshouse conditions.Under uncontrolled open field condition Asnake et al
(unpublished) has reported 4 generations per year in
chickpea, with possible further potential. It was also noted
that the approach can easily be adopted, integrated with
other conventional and/or advanced breeding approaches
like molecular breeding. This manual tries to elaborate the
approaches /which is flexible/ in chickpea speed breeding
with the goal to achieve multiple generations per year
without losing breeding values (the useful attributes of the
products). Single Seed Decent (SSD) Technique is preferred
approach along the speeding generation to be made in the
course.
