Molecular diversity based heterotic groups in pigeonpea [Cajanus cajan (L.) Millsp.]
A set of 155 hybrid parents was characterized at molecular
level using 24 simple sequence repeat (SSR) markers.The
number of alleles amplified ranged from 3 to 41 at an average
of 14.5 alleles per marker and mean ...
Strategies for breeding, production and promotion of pigeonpea hybrids in India
With the release of GTH-1 the world’s first CMS hybrid in
pigeonpea [Cajanus cajan (L.) Millsp.], the breeding of
hybrids in this important pulse crop has become a reality. At present three early duration pigeonpea hybrids ...
Mechanism of water-logging tolerance in pigeonpea
A study was undertaken to identify the morphophysiological
traits associated with water-logging tolerance in pigeonpea [Cajanus cajan L. (Millsp.)].The formation of
aerenchyma cells, lenticels, and adventitious roots in ...
Combining ability studies of pigeonpea CGMS lines with an obcordate leaf marker
Hybrid pigeonpea [Cajanus cajan (L.) Millsp.] breeding technology based on CGMS was recently developed. A program was initiated to track the purity of female parental lines by incorporating an obcordate leaf shape marker ...
Believe it or not, hybrid technology is the only way to enhance pigeonpea yields
Pigeonpea yields have remainedunacceptably low over the past five decades and efforts to break this plateau through breeding pure line cultivars did not succeed in its mission. Key successes in breeding stable cytoplasmic ...
Association of nad7a Gene with Cytoplasmic Male Sterility in Pigeonpea
Cytoplasmic male sterility (CMS) has been exploited in the commercial pigeonpea [Cajanus cajan (L.) Millsp.] hybrid breeding system; however, the molecular mechanism behind this system is unknown. To understand the underlying ...
From concept to field: evolution of hybrid pigeonpea technology in India
The role of hybrid vigour in the enhancement of productivity is well recognized. Its application, however, has been restricted to a few crops and legume breeders could never take its advantage due to various seed production ...
Genetic Enhancement of Seed Proteins in Pigeonpea – Methodologies, Accomplishments, and Opportunities
The food and nutritional security in India is assuming alarming situation as the protein availability in the decade
ending 2009 has reduced from the recommended 46 g/head/day to < 25 g. This is leading a wide spread ...
Stability of Cytoplasmic Genetic Male Sterility and Fertility Restoration in Pigeonpea
In cytoplasmic genetic male sterility-based (CGMS) hybrid seed
production, instability of expression of male-sterility and fertility
restoration across a wide range of environments are two of the
major difficulties. ...
A Short-Cut Approach for Breeding Pigeonpea Hybrids With Tolerance to Biotic and Abiotic Stresses
Lack of stability associated with low productivity have remained key production constraints in pigeonpea for decades.
In this paper, efforts have been made to address these two issues together by breeding high yielding ...
