Genetic Variability of Pigeonpea (Cajanus cajan (L.) Millsp.) for Water Logging and Salinity Tolerance under in vitro and in vivo Conditions
Pigeonpea (Cajanus cajan (L.) Millsp.) genotypes acquired from diverse sources, were screened for water logging and salinity tolerance under laboratory and field conditions. Analysis of variance revealed significant ...
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 ...
An “Axiom Cajanus SNP Array” based high density genetic map and QTL mapping for high-selfing flower and seed quality traits in pigeonpea
Background
Pigeonpea has considerable extent of insect-aided natural out-crossing that impedes genetic purity of seeds. Pre-anthesis cleistogamy in pigeonpea promotes self-pollination which helps in maintaining genetic ...
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 ...
Gene action and combining ability estimates using cytoplasmic-genic male sterile lines to develop pigeonpea hybrids for rainfed condition
Pigeonpea is the major source of vegetable protein in
Indian diet. About 72.5 percent area and 62.5 production of
world’s pigeonpea is in India.Pigeonpea is the only food legume
where cytoplasmic-genic male sterility is ...
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 ...
