“…As such, these markers provide an alternative to intensive manual labor in the field. Ma et al (2013) showed that different restorers might carry different Rf genes. We therefore doubt that the restorer lines selected by the two markers will be limited and decreased.…”

“…Perhaps, when diverse eggplant nuclear genomes are combined with the cytoplasm of S. violaceum, a different number of genetic loci and/or gene interactions are involved in fertility restoration, resulting in different segregation ratios. This is supported from studies in CMS rape-seed, rice and pepper where the gene interactions between the fertility restoring loci varied according to the restorer line used in the crosses (Ma et al, 2013;Pahwa, S. K. Banga, Gogna, & S. S. Banga, 2004;Sarkar, Zaman, & Singh, 2002). In addition, Hazra et al (2008) reported a strong genotypic effect on the expressivity of the genes involved in eggplant GMS and fertility restoration.…”

A functional cytoplasmic male sterile (CMS) eggplant line carrying the cytoplasm of Solanum violaceum was developed in the past, but the fertility restoring genes (Rf-genes) were not identified. This work aimed to produce the CMS lines of three Hellenic eggplant cultivars (viz., 'Langada', 'Emi' and 'Tsakoniki') using the cytoplasm of S. violaceum and study the inheritance of the Rf-genes. The respective CMS eggplant lines were developed by the backcross method and examined for their fertility parameters. The results demonstrated that female fertility was not affected by the cytoplasm of S. violaceum. In contrast, the occurrence of three male fertility phenotypes (male sterile, male fertile and potentially male fertile) indicated that male fertility was affected by nuclear/cytoplasmic interactions. Male sterile plants were characterized by indehiscent anthers, low pollen viability and abnormal anther morphology. Male fertile plants formed dehiscent anthers with high pollen viability and normal morphology. Potentially male fertile plants initially formed dehiscent anthers, but in later stages formed exclusively indehiscent anthers. Male fertile plants were obtained in the advanced backcross populations of CMS 'Tsakoniki', but not in CMS 'Langada' and CMS 'Emi'. The genetic analysis of fertility restoration indicated that male fertility in the genetic background of cv. 'Tsakoniki' is controlled by one essential genetic locus, affected by a secondary modifying locus. Molecular analysis of cp-DNA and mt-DNA in the CMS lines indicated maternal inheritance of the cytoplasm organelles. Our findings demonstrate that the genotype of the eggplant parent can affect the expression of CMS as well as fertility restoration.

“…Using both approaches, 10 markers were found associated with QTLs for fertility restoration. This study identified common markers and consistent QTLs for hybrid breeding in pigeonpea as evident in a number of crop species such as rice ( Liu et al, 2004 ; Ahmadikhah and Karlov, 2006 ; Wang et al, 2006 ), maize ( Zhang et al, 2006 ), cotton ( Liu et al, 2003 ), pepper ( Ma et al, 2013 ) and petunia ( Bentolia and Hanson, 2001 ).…”

Cytoplasmic genic male sterility (CGMS) based hybrid technology has demonstrated its immense potential in increasing the productivity of various crops, including pigeonpea. This technology has shown promise for breaking the long-standing yield stagnation in pigeonpea. There are difficulties in commercial hybrid seed production due to non-availability of field-oriented technologies such as time-bound assessment of genetic purity of hybrid seeds. Besides this, there are other routine breeding activities which are labor oriented and need more resources. These include breeding and maintenance of new fertility restorers and maintainer lines, diversification of cytoplasm, and incorporation of biotic and abiotic stress resistances. The recent progress in genomics research could accelerate the existing traditional efforts to strengthen the hybrid breeding technology. Marker based seed purity assessment, identification of heterotic groups; selection of new fertility restorers are few areas which have already been initiated. In this paper efforts have been made to identify critical areas and opportunities where genomics can play a leading role and assist breeders in accelerating various activities related to breeding and commercialization of pigeonpea hybrids.
