    Abstract Proteins, inevitable for nutritional security of human beings and legumes, by far, are the cheapest source of this vital nutrient. The escalating prices and never halting population growth limit the per capita availability of protein‐rich legumes. In view of limited land resource and need to grow other food crops, the greater protein harvests are possible only by increasing the protein levels of popularly grown legumes. In this context, attempts were made for raising the protein content in pigeonpea [Cajanus cajan (L.) Millsp.] through traditional plant breeding tools. For this, the high‐protein trait was successfully transferred from wild relatives of pigeonpea to the cultivated types. In the derived inbred lines, the protein content was significantly enhanced from 20% ‐ 22% to 28% ‐ 30%. Two high‐protein lines HPL 40 and HPL 8 also produced 2100 and 1660 kg/ha grain yield, respectively. This simply means that, in comparison with traditional cultivars, the cultivation of high‐protein lines will provide additional 100 kg/ha of digestible protein to the farming family. This paper, besides describing the breeding procedures, also discusses the accomplishments of this breeding endeavour with respect to its various nutritional and biological properties.

    Abstract Yield is polygenically inherited and highly influenced by G x E interaction higher magnitude of G x E interaction among genotypes invalidates the fitness of genotypes across the environments. Hence, quantification G x E interaction and identification of stable genotypes across environments will enhance production and productivity of pigeonpea. The stable performance of the thirty three advanced medium duration lines of pigeonpea along with six check varieties across the seasons were examined during kharif-2017, 2018 and 2019 at Zonal Agricultural Research Station, (ZARS) Kalaburagi, Karnataka, India. The advanced medium duration genotypes was contributed by six research stations belongs six states in India. Considering all stability parameters the genotype ICPL 20108 found stable, high yielding and had desirable agronomic traits. The genotype GRG 177 though ranked first for mean yield, it exhibited nonlinear regression indicating highly sensitiveness to different environments. The genotype GRG 152 had second highest mean yield with bi<1 (bi= regression) and non significant deviation from regression co-efficient indicating its specific suitability to unfavorable/poor/low input environments. The genotypes BDN-2014-1, ICPL 20098 and AGL-1603-4 had average yield above population mean and exhibited stable performance across environments.

    Abstract Background: Restoration of fertility (Rf) is an important trait for pigeonpea hybrid breeding. Few coarse quantitative trait locus (QTL) studies conducted in the past identified QTLs with large confidence intervals on the genetic map and could not provide any information on possible genes responsible for Rf in pigeonpea. Therefore, a larger population comprising of 369 F
    Results: A genetic map with 4867 markers was developed and a total of four QTLs for Rf were identified. While one major effect QTL (qRf8.1) was co-localized with the QTL identified in two previous studies and its size was refined from 1.2 Mb to 0.41 Mb. Further analysis of qRf8.1 QTL with genome sequence provided 20 genes including two genes namely flowering locus protein T and 2-oxoglutarate/Fe (II)-dependent dioxygenases (2-ODDs) superfamily protein with known function in the restoration of fertility.
    Conclusion: The qRf8.1 QTL and the potential candidate genes present in this QTL will be valuable for genomics-assisted breeding and identification of causal genes/nucleotides for the restoration of fertility in the hybrid breeding program of pigeonpea.

    Abstract Key message: The review outlines advances in pigeonpea genomics, breeding and seed delivery systems to achieve yield gains at farmers' field. Pigeonpea is a nutritious and stress-tolerant grain legume crop of tropical and subtropical regions. Decades of breeding efforts in pigeonpea have resulted in development of a number of high-yielding cultivars. Of late, the development of CMS-based hybrid technology has allowed the exploitation of heterosis for yield enhancement in this crop. Despite these positive developments, the actual on-farm yield of pigeonpea is still well below its potential productivity. Growing needs for high and sustainable pigeonpea yields motivate scientists to improve the breeding efficiency to deliver a steady stream of cultivars that will provide yield benefits under both ideal and stressed environments. To achieve this objective in the shortest possible time, it is imperative that various crop breeding activities are integrated with appropriate new genomics technologies. In this context, the last decade has seen a remarkable rise in the generation of important genomic resources such as genome-wide markers, high-throughput genotyping assays, saturated genome maps, marker/gene-trait associations, whole-genome sequence and germplasm resequencing data. In some cases, marker/gene-trait associations are being employed in pigeonpea breeding programs to improve the valuable yield and market-preferred traits. Embracing new breeding tools like genomic selection and speed breeding is likely to improve genetic gains. Breeding high-yielding pigeonpea cultivars with key adaptation traits also calls for a renewed focus on systematic selection and utilization of targeted genetic resources. Of equal importance is to overcome the difficulties being faced by seed industry to take the new cultivars to the doorstep of farmers.

    Abstract Pigeonpea is an important food legume crop of semi‐arid tropical regions. Plateauing of pigeonpea yield has been worrying breeders for the past 6–7 decades. Serious breeding efforts made during this period resulted in various high‐yielding and disease resistant cultivars. However, the gains in pigeonpea productivity have been modest. The authors, while reviewing this situation, conclude that long generation turnover, complexity of biological traits, low selection response and overreliance upon pedigree breeding present the key bottlenecks for this situation. In this paper, some alternative breeding approaches and technologies are suggested for the genetic enhancement of yield stability and stress response of pigeonpea.
