“…In Sudan, chickpea is the third most economically important food legume crop after faba bean and cowpea, as a cash crop that generates income for farmers and rural communities, and as a significant source of protein for Sudanese people (Mohamed et al, 2015). It is traditionally grown as a winter crop in River Nile State, northern Sudan.…”

“…The productivity in Sudan is generally low (1.75 t ha -1 ) (FAO, 2018), partly due to the use of inferior seeds purchased from local markets or imported from neighboring countries. Chickpea fields planted in November each year (early planting) are susceptible to high virus and wilt/root rot infections (Mohamed et al, 2015;2018). Late planted crops (December/early January) showed low amounts of virus and root rot infections, but are more exposed to heat than early sown crops (Abdelmagid Adlan Hamed, personal communication), and this leads to high amounts of empty pods.…”

In Sudan yellowing viruses are key production constraints in pulse crops. Field surveys were carried out to identify luteovirids affecting chickpea crops in the major production regions (Gezira Scheme and River Nile State). A total of 415 chickpea plant samples with yellowing and stunting symptoms were collected during the 2013, 2015 and 2018 growing seasons. Serological results (Tissue-blot immunoassays) showed that Luteoviridae and Chickpea chlorotic dwarf virus (CpCDV, genus Mastrevirus, family Geminiviridae) were the most common viruses, with rare infections with Faba bean necrotic yellows virus (FBNYV, genus Nanovirus, family Nanoviridae). Some samples reacted only with a broad-spectrum luteovirid monoclonal antibody (5G4-MAb), and others showed cross reactions between the specific monoclonal antibodies, suggesting the occurrence of new luteovirid variants. Serological results were confirmed by amplification with reverse transcription-polymerase chain reaction (RT-PCR) and sequencing of the partial coat protein gene. Molecular analyses provided a basic, sufficient and reliable characterization for four viruses affecting chickpea that belong to Polerovirus (family Luteoviridae). These were Cucurbit aphid-borne yellows virus (CABYV), Pepper vein yellows virus (PeVYV), Pepo aphid-borne yellows virus (PABYV) and Cotton leafroll dwarf virus (CLRDV), that shared high similarity with the type sequences. Phylogenetic analyses also revealed high similarity to luteovirid species. This study has established reliable, rapid and sensitive molecular tools for the detection of luteovirid species.

“…Since kabuli-types are indigenous to Mediterranean areas, we presume that some genotypes may have a degree of adaptation to low temperature. Genotypic variability amongst the desi and kabuli cultivars in Sudan has been reported recently [4].…”

“…Cultivars grown in Sudan are either local (desi) type (called "Jabel Marra") characterized by smaller, angular, light brown (pigmented) seeds and early mature or introduced Mediterranean (kabuli) type with larger, rounded seeds which lack pigmentation which is late mature cultivar such as NEC 2491 (locally called "Shendi"). The second cultivar has been released and recommended to be grown in Northern Sudan due to their vigorous growth and high yield potentiality [4]. Since kabuli-types are indigenous to Mediterranean areas, we presume that some genotypes may have a degree of adaptation to low temperature.…”

“…In Sudan, chickpea is traditionally grown as a winter crop in the northern part, however, its production has expanded recently to the central clay plain of central Sudan [4]. The growing season is restricted to a short period of time by the high temperatures prevailing at the beginning and at the end of the season [4]. The chickpea yields in Sudan vary from 0.83 to 2.8 t/ha, depending on weather conditions [5].…”

A laboratory experiment was carried out to determine the effect of temperature on germination and early seedling establishment and to study the variation among thermal time model parameters for two contrasting chickpea cultivars. Seeds were subjected to six constant temperatures from 10˚C to 35˚C. A complete randomized design was used with four replications. Analysis of variance showed significant differences (p < 0.05) among all characters studied. The final germination percentage of both cultivars significantly (p < 0.05) increased with increasing temperature up to 25˚C, and thereafter there was a sharp decrease in final germination at super optimal temperatures (30˚C and 35˚C). Desi type cultivar (small seeded) locally called "Jabel Marra" significantly (p < 0.05) exhibited higher final germination percentage and germination rate compared with the smaller seeded kabui type cultivar "Shendi" at all temperatures. The median (θT(50)) of the thermal time was significantly (p < 0.05) different between the two chickpea cultivars. The large seeded cultivars (Shendi) recorded significantly (p < 0.01) higher median thermal time than the small seeded cultivars (Jabel Marra). The results also revealed significant (p < 0.01) differences between the two cultivars on the other parameters of thermal time model. On the other hand, the small seeded cultivar (Jabel Marra) scored lower total dry matter and temperature tolerance index (TTI) compared with the large seeded cultivar (Shendi) at all temperatures studied.

Chickpea (Cicer arietinum L.) is one of the most important legume crops, mainly grown in tropical and subtropical climates. Evaluation of yield performance in crops under multienvironments is applied to verify the stability of cultivars. The aim of this study is to apply the analytical and experimental models to identify the high‐yielding and stable genotypes of chickpea under dryland conditions. Sixteen chickpea lines and two control cultivars were cultivated in randomized complete block design with three replications in four regions at three cropping seasons (2016–2019). Third type of biplot showed that G4, G15, G10, G9, and G18 were highly productive and widely stable. A selection index based on different weights of seed yield and WAASB stability indicated genotypes G7, G9, G15, G4, G16, G18, G12, and G5 were high yielding and stable. Data mining showed that high rainfall in winter can lead to high yield. Partial least squares regression (PLSR) analysis indicated that rainfall in autumn and spring and low temperature in all of the three seasons involved in genotype by environment interaction (GEI). Factorial regression (FR) also indicated that temperature during spring and winter plays an important role in GEI. In conclusion, based on all experimental approaches, G15, G16, and G5 were stable and high‐yielding genotypes. The PLSR biplot indicated G15 was the genotype that less affected by high temperature in three seasons and lack of rainfall in spring and autumn, it can be used in cultivar introduction processes for dryland cultivation.
