Chickpea is a relatively new crop in the NE South Africa. High incidences of plant death were observed in an experiment that was established in 2012 in Mziniti, South Africa to assess the agronomic performance of 66 elite chickpea lines from International Crop Research Institute for Semi-Arid Tropics. Infected plants showed signs of root rot. Therefore this study aimed at investigating the cause o [...]

Genomic selection (GS) unlike marker-assisted backcrossing (MABC) predicts breeding values of lines using genome-wide marker profiling and allows selection of lines prior to field-phenotyping, thereby shortening the breeding cycle. A collection of 320 elite breeding lines was selected and phenotyped extensively for yield and yield related traits at two different locations (Delhi and Patancheru, In [...]

Chickpea is the second most important legume crop largely grown under semi-arid tropics where terminal drought is one of the major constraints for its productivity. A trait-based selection had been considered more beneficial in drought tolerance breeding to overcome the environmental influence on drought yields. Large number of traits had been suggested in literature, with less indication on their [...]

Chickpea (Cicer arietinum L.), is a multi-functional crop with important role in the diet as affordable protein source and in sustaining soil fertility through nitrogen fixation. However, its productivity in Ethiopia of 1.9 t ha-1 is lower than its potential of 5 t ha-1 under well managed conditions, partly due to soil fertility limitations. Field experiments were conducted to evaluate effectivene [...]

Terminal drought is a major constraint to chickpea productivity. Two component traits responsible for reduction in yield under drought stress include reduction in seeds size and root length/root density. QTL-seq approach, therefore, was used to identify candidate genomic regions for 100-seed weight (100SDW) and total dry root weight to total plant dry weight ratio (RTR) under rainfed conditions. G [...]

Crop domestication and subsequent diversification represent adaptations to human-built environments and offer insights into the evolutionary forces that shape phenotypic diversity. Chickpea (Cicer arietinum), a widely cultivated food legume, was domesticated in the Fertile Crescent together with several other so-called founder crops (Zohary et al., 2012). This is evidenced by the Neolithic archeol [...]
