The Genotypic and Phenotypic Basis of Chickpea (Cicer arietinum L.) Cultivars for Irrigation-Based Production in Ethiopia uri icon

abstract

  • Development of irrigation-based chickpea production is considered the most important alternative approach incombating climate change and maximizing productivity, especially in moisture-stress areas and in areas wherewater and land for irrigation is available. In central Ethiopia, where production of chickpea (especially Kabulitype) is becoming an important part of agriculture, although many superior varieties (both desi and Kabuli types)are available, they have been evaluated and released based on rainfed production. Hence, there is an urgent needfor evaluation of varieties suited for irrigation-based production. Towards this goal, during the 2012/13 growingseason, 14 Kabuli genotypes (previously introduced) and 24 desi genotypes (nurseries obtained from ICRISAT)were evaluated independently at three and one locations respectively (Kabuli at Debre Zeit, Ambo and Werer;desi at Debre Zeit) for production adaptation under irrigation. The parameters evaluated were date of maturity,100-seed weight and yield. Overall, while most Kabuli genotypes showed high adaptability to irrigation-basedproduction at all locations, four Kabuli genotypes (X96TH-52-14/2000 = 106.7DAS, FLIP-02-39C = 107DAS,X98TH-51-1-3 = 107.9DAS and ICCV-07313 = 107DAS) were found to be earlier in maturity; two genotypes(ICCV-07313 = 42.5 g and ICCV-04305 = 37.8 g) were identified as having high 100-seed weight and onegenotype (ICCV-05309 = 3228.8 kg/ha or 32 quintals/ha) out yielded all genotypes across locations. The resultof combined analysis indicated five promising genotypes showing more than 20 kg/ha yield on average. All desivarieties showed maturity dates of under four months; six genotypes showed higher 100-seed weight and eightgenotypes showed promising yield responses (> 2000 kg/ha). From these preliminary results, it can be deducedthat irrigation can play a significantly complementary role to the rainfed system, provided the genetics bymanagement is optimized through research and innovation
