Consequence of Wide Crossing in Chickpea Nalini Mallikarjuna1, Deepak Jadhav, Heather Clarke2, Clarice Coyne3 3and Fred Muehlbauer (1. Utilization of wild Cicer species has become essential as a series of evolutionary bottlenecks have narrowed the genetic base of chickpea, thus making it susceptible to a range of diseases and pests. Future studies will examine how ambient light, temperature, and humidity may be influencing the efficiency of crossing chickpea plants. In the F ,48 (1993) succeeded in crossing chickpea with C. echino- 5 5 uniform and promising progenies from the reticulatum cross and 87 spermum. Gather all your mise en place, (everything in it’s place) before making the hummus. Therefore, a new approach is needed to utilise the more distantly related … tissue culture techniques are now available for chickpea and pigeonpea (Mallikarjuna 1998), which can be used to save aborting hybrid embryos. • Types of Chickpea. This makes cooking more enjoyable because you have all your ingredients ready for the process. One reason is that chickpea has no wild relatives within its own species, C. arietnum, and only two annual wild species are readily hybridised with chickpea using conventional crossing techniques. Chickpea crossing techniques are tedious. Tissue culture techniques play an important role in the utilization of wild Cicer species for the improvement- of cultivated chickpea. 24. In chickpea, a transcript map with 126 genic molecular markers, including 53 CAPS-SNPs, 55 EST-SSRs and 18 CISR loci has been developed (Gujaria et al., 2011). Therefore, a new approach is needed to utilise the more distantly related species in the secondary and tertiary genepools. Hybridization or crossing technique in Pigeon pea or arhar Cajanus cajan - Duration: 3 ... S3 • E5 CHICKPEA | How Does it Grow?
