New Chickpea Varieties Set to Ward Off Beet Armyworm
August 28, 2009| |
The newly-bred "CRIL-7" chickpea is hoped to end the fight against the crop-damaging larval stage of the beet armyworm, said a report by the United States Department of Agriculture-Agricultural Research Service. Chickpea provides protein, fiber and other nutrients, and an important crop in semi-arid tropical countries like India. The beet armyworm is a very devastating pest in India which used to be the world leader in chickpea production in 2005.
The team of scientists led by entomologist Stephen Clement selected 42 lines from the seven generation of progenies from the cross between the wild species Cicer reticulatum which has broad insect resistance trait, with the susceptible cultivar FLIP 84-92C. The selected lines were tested in 2006-07 green house trials, and 28 to 62% of the beet armyworms that fed on the leaves died within a few days from hatching from eggs. Worms which survived were shorter and smaller. Agronomic testing will be conducted next before the lines are commercialized.
