Genetics of lodging resistance in chickpea ( Cicer arietinum L)

摘要: Lodging (stem bending) is a serious problem causing severe yield reduction, poor grain filling, lower harvest index and deterioration in quality of chickpea environments characterized by favorable temperatures soil moisture conditions. Breeding for lodging resistance also required to improving adaptation better agronomy achieving breakthrough its productivity stability production. However, no information available on genetics chickpea. The objectives were (i) characterize the newly identified resistant germplasm FLIP07-183C important plant characteristics (ii) study inheritance an inter-varietal cross between susceptible high yielding desi cultivar Pusa 362 kabuli FLIP07-183C. was tall, erect, late flowering genotype with semi-determinate stem growth habit large seeds. It contained higher lignin content than cultivar, 362. found be dominant over susceptibility. segregation patterns F2 F3 362 × FLIP07-183C showed that two non-allelic genes duplicate gene action controlled are designated as Sb1/sb1 Sb2/sb2. homozygous recessive both alleles (sb1sb1sb2sb2) produced phenotype. utilization has major impact breeding cool climate, fertility irrigated environments.
