Identification of quantitative trait loci associated with boiled seed hardness in soybean.

ABSTRACT: Boiled seed hardness is an important factor in the processing of soybean food products such as nimame and natto. Little information is available on the genetic basis for boiled seed hardness, despite the wide variation in this trait. DNA markers linked to the gene controlling this trait should be useful in soybean breeding programs because of the difficulty of its evaluation. In this report, quantitative trait locus (QTL) analysis was performed to reveal the genetic factors associated with boiled seed hardness using a recombinant inbred line population developed from a cross between two Japanese cultivars, 'Natto-shoryu' and 'Hyoukei-kuro 3', which differ largely in boiled seed hardness, which in 'Natto-shoryu' is about twice that of 'Hyoukei-kuro 3'. Two significantly stable QTLs, qHbs3-1
