Research Abstract

The seed coat of soybean cracks under field conditions. Two QTLs, cr1(molecular linkage group(MLG) D1b and cr2 MLG M) were identified. The cr1 was not associated with seed size or maturity in near-isogenic lines(NILs). Therefore, markers around the QTL may be useful for breeding to reduce cracking symptoms without altering seed size or maturity. In contrast, two QTLs for net-like cracking(ncr1 and ncr2) were identified in MLG C1 with a distance of about 62 cM. These results suggest that genetic control of seed coat cracking occurring under field conditions was different from net-like cracking. Microarray of the NILs revealed genes highly expressed in the tolerant NIL(Gma. 26856, Gma. 16827, Gma. 173) and genes highly expressed in the sensitive NIL(Gma. 48109 and Gma. 49562).
