Figure 3 -. Amplification of EST-PCR primer pairs in the parents and ND646. a-d. Markers CINAU 91, CINAU 502, CINAU 506 and CINAU 511, respectively. 1-4 were CS, WJ28-1, ND646 and Ningchun 4, respectively; 5-20 were the amplification of marker CINAU 91 in 16 individual plants of ND646; M was a DNA marker with a molecular weight of 100, 250, 500, 750, 1000 and 2000 bp. Arrows showed specific banding of 6HcS and 6HcL chromosomes.
