Head smut is also an increasing problem in coastal Texas.
To speed up monitoring efforts, Prom and his colleagues evaluated 4 techniques for screening sorghum for head smut resistance using 32 isolates of the pathogen collected from different parts of Texas.
Among which the most prevalent diseases of sorghum are caused by fungal pathogens, such as leaf blight (Helminthosporium turcicum), downy mildew (Sclerospora sorghi), rust (Puccinia purpurea), head smut (Sporisorium reilianum), and anthracnose (Colletotrichum graminicolum) (Maqbool et al.
1994) developed RFLP markers (pFBT, xS 560 and xS 1294) and RAPD marker (OPG5) linked to head smut resistance genes in sorghum.
We previously developed two SSR markers (Xtxp13 and Xtxp145) tightly linked with the resistance to sorghum head smut physiological race 3, with the Xtxp13 located in sorghum chromosomes 2, and Xtxp145 located in chromosomes 6, and the recombination percentage between markers and resistant gene are 9.
In this study, we used the technologies of RAPD and SCAR to identify the molecular markers linked to resistant traits of sorghum head smut physiological race 3, and obtained two SCAR markers.
Bulked segregant analysis (BSA) was employed for identifying putative markers associated with the head smut resistance.

The result revealed that lines carrying Ht1, Ht2 and head smut QTL had resistance level and yield over donor Ent17, Ent12, lines carrying Ht1 and Ht2, and lines carrying Ht1 and head smut QTL, suggesting that marker assisted-selection strategy can be used effectively to select high yielding and resistance level in breeding materials in maize.
and head smut (HS), caused by Sphacelotheca reilana (KUhn) Clint, are two important diseases of maize (Zea mays) in China.
According to the previously reported linked-markers to resistance genes Ht1, Ht2, Ht3, HtN1 and QTLs to NLB and head smut resistance QTLs, tightly linked SSR markers falling in or nearby the reported markers were chosen from the public database of maize genome (http://www.
Plant materials and crosses: Parental inbred Ent17 with NLB resistance and parental inbred Ent12 with head smut resistance were provided by International Maize and Wheat Improvement Center (CYMMIT), parental inbred Liao3162 susceptible to both NLB and head smut were provided by Maize institute, Liaoning Academy of Agricultural Sciences, Shenyang, Liaoning Province, China.
Primer selection and PCR amplification: According to previously reported linked-markers to resistance genes Ht1, Ht2, Ht3, HtN1 and QTLs to NLB and resistance QTLs to head smut, tightly linked SSR markers falling in or nearby the reported markers were chosen from the public database of maize genome (http://www.
reilianum spores at College Station and Corpus Christi, TX to identify which lines were resistant to head smut.
