Downy mildew (DM), Peronosclerospora sorghi (Weston and Uppal) C.G. Shaw, is one of the most destructive diseases of maize (Zea mays L.) in Thailand. Understanding the genetic basis of downy mildew resistance could increase the efficiency of breeding for disease resistant germplasm. The objectives of this study were to use the SSR primers associated with QTLs which produced major effects, umc1072 found in chromosome bin 5.07, and bnlg1867 found in chromosome bin 6.01 used to transfer resistance alleles to susceptible lines by marker-assisted selection. A backcross method was carried out in this research. Agron18 and Nei452006 were susceptible lines used as recurrent parent, Nei9008 was resistant line used as donor parent. The results indicated that... Palavras-chave: Maize; Downy mildew disease; SSR primers; Marker-assisted selection; ข้าวโพด; โรคราน้ำค้าง; การปรับปรุงพันธุ์; พันธุ์แท้; ความต้านทานโรค. Ano: 2010 URL: http://anchan.lib.ku.ac.th/agnet/handle/001/4661 การประเมินข้าวโพดลูกผสมฝักดกและฝักเดี่ยวที่อัตราปลูก 2 ระดับ Thai Agricultural Sansern Jampatong; Chatpong Balla; Prapon Boonrumpun; Anucha Mekarun; Athiwat Songpinich. Objective of this preliminary research was to study the effect of different plant densities with prolific and single-ear maize hybrids on yield and other characters in maize. The experiment was a split-plot arrangement in randomized complete block design with three replications. Main-plot consisted of two plant densities: 7,111 and 10,666 plants/rai, respectively. Sub-plot consisted of 30 hybrids: 13 experimental prolific, 12 experimental single- ear and 5 commercial single-ear hybrids, respectively. The experiment was conducted at National Corn and Sorghum Research Center in 2009. The results indicated that experimental prolific hybrids out-yielded single-ear hybrids at low plant density but they were lower yielding than commercial single-ear hybrids...
