Última การพัฒนาสายพันธุ์อินเบรดข้าวโพดที่มีทริปโตแฟนสูงเนื่องจากยีน opaque-2 Thai Agricultural Wararat Narongwongwattana; Choosak Jompuk; Somsak Apisitwanich; Peeranuch Jompuk; Surapol Chowchong. Quality protein maize (QPM) contains the opaque-2 gene for twice tryptophan content along with modifying genes for kernel vitreousness. The QPM hybrid needs the inbred lines containing with opaque-2 gene. Therefore, the objectives of this study were to improve the corn inbred lines with high tryptophan by the opaque-2 gene that detected by molecular marker, and to estimate combing ability of these inbred lines for the yield. Eight lines of BC1S5 containing with opaque-2 gene detected by phi057 were used in the experiment. Tryptophan content in the endosperm of 8 selected lines and 28 of their diallel hybrids were analyzed using glyoxylic method. The yield trial experiment was conducted in randomized complete block design with 4 replications. The plot size...

Crosses were made between waxy corn and quality protein corn as female and male parents, respectively. In segregating progenies of two crosses, Kwi no.1 x PopII no.53 and Kwi no.9 x PopII no.53, selfing and backcrossing methods were used and then marker-assisted selection of opaque-2 gene (o2o2) by phi057 and umc1066 and of waxy (wxwx) by phi022 and phi061 were applied to obtain the opaque-waxy corn (o2o2wxwx). For the first step of MAS, phi057 and umc1066 were employed to detect the opaque-2 gene (o2o2) in both of BC1S1 and S1 generations. The genotypic ratio of opaque-2 gene (O2O2:O2o2:o2o2) was 37:46:31 for BC1S1 and 42:146:42 for S1 from the cross of Kwi no.1 x PopII no.53 while it was 41:51:41 for BC1S1 and 41:169:35 for S1 from the cross of Kwi no.9...

Nitrogen use efficiency was evaluated in 27 genotypes of waxy corn to utilize as germplasm in breeding program for sustainable agriculture. Yield, yield components and agronomic traits analyzed similarity coefficient by Squared Euclidean and cluster analysis by Ward’s method could separate genotypes into 4 groups depending on ear size, plant height and flowering date. The large ear group gave yield higher than that of the small ear group and showed high value of low nitrogen tolerant index (LNTI) and nitrogen use efficiency (NUE). The genotypes, namely BW, PEK and SLKM showed high NUE, high yield in high nitrogen condition (HN) and low yield in low nitrogen condition (LN). WPP, BW and NSW genotypes showed high value of LNTI, and high yield in both low and...

Split-split plot design in randomize complete block (RCB) was conducted including 3 main plots as the types of fertilizer (chicken and cow manures and chemical fertilizer), 3 sub-plots as the rates of fertilizer (by 0, 500, 1000 kg/rai for organic manure and by 0, 25 and 50 kg/rai for chemical fertilizer), 3 sub-sub plot as sweet corn varieties (Insee 2, Sugar 75, and KSSC 604) The experiments were conducted 4 planting dates (2 planting dates by 2 seasons). The results showed that four planting dates were significant differences for both yield and quality of sweet corn. On the other hand, there were not significant differences between the application of organic manures and chemical fertilizer. But, rates of fertilizer application were significant for...
