| Improvement of non restorer lines (B-line) of sweet sorghum was carried out at the National Corn and Sorghum Research Center, Pakchong district, Nakhonratchasima province during 2005-2009 for 10 seasons, aimed to improve their yield components by backcrossing method for 3 generations and followed by 4 generations of pedigree selection. For pedigree selection procedure, line selection was compared to family selection method. In late rainy season 2009, it was found that 40 non restorer lines of sweet sorghum were selected from the line selection method. They had 54-62 days to flowering, 136-298 cm of plant height, 12-14 leaves per plant, 18-30 cm of panicle length, 10.1-15.8 percent brix of sweetness, 17-22 mm of stem diameter, 2.0-3.0 leaf diseases score,... |

| “Maejo 2” is a new variety of glutinous rice with desirable aroma, lacking photoperiod sensitivity and exhibiting a semi-dwarf stature. Glutinous rice Maejo 2 was improved from the recurrent non-glutinous rice parent, Pathum Thani 1 (WxWx), which has desirable aroma, lacks photoperiod sensitivity and has a semi-dwarf stature. Pathum Thani 1 was crossed with a glutinous rice (wxwx) donor parent, RD6 to initiate a backcross breeding program. Molecular markers for the wx (glutinous, recessive) or Wx (normal, dominant) alleles were used to identify progeny that inherited the desired wx allele in heterozygous individuals that don’t express the glutinous phenotype. Thus, each BCnF1 generation, F1 progeny with the of backcrossing in this way, the BC4F1 plants... |
