| This research aimed to access farmer participatory breeding in selecting the local upland rice varieties for desirable agronomic traits, good cooking and eating grain characteristics. The research carried out in the land reform area of amphoes Mueang, Lamae, Thung Tako in Chumphon province. The experiment comprised 12 upland rice varieties, 11 experimental lines and 1 standard check, by using the Randomized Complete Block design with 4 replications. Results indicated that farmers had selected Samdeaun, Phukhaotong, Nahngkruan, Lebnok and Dawkkham varieties for desirable agronomic traits with reasonable uniform panicle, good tillering ability, long panicle, many secondary branches, large and heavy grains. For cooking and eating qualities, they selected... |

| “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... |
