Growing rice in dry season in the upper northern region is depend upon two significant factors including, the varietal acceptance which high yield, disease and insect resistance and high market demand. The program on research and development of irrigated rice in the upper northern region has carried out the project and developed the new rice promising line, namely PRE02008-CRI-18-2-1-1 which is glutinous rice and insensitive to photoperiod. This line was obtained from single cross, PRE93001-8-1-2-1-1/ PRE1. The average yield is 854 kg/rai which are 2 and 4 % greater than SPT1 and RD14,respectively whereas the maximum yield potential reaches 984 kg/rai in wet season and 1,110 kg/rai in dry season at Phrae and Chiangrai province, respectively. This line is... |
