Results of selection and trial production of some high quality rice varieties in Muong Tac field of Phu Yen district, Son La province
The selection and expansion for production of new, high quality rice varieties were aimed to enhance the implementation of economic value, effectively exploiting the advantages of Muong Tac field, Phu Yen District, Son La province. 09 new high quality varieties of HT6, HT18, BM125, HT13, HT9, XT27, LT25, BT09, Glutinous rice N98, BT7, selected and created by Vietnam Academy of Agricultural Sciences as commodity rice products, were tested and selected breeding towards developing rice products: HT6, HT18, BM125, HT13, HT9, XT27, LT25, BT09, Glutinous rice N98 and BT7 was used as the controls. From the selection results in the spring and autumn crops in 2011, two promising varieties (HT6, XT27) were identified as having rather good resistance to pests, with 20% higher yield than the control. Conducting tests on two promising rice varieties (HT6, XT27) and BT7 was used as the controls in the spring 2012, the results show that XT27 and HT6 gave higher yield than the control BT7 from 11.2 to 11.9 quintals/ha and higher economic value from 11.2 to 11.4%.
