tailieunhanh - Breeding for the salinity tolerance rice variety in Viet Nam

Presentation article this study focus on developing new rice varieties which are salt tolerant combine with high yield potentials, high quality using Molecular Markers and convensional breeding. The Saltol QTL introgresion lines were developed and selected through generations from Vietnam popular rice variety AS996 using markers assisted backrossing (MABC). After three backcross generations, the selfing generations were developed. Conventional breeding were used to select the high yield, high quality lines. Screening for salinity tolerant were carried out to evaluate all the selected lines in the salt affected field and in greenhouse. The important agronomical traits evaluations concerning to high yield and resistances to biotic and abiotic stress (salt tolerance) were applied on the BC3F3 -BC3F6 generations for breeding purpose in several areas. A promissing new salt tolerant rice line with high yield potentials, high quality were received. | Journal of Agricultural Technology 2015 Vol. 11 8 2263-2272 Available online http ISSN 1686-9141 Breeding for the Salinity Tolerance Rice Variety in Viet Nam Luu Minh Cuc 1 Phung Ton Quyen2 Luu Thi Ngoc Huyen1 and Le Huy Ham1 1.

This new variety was sent to the National Variety Trial and Testing Centre for Value-for-Cultivation-and-Use VCU and Distinctness-Uniformity-Stability DUS tests and trials at different ecological zones. Keywords AS996 MABC rice salinity tolerant Saltol. Introduction Rice is the largest foreign exchange earner among Vietnam s agricultural exports and also the main staple food for most of the country s 90 millions people. Developing adaptation rice varieties to cope with climate change and sea level rise is very important to Vietnam economy and food security it also contributes to the .
