“…For example, the Wx locus on chromosome 6 plays major roles in specifying AC and GC plus a minor role in GT (97,98), and the Alk locus, tightly linked to Wx, has a major effect on GT (98,99). For appearance quality traits, grain length is mostly controlled by the GS3 locus on chromosome 3, and grain width is largely conditioned by GS5 on chromosome 5 (100).…”

This contribution is part of the special series of Inaugural Articles by members of the National Academy of Sciences elected on May 1, 2007.From a global viewpoint, a number of challenges need to be met for sustainable rice production: (i) increasingly severe occurrence of insects and diseases and indiscriminate pesticide applications; (ii) high pressure for yield increase and overuse of fertilizers; (iii) water shortage and increasingly frequent occurrence of drought; and (iv) extensive cultivation in marginal lands. A combination of approaches based on the recent advances in genomic research has been formulated to address these challenges, with the long-term goal to develop rice cultivars referred to as Green Super Rice. On the premise of continued yield increase and quality improvement, Green Super Rice should possess resistances to multiple insects and diseases, high nutrient efficiency, and drought resistance, promising to greatly reduce the consumption of pesticides, chemical fertilizers, and water. Large efforts have been focused on identifying germplasms and discovering genes for resistance to diseases and insects, N-and P-use efficiency, drought resistance, grain quality, and yield. The approaches adopted include screening of germplasm collections and mutant libraries, gene discovery and identification, microarray analysis of differentially regulated genes under stressed conditions, and functional test of candidate genes by transgenic analysis. Genes for almost all of the traits have now been isolated in a global perspective and are gradually incorporated into genetic backgrounds of elite cultivars by molecular marker-assisted selection or transformation. It is anticipated that such strategies and efforts would eventually lead to the development of Green Super Rice.genomics ͉ rice genetic improvement ͉ sustainable agriculture

“…As it showed a large amount of transgressive segregants, so two parents probably contain diverse set of alleles or some epistatic interaction is controlling the amylose contain. A major QTL for amylose contain, amy6, which explain more than 70% of the total variation , He et al, 1999, Tan et al, 1999, Septiningsh et al, 2003 is located in between RM190 and RM253. This locus is also assigned as waxy (wx) locus of rice.…”

“…Occurrence of chalky grains in rice substantially lowers the grade of grain quality and thus market value (He et al, 1999;Tan et al, 2000;Patindol and Wang, 2003;Cheng et al, 2005;Fitzgerald and Resurreccion, 2009;Ishimaru et al, 2009). Formation of chalky grain is enhanced by a high temperature during the ripening period, which is recently occurring more frequently due to global warming (Lin et al, 2005;Wakamatsu et al, 2007;Tsukaguchi and Iida, 2008;Lin et al, 2010).…”

“…Many studies have been conducted about chalky grains. However, most of them were carried out for understanding the mechanism underlying the high-temperature-induced grain chalkiness (Patindol and Wang, 2003;Cheng et al, 2005;Lin et al, 2005;Lin et al, 2010), or genetic analysis (He et al, 1999;Tan et al, 2000).…”
