Comprehensive Analysis of Effect of Submergence on Rice Grain Quality

Journal Title: Current Investigations in Agriculture and Current Research - Year 2018, Vol 5, Issue 5

Abstract

Flash flooding is one of the major problems in rice growing areas of South and Southeast Asia and it severely limits rice yield in these areas. This experiment was performed to check cultivated varieties with resistance against submergence and check best varieties which give better grain quality after affected by submergence. Chenab Basmati one of the cultivated varieties proved best performer in this experiment and is recommended for cultivation in areas affected by flood in PakistanRice is one of the important crops in cereals. Rice is staple food of 50% population all around the world. Its higher production and good taste are two main parameters for many breeding projects but, in contrary to disease and insect resistance, grain yield and quality are both managed by quantitative trait loci (QTLs) highlighting continuous phenotypic difference in rice offspring [1]. So, it is hard for breeders to upgrade rice grain yield and quality using conventional techniques, due to a lack of distinct phenotypic segregation in the offspring. As rice grain quality is an endosperm characteristic, its heredity can be more complex because the genetic expression of an endosperm trait in cereal seeds is conditioned not only by the triploid endosperm genotype, but also by the diploid maternal genotype and any additional possible cytoplasmic differences [2-4]. Quality of rice grain comprises of cooking, milling, appearance and nutritional qualities. But appearance and cooking quality is mostly focused by people [5]. The appearance quality is often judged in China by the percentage of grain with a white core and a square of white core. Climate change is enhancing submergence stress, which is one of the main hurdles in increasing rice yield in rice growing areas of world. The most common and devastating type of flooding is short-time inundation (up to 2 weeks), also known as flash floods. 20 million hectare of rice growing area is affected by this kind of flooding in Asia (excepted China) as well as many lowland areas of Africa [6-10]. Moreover, due to disastrous effects from climate change, these seasonal flash floods are adversely unpredictable and can occur at any growth period of the rice crop [11].
