Evaluation of genetic effect on physiochemical properties changes of Wx near isogenic lines of Y58S in rice

The Wx gene primarily influences the physiochemical properties changes of rice (Oryza sativa L.) To improve the grain qualities of the cv. Y58S with low amylose content (AC) value, the genetic effect of Wx gene was explored on quality traits. With the BC3F2 genetic population of Y58S line associated...
