INHERITANCE OF GRAIN SIZE AND SHAPE IN RICE (ORYZA SATIVA)

Published on

Inheritance of grain length, breadth and shape were studied in three crosses, viz. Pankaj x
Badsahbhog; S 214 x Mahsuri and S 214 x S 260. The characters were largely controlled by
polygene., although evidence ofmajorgenes governing the traits in some crosses were also
observed. Transgressive segregation for the chuacters was observed in two crosses.
 

Keywords: Grain length, breadth and shape, polygenes, major genes, transgressive segregation.
