Inheritance of height and association among height, yield and yield components in wheat

Abstract

To determine the mode of inheritance of the semidwarfness trait in wheat and the genotypic relationship of this character to grain yield, number of spikes per plant, number of spikelets per spike, and date of maturity, I studied all of these traits and their interactions in nine wheat hybrids between three normal height varieties, Napo 6 3 , Crespo 63 and Bonza 6 3 , and three semidwarf varieties, Sonora 64, Son 64- 6 / 3 59- Measurements were made on spaced plants of the parents and 's in 1965 and of the parents and at the Santa Catalina Experimental Station near Quito, Ecuador.
