Interrelations among factors influencing the oil content of corn

Corn samples of hand-pollinated ears from 57 F2 plants representing crosses between inbred lines and the Illinois High Oil selection were hand separated into endosperm, germ, and bran, and each fraction was analyzed for oil and protein. Germ oil and total oil were very highly correlated (r=0.97) whi...

Summary:Corn samples of hand-pollinated ears from 57 F2 plants representing crosses between inbred lines and the Illinois High Oil selection were hand separated into endosperm, germ, and bran, and each fraction was analyzed for oil and protein. Germ oil and total oil were very highly correlated (r=0.97) which indicated that analysis of the whole grain for oil was adequate to determine the amount of commercially extractable oil, and that hand dissection of kernels was not necessary. The correlation between the percentage oil in separated germ and the percentage oil in separated endosperm was also high (r=0.73). Germ oil in total kernel was highly correlated with proportion of germ in the kernel (r=0.86) and with percentage oil in the separated germ (r=0.48). Size of kernel had relatively little influence on composition in the samples studied.
