Analysis of biochemical constitution of new germplasm in sweet corn
--Liu, Y; Zeng, M and Ye, S

The new germplasms of the sweet corn which were transferred and bred were used as experimental materials. The biochemical constitution, the heterotic rate and genetic control were studied. The results showed: 1) the new germplasms have high nutritive value and taste quality and were similar to the progenitor type in each biochemical constitution; 2) the heterotic rates were negative on most quality characters, but it is evidently different from the growth vigour character; 3) the external characters and the content of sugar were controlled by a pair of recessive genes in the normal sweet, brittle sweet and supersweet corn (Tables 1-3).
