Effect of mass selection and full-sib recurrent selection on the yield of Tainan-white maize population



Effect of mass selection and full-sib recurrent selection on the yield of Tainan-white maize population



Journal of the Agricultural Association of China 2(2): 130-139, April



Six cycles of mass selection, two cycles of full-sib recurrent selection, and the original Tainan-white (TNW) maize population were available in this study. All the material planted at Wufeng and Lunpei in the fall of 1997. Ear height, ear length and fresh weight were the major seleceted traits in this experiment. The results indicated that no significant response was detected on the yield of Taichung TNW population followed by six cycles of mass selection. However, the average yield of Taichung TNW population were significantly improved by two cycles of full-sib recurrent selection. Across the two locations, the response of fresh weight of ear with husk and ear fresh weight to full-sib recurrent selection from C0 to C2 increased 19.01% and 16.79%, respectively. It showed that the efficiency of population improvement by the full-sib recurrent selection is better than that of mass selection on yield.
