Effectiveness of individual plant selection in early generations of bread wheat.

摘要

Reliability of individual plant selection was tested for grain yield, plant height, effective tillers, total DM, grain/spike, kernel weight and harvest index in 5 F2 populations of bread wheat grown during rabi 1992-93. Plants were selected for eachof the 7 characters in positive and negative directions in F2 plants and the selection response was determined in F3 plants. Significant inter-generation correlation coefficients and moderate to high realized heritability estimates were observed in 3 ofthe populations for kernel weight and kernel weight, indicating that individual plant selection for plant height and for kernel weight was effective.
