Response to mass selection for plant height and grain yield in amaranth (Amaranthus spp.)

Response to mass selection for plant height and grain yield in amaranth (Amaranthus spp.)

1987

A:PS

Two landrace accessions of amaranth, UCC192 (Amaranthus caudatus) and UCH213 (A. hypochondriacus), were used in a mass selection experiment; five per cent of the tallest and highest yielding plants in both populations were selected for three cycles. Selection gain was largest in the first cycle for both traits. Realized heritability estimates for plant height were 0.22 in the UCC192 population and 0.49 in UCH213, and 0.09 in both population for yield. The results supported earlier findings for the existence of genetic variability within amartanth landrace population. [AS]
