A simple and a full-sib reciprocal recurrent selection programmes were conducted on sweet corn varieties Manis Madu and Bakti-1 at the research farm Universiti Pertanian Malaysia. The objectives of the study were to compare the response to the two selection procedures and to estimate heritability of some important characters in the two populations. The presence of higher genetic variance in Bakti-1 S1 population (B1S1) compared to that of Manis Madu (MMS1) showed that B1S1 possessed higher genetic variability than MMS1. Broad-sense heritability estimates for the characters studied were moderate to high (42.6 percent to 65.7 percent) in the selfed progeny populations but were low to moderate (20.0 percent to 49.2 percent) in the crossed progeny populations. After one cycle of selection simple recurrent selection was found more effective in increasing yield in both populations. Simple recurrent selection has increased fresh year yield in Bakti-1 and Manis Madu by 16.7 percent and 10.2 percent respectively while full-sib reciprocal recurrent selection has increased it in Bakti-1 by 5.9 percent but decreased it in Manis Madu by 6.4 percent

Abstract

A simple and a full-sib reciprocal recurrent selection programmes were conducted on sweet corn varieties Manis Madu and Bakti-1 at the research farm Universiti Pertanian Malaysia. The objectives of the study were to compare the response to the two selection procedures and to estimate heritability of some important characters in the two populations. The presence of higher genetic variance in Bakti-1 S1 population (B1S1) compared to that of Manis Madu (MMS1) showed that B1S1 possessed higher genetic variability than MMS1. Broad-sense heritability estimates for the characters studied were moderate to high (42.6 percent to 65.7 percent) in the selfed progeny populations but were low to moderate (20.0 percent to 49.2 percent) in the crossed progeny populations. After one cycle of selection simple recurrent selection was found more effective in increasing yield in both populations. Simple recurrent selection has increased fresh year yield in Bakti-1 and Manis Madu by 16.7 percent and 10.2 percent respectively while full-sib reciprocal recurrent selection has increased it in Bakti-1 by 5.9 percent but decreased it in Manis Madu by 6.4 percent
