CORRELATED RESPONSE TO SELECTION FOR YIELD COMPONENTS IN SEGREGATING POPULATIONS OF RICE (ORY2'A SATIVA L.)

Abstract

Correlated response to selection was worked out for number of tillers/plant, panicle length. number of grains/panicle and 1000 grain weight in 280 F3 progenies of the cross UPR 83-341Sita during Khanf, 1993 in random and biased (on the basis of grain yield/plant) populations selected from four different plant spacings viz., 15 x 10 em, 20 x 10 em, 20 x 15 em and 20 x 20 em during Khanf, 1992. Though no definite trend could be established, random selection by and large, resulted in positive correlated response for different yield components. The correlated response varied from character to character in the plant progenies selected on the basis of grain yield alone (biased selection)
