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

Published on

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)
