Association of grain yield and some other characters under four nitrogen levels in triticale



Association of grain yield and some other characters under four nitrogen levels in triticale



Crop Improvement 13(2): 158-163



Correlation and path coefficient analysis for grain yield and other quantitative traits were studied in triticale (X Triticosecale) separately at each of the four nitrogen levels (N0, N60, N120 and N180 k/ha). Grain yield exhibited high positive correlation with effective tillers and grains per spike all the N-level and with 1000-grain weight at N0 and N60 levels. Negative association of grain yield was observed with days to heading at all the N-levels. Path analysis revealed positive direct effect of grains per spike, 1000-grain weight, effective tillers and days to heading on grain yield at the different nitrogen levels. However, some indirect effects either enhanced or nullified the direct effects of different characters on grain yield. The implications of these results in triticale breeding have been discussed.
