RELATIONSHIP OF PLANT HEIGHT, DAYS TO FLOWERING AND MATURITY TO GRAIN YIELD IN SHORT-DURATION DETERMINATE PIGEONPEA

Published on

Generally, pigeonpeas of determinate growth habit and short duration are of short stature
compared to the traditional indeterminate types. The association of plant height, days to
flowering and maturity, and grain yield were assessed among 100 determinate
short-duration pigeonpea lines derived from different genetic backgrounds. Plant height
and days to maturity showed strong positive genotypic and phenotypic correlation with
grain yield. Days to flowering was positively correlated with days to maturity and plant
height. Tall determinate plants appeared to be promising for grain yield. However, the
existence of a positive association between plant height and growth duration may cause
difficulties in the selection of early flowering tall plants. Nonetheless, high selection
pressure for medium to tall determinate plants among early-flowering segregates mayyield
more productive genotypes.
