Six new provitamin A
hybrids (LY1001-14,
LY1001-22 and LY1001-23,) and synthetic maize varieties (PVASYN13, PVASYN9 and
PVASYN7) were tested for their agronomic performance and compared to a locally
adapted improved open pollinated variety (SAMARU) in the central and western
conditions of DRC. A randomized complete block experiment with four
replications was used. Following data were collected: 50% male and female
flowering, plant and ear aspect, diseases incidence, plant height, ear aspect,
ear rot and yield. The results showed non-significant differences (p > 0.05) in disease incidence and
ears rot. Significant differences were observed (p < 0.05) for number of days to 50% of male and female flowering,
anthesis-silking interval, plant height, plant aspect, ear aspect, and yield.
For yield, two hybrids (LY100-14 and LY1001-22) respectively out-yielded local
check by 71% and 56% while one synthetic (PVASYN 9) out-yielded the local check
by 31% and the two others were comparable to the local check. Thus the hybrids
(LY100-14 and LY1001-22) and synthetic varieties (PVASYN 9 and PVASYN13) are
ready to be recommended for release to contribute to better production and
nutrition for vulnerable people.
