Abstract
An experiment carried out to evaluate the performance of local maize variety compared to the modern variety. Treatment comprised three modern varieties i.e. Plough-201, Plough-202 and Suvra; and five local landraces i.e. Red, Purple, White, Yellow and Black. Local landraces were sown two times, 5 March 2015 (early) and 10 March 2015 (Late). Results revealed that the modern varieties produced tassel and silk 11. 33 and 20.50 days earlier, respectively along with 28.17 days earlier harvesting days compared to the local ones. The local landraces were bit longer plants (5.02 cm) than the modern varieties. The local landraces had three more leaves per plant (17) compared to that of the modern ones. The stem base of the modern varieties was 20% thicker (9.11 cm stem base circumference) compared to the local landraces. The modern varieties produced cobs at the 7th nodes whereas those of the local varieties almost at the top of the plants (12th nodes). Delayed sowing time of the local landraces resulted in the delayed tasseling and harvesting days by 11 and 23 days, respectively. The variety yellow grained had the longest tasseling days (69 days) whereas the white grained variety the shortest (62 days). The white grained variety had the longest silking days (87.50 days) while the red and black grained the shortest (78.50 days). The yellow grained variety sown in delay had the longest tasseling days (78 days) while red, black and purple sown early had the lowest tasseling days (58 days). The purple grained variety at both the sowing dates and; yellow and white at the late sowing dates produced silk in delay (87-88 days) while others in 71-81 days. The longest variety was the yellow grained showing 213 cm whereas the white grained variety was the shortest (170 cm). The variety white grained had 1.45 to almost three more leaves (17.40 per plant) than others. The thickest stem base circumference was obtained in the black grained one (8.40 cm) and the lowest in the red grained one (6.50 cm). The information derived from this study may be a good source of new allelic diversity that could at least be used for developing different important elite maize materials especially the ones to be produced for fodder purposes.
