Abstract

In order to evaluate the performance of improved maize genotypes, an experiment was conducted at Medebay zana and Laelay Adiabo district of North western of Tigray, Ethiopia, during 2014 and 2015 main cropping season. The experiment was laid out in a randomized complete block design with three replications. The data were recorded on plant height, ear height, number of ears/plot, plant and ear height, days to 50% anthesis, silking, maturity, grain yield and 1000 grain weight. All varieties showed significant differences with each other for all the traits studied in most environments but incase of genotype by environment combined data revealed most of the traits gave nonsignificant result and indicated better to focus and recommend on the stable genotypes across the environments. Variety Gibe-2 and Gibe-1 had the top two highest grain yield of 5114.15 kg ha-1 and 4964.96 kg ha-1. Melkasa-6 was the early maturing variety as compared with standard checks of melkasa-2 and the remained varieties. The highest plant height and ear placement of 237.28, 120.80, respectively cm was noted in variety Gibe-1. This variety may be susceptible to lodging. These varieties had a wide genetic background, thus showing grain yield ranges from 1748 to 5114 kg ha-1. So, generally maize variety of Gibe-1 and Gibe-2 were found most promising, which has the potential to increase the average yield of maize in Medebay zana and Laelay Adiabo districts and is therefore recommended to demonstrate for general cultivation in both districts.
西北提格雷地区开放授粉玉米品种适应性及产量性能评价
为了评价改良玉米基因型的性能,于2014年和2015年主种植季在埃塞俄比亚提格雷西北部的Medebay zana和Laelay Adiabo区进行了试验。试验采用完全随机区组设计,设3个重复。记录株高、穗高、穗数/畦、株高和穗高、开花至50%的天数、出丝、成熟度、籽粒产量和千粒重。在大多数环境下,各品种间的所有性状均存在显著差异,但在基因型的环境组合方面,大多数性状的结果不显著,建议在不同环境下重点推荐稳定的基因型。品种Gibe-2和Gibe-1产量最高,分别为5114.15 kg ha-1和4964.96 kg ha-1。与梅尔卡萨2号和其余品种的标准对照比较,梅尔卡萨6号为早熟品种。品种Gibe-1株高和穗位最高,分别为237.28 cm和120.80 cm。这个品种可能容易倒伏。这些品种具有广泛的遗传背景,因此籽粒产量在1748 ~ 5114 kg hm -1之间。因此,总体而言,Gibe-1和Gibe-2玉米品种最有潜力,有可能提高Medebay zana和Laelay Adiabo地区的玉米平均产量,因此建议在这两个地区进行普遍种植示范。
