Abstract

The performance evaluation of maize genotypes  at a specific growing region is a key to crop improvement. The objectives of this study were to evaluate grain yield of maize genotypes at Bijayanagar (Mahatgaun VDC) and Tallo Lorpa (Dillichaur VDC), Jumla District of Nepal during spring seasons of 2012 and 2013. The maize genotypes were significant (P< 0.05) for grain yield, days to tasseling and silking and  disease scoring where as anthesis-silking interval, plant height and ear height were non significant. The pooled analysis of the results showed that the highest grain yield was produced by Ganesh-1 (4830 kg/ha) followed by KKT-POP (4408 kg/ha), KKT-14 (3952 kg/ha) and MGU-08 (3913 kg/ha, respectively. From this study, Ganesh-1, KKT-POP, KKT-14 and MGU-08 could be preferable choice for cultivation in Jumla district of Nepal.

尼泊尔Jumla地区玉米性能评价:从产量角度看
玉米基因型在特定生长区域的性能评价是作物改良的关键。本研究的目的是评估尼泊尔Jumla地区Bijayanagar (mahatgoun VDC)和Tallo Lorpa (Dillichaur VDC)在2012年和2013年春季的玉米基因型产量。玉米基因型在籽粒产量、抽雄吐丝天数和病害评分上均有显著差异(P< 0.05),而在花丝间隔、株高和穗高上均无显著差异。综合分析结果表明,甘尼什-1籽粒产量最高(4830 kg/ha),其次是KKT-POP (4408 kg/ha)、KKT-14 (3952 kg/ha)和MGU-08 (3913 kg/ha)。研究结果表明,Ganesh-1、KKT-POP、KKT-14和MGU-08是尼泊尔Jumla地区较好的栽培品种。
