不同鲜食玉米品种农艺性状和产量的比较研究

Comparative on Agronomic Characters and Yield in Different Fresh Maize

为探讨鲜食玉米的优良性状,引进当地主推的鲜食玉米品种,分为糯玉米、甜糯玉米、甜玉米3组,对它们的生育期及农艺性状进行研究。结果表明:所有糯玉米品种比甜玉米品种在生育期、株高、百粒质量、产量等方面差别明显;某些品种表现出个体差异,甜玉米品种T2和T7的穗长和穗粗要优于糯玉米品种,甜玉米品种T2的穗行数和行粒数较高,N9无秃尖。糯玉米品种中的N7、N9的农艺性状表现好于其他品种。

In order to explore the excellent performance of fresh maize,the main varieties of fresh maize introduced were introduced and divided into three groups:waxy maize,sweet waxy maize and sweet maize.The results showed that:compared with sweet maize varieties,all waxy maize varieties had obvious differences in growth period,plant height,100-seed weight and yield;some varieties showed individual differences,and the ear length and ear diameter of sweet maize T2 and T7 were better than those of waxy maize;T2 had higher ear row number and grain number per spike,and N9 had no bald tip.The agronomic characters of N7 and N9 in waxy maize were better than other varieties.
