摘要: 甜糯玉米是鲜食玉米发展的重要方向,甜糯双隐玉米自交系是配制甜糯玉米新品种的重要材料。利用广西地方糯玉米种质创制优良糯玉米自交系,采用系谱法、籽粒碘显色法选育甜糯双隐玉米材料,育成3 个优良甜糯双隐玉米自交系GTL270、GSL121、GSL125,利用其组配3 个高产优质的鲜食甜糯玉米新组合并通过广西审定,丰富了广西甜糯玉米市场。

关键词: 甜糯玉米, 鲜食玉米, 甜糯双隐自交系, 种质

Abstract: Sweet-waxy maize is an important direction for developing fresh-eating maize.The sweetwaxy double recessive maize inbred line is an important material for preparation of new sweet-waxy maize varieties.Through creating superior waxy maize inbred line by local waxy maize germplasm in Guangxi;and breeding sweet-waxy double recessive maize material by pedigree method and grain iodine coloration method,this study succeeded in breeding 3 excellent sweet-waxy double recessive maize inbred lines,namely ‘GTL270’,‘GSL121’ and ‘GSL125’,which were utilized to prepare another 3 new combination of fresheating sweet-waxy maize with high yield and superior quality.This combination was examined and approved by Guangxi,thus enriched the market of sweet-waxy maize in Guangxi.

Key words: sweet-waxy maize, fresh-eating maize, sweet-waxy double recessive maize inbred line, germplasm
