食用及青割玉米品種改良

Abstract

甜玉米育種：93年春作甜玉米自交系共分離育成S1~S6等870品系。單雜品系組合結合力檢定春作以PSC922129公頃含苞葉鮮穗產量18,130公斤最高較CK1(華珍)16,210公斤增加11.9%。秋作公頃產量，以PSC932083公頃含苞葉鮮穗產量20,700公斤，較對照種華珍(CK1)之公頃含苞葉鮮穗產量16,350公斤高26.6%，秋作三系雜交品系組合力檢定以PTW932147公頃含苞葉鮮穗產量18,340公斤較對照種華珍(CK1)公頃含苞葉鮮穗產量18,830公斤少2.6%。 The results of the breeding program were divided into four parts. 1)Sweet corn: 870 S1-S6 inbreds were obtaind. In the single cross test held in 2004 spring crop, PSCP22129 was better in ear production than the check. However, PSC932083 performed the highest ear yield in 2004 fall crop, and outyielded the check, Hwazein by 26.6%.
