摘要
为选育出适宜贵州高海拔山区种植的杂交玉米新组合,用六盘水职业技术学院自选的自交系"H4-2"为母本,"SC122"为父本杂交配组,选育出玉米新组合荷玉1号。该组合在2008-2009年贵州省高海拔特殊生态区组2年区试中,平均单产619.78 kg/667m2,比对照(毕玉6号)增产10.91%,2年18个试点中,增产点16个,占88.89%,生育期151 d,比对照晚熟2 d。该组合在贵州西部高海拔特殊生态区具有广泛的适应性和良好的丰产性,于2010年7月通过贵州省农作物品种审定委员会审定并命名。
Heyu 1,a new hybrid maize variety,was bred from H4-2（♀）bred by Liupanshui Vocational and Technical College × SC122（♂） to breed new hybrid maize combination which was suitable to be planted in high altitude mountainous area of Guizhou province.The average yield of Heyu 1 in the high altitude special ecotope group of Guizhou province was 619.78kg/667m2,10.91% higher than CK（Biyu 6） and the sites with yield increase were 16 among total 18 sites during 2008-2009.The growth period of Heyu 1 was 151d,2d later than CK.Heyu 1 with the wide adaptability and good yielding ability was approved by Guizhou Committee of Crops Variety Examination in July,2010.
