摘要
大豆窄行密植栽培技术是黑龙江省目前主要的大豆栽培技术之一,其较常规栽培技术平均增产16%-22%,但现在与该栽培技术配套的半矮秆大豆品种还很少。利用美国矮秆晚熟大豆品种Hobbit与当地早熟大豆品种配制2个单交组合、2个回交组合,通过对各组合后代半矮秆大豆早熟性和矮生性研究,认为改良美国矮秆基因最佳组配方式为：（当地早熟品种×美国矮秆晚熟品种）×当地早熟品种,其次为当地早熟品种×美国矮秆晚熟品种。利用美国矮秆基因可以选育出适宜当地的半矮秆大豆新品种。
Solid-seeded cultivation is one of major soybean cultivation techniques in Heilongjiang Province, however, few semi- dwarf soybean cuhivars are found to suitable for the cultivation technique. The present study investigated the best parents combination mode for selecting semidwarf soybeans with suitable maturity and plant stature. Two single cross and two backcross combination were made with American soybean cultivar Hobbit, with short statute and late maturity, and local early maturity soybean cuhivar 211 and Baofeng 7. The genetic mode of maturity and plant high in filial generation was investigated. Results showed the best combination mode for utilizing American short statute soybean was（ China early maturity soybeans × Hobbit） × China early maturity soybeans,then was China early maturity soybeans × Hobbit.
