大豆辐射育种与杂交育种相结合能选育出综合性状优良的品种,用此法育成的大豆品种黑农16具有早熟、高产、光合效率高29.3CO2毫克/平方分米、叶小时,经济系数高0.539;品质优良,含油量高22.62%;适应性广,耐轻盐碱,并具有一定的耐荫特性。1979年省内种植面积仍达120万亩。1978年荣获全国科技大会的奖励为重大科技成果之一。利用热中子处理地理远缘的杂交后代,从中选育出高产并具有理想株形的哈77—7594品系和比原材料早熟32天的极早熟品种哈75—6222并通过黑农16及哈77—7594的选育,对辐射育种与杂交相结合的材料选择、引变剂量、后代处理等问题报导于下,以供讨论。
Soybean radiation breeding combined with crossbreeding can breed fine varieties. The cultivated soybean cultivar Heinong 16 has the advantages of early maturity, high yield, photosynthetic efficiency 29.3CO2mg / dm2, leaf hour, high economic coefficient 0.539; high quality, high oil content of 22.62%; wide adaptability, resistance to salt and alkali, and shade with certain characteristics. In 1979, the planting area in the province still reached 120 million mu. In 1978 won the award of the National Science and Technology Conference as one of the major scientific and technological achievements. Using thermal neutrons to deal with the geographically distant hybrid progeny, we selected the high-yielding line Ha-77-7594 with the ideal plant shape and the very early-maturing variety Ha 75-6222 which was 32 days earlier than the raw material. -7594 Breeding, the combination of radiation breeding and hybrid materials selection, variable doses, offspring and other issues reported below, for discussion.
