前几年,我场接受省种子公司从意大利等地引进的451—82和393—81等番茄杂交制种任务。结合工作实践,提出以下几项措施: 1.搞好杂交制种用具消毒。在杂交制种前,镊子、授粉笔或授粉器等用具和手均用70%酒精棉球进行消毒,防止产生非目的性杂交种子。 2.做好花粉采集和储存工作。在父本植株上选择发育正常的花蕾,先进行套袋,经2～8天后,花将开放或刚开放而花粉尚未散出时,除去套袋剪取花朵,带回室内,放在黑光纸上,然后用镊子将花冠去掉,并将花药——取下,放于垫黑光纸的培养皿中,置干燥处晾干,使花粉散出;也可以用解剖针从花药内侧纵剖取出花粉。如果进行大面积的杂交制种需大量花粉时, A few years ago, I accepted the provincial seed companies introduced from Italy and other 451-82 and 393-81 and other tomato hybrid seed production task. Combined with work practices, put forward the following measures: 1 do a good job hybrid sterilized appliances. Prior to hybridization, utensils and hands, such as tweezers, pollinators or pollinators, are sterilized with 70% alcohol cotton balls to prevent the production of non-targeted hybrid seeds. 2. Do pollen collection and storage work. Select the normal development of the bud in the parent plant, the first bagging, after 2 to 8 days, the flower will be open or just open and the pollen has not yet been shed, remove the bagging cut flowers, back to the room, on the black paper , And then use the tweezers to remove the corolla, and the anthers - removed, placed on a mat black mat paper, set dry place to dry pollen; also dissection needle pollen can be taken longitudinally from anther pollen . If a large area of ​​hybrid seed production requires a large number of pollen,
