摘 要：
为了拓宽甜瓜种质资源,将7份经过神舟8号搭载的北方寒地甜瓜亲本材料进行地面试种,筛选优良的变异株系。结果表明:经地面试种后选择具有重演性、可遗传的变异株系10个,又经多代选择出性状稳定、品质及抗病鉴定优良的变异株系4个。其中SP01-008-01A-01A果形变阔梨形,种子变褐色,含糖量增加2.00百分点,单瓜重比对照增加70g。SP01-113-06B-06B果皮变墨绿,含糖量增加1.00百分点,种子变褐色。SP03-128-08A-08A果实乳白色且变无环裂,奶香味浓。SP03-061-03C-03C瓜阔梨形,果实乳白色且变无环裂,奶香味变浓,单瓜重增加20g。试验证明北方寒地甜瓜太空诱变呈多方向变异,数量性状遗传变异明显,瓜皮颜色变深、瓜肉瓜瓤及种子颜色有改变,含糖量普遍增加、单瓜重增大、抗病性普遍增强。

摘 要：
In order to broaden the melon germplasm resources,seven melon parent materials of the cold region after carrying the Shenzhou the 8th were planted on the ground to screen excellent mutant strain.The results showed that through a repeat of the experimental planting,heritable variation in lines 10,multi-generation selection trait stability,excellent quality and disease resistance identified mutant 4lines.SP01-008-01A-01 A strain broad pear-shaped fruit,seeds turn brown,the sugar content increased and 2.00 percent,fruit weight increased 70 g compared with the control.SP01-113-06B-06 B was dark green rind,the sugar content increased1.00 percent,the seeds was brown.SP03-128-08A-08 Afruit was milky and acyclic crack,milk fragrance was thick.SP03-061-03C-03 Cwide melon pear,fruit was milky and acyclic crack,thick milk flavor,and fruit weight increased 20 g.Test proved north cold melon space mutation and showed multiple directions variation,fruit discoloration deep,fruit flesh and seeds had chang been on color,sugar content generally increased,fruit weight increasing and a general increasing in disease resistance.
