摘要:

本研究基于远缘杂交诱导技术创制丝瓜双单倍体,为丝瓜优良品种的培育和遗传改良提供理论依据。试验以丝瓜杂交品种TL 01(2n = 26)为母本,与葫芦科5种不同父本杂交,对获得的杂交后代进行倍性鉴定,并自交获得自交一代,通过简单重复序列(simple sequence repeats,SSR)标记鉴定其是否为双单倍体。结果表明,在5个杂交组合中,共收获12粒饱满种子,仅西瓜诱导获得的种子收获2株再生植株,编号T-1和T-2,其中T-1植株自交收获63粒后代。利用SSR标记鉴定自交一代,发现6对SSR标记在自交一代单株间的带型一致,表明该再生植株为双单倍体。双单倍体丝瓜育性得到恢复,可以利用种子繁殖。

Abstract:

In this study,we developed diploid Luffa through distant hybridization induction technology,providing a theoretical basis for the cultivation and genetic improvement of excellent Luffa varieties. Luffa hybrid variety TL 01(2n = 26) was utilized as the female parent,five different male parents of Cucurbitaceae were hybridized. The obtained hybrid offspring were subjected to ploidy identification and selfing to obtain the first generation. Simple sequence repeats (SSR) markers were used to identify whether they were diploids. The results showed that a total of 12 plump seeds were harvested from the five hybrid combinations. However,only watermelon pollen-induced harvested seeds were successfully regenerated from two plants,labeled T-1 and T-2. 63 seeds were harvested from the selfing of T-1 plants. Using SSR markers to identify the first generation of selfing,it was found that six pairs of SSR markers had consistent band patterns among the first generation of selfing,indicating that the regenerated plant was diploid. The fertility of diploid Luffa has been restored and can be propagated using seeds.
