摘要/Abstract

摘要： 通过对南瓜远缘杂交育种的研究,为去劣选优与基因纯化,培育出后代优势更强的南瓜种质资源提供特优新材料。在云南中南部地区,从多个印度南瓜新材料中选出雌花发生早而多的单株与中国南瓜杂交,获得F1表现良好的新一代南瓜杂交良种供生产应用。研究结果表明,通过纯化后的远缘基因重组,获得的后代南瓜良种,在表现上耐低温、生长势强、抗病早熟、优质高产、耐贮运等方面都有优良性状。经多代基因纯化后的远缘杂交优势利用新技术,虽然育种所需时间较长,但能有效地提高南瓜F1的品质和经济价值。

Abstract: Through the research on pumpkin distant hybrid breeding, excellent new materials can be provided for removing the bad selection, retaining the good, purifying the gene, and cultivating the pumpkin germplasm resources with stronger offspring. In central and southern Yunnan, a single plant with early and more female flowering was selected from a number of new Indian pumpkin materials and hybridized with Chinese pumpkins to obtain a new generation of hybrid pumpkin varieties with good F1 performance for production applications. The results of the study showed that the offspring pumpkin varieties obtained through purified distant genetic recombination have excellent combinations in performances such as low temperature tolerance, strong growth potential, disease resistance, early maturity, high quality, high yield, and easier for storage and transportation. After multiple generations of gene purification, the advantage of distant hybridization with the new technology becomes obvious. Although the breeding takes a longer time, it can effectively improve the social and economic value of pumpkin F1.
