Advances of research on polyploid breeding of vegetable crops 蔬菜多倍體育種研究進展
It is extraordinarily important to select tetraploid lines for breeding sugar beet polyploid varieties 摘要四倍體品系選育是甜菜多倍體育種不可缺少的重要環(huán)節(jié)。
Since the first tetraploid was obtained in 1939 , polyploidy breeding has always been the focus of watermelon breeding 從1939年獲得第一個四倍體西瓜以來,多倍體育種就一直是西瓜育種的一個熱點。
In this article , ways of polyploidy breeding , the identification of polyploidy , application of watermelon polyploidy , and the prospective of watermelon polyploid breeding are reviewed 文章概述了西瓜多倍體的產(chǎn)生途徑、鑒定方法,西瓜多倍體育種的應用以及研究新動向。
Forty - two steady tetraploid lines induced by the colchicines had been created from 1994 to 1996 , three high - yield lines and eight high - sugar content lines have been selectively bred through plot identification trial during the years of 2001 to 2003 1994 ~ 1996年用秋水仙堿誘變出四倍體穩(wěn)定系42個,經(jīng)2001 ~ 2003年小區(qū)鑒定,選育出高產(chǎn)品系3個,高糖品系8個,為甜菜多倍體育種創(chuàng)造了寶貴的基礎材料。
