Issue Date: | 6-Mar-1982 | Publisher: | 農業試驗所 | Journal Volume: | 31 | Journal Issue: | 1 | Start page/Pages: | 51-58 | Source: | 中華農業研究 | Abstract: | 1)從本試驗之研究得知,蘆筍之染色體為6 長4 短(6L + 4S),經核型分析結果,其核型為:K = 2n = 20 = 2L1st +2L2 st + 2L3 st + 2L4 st + 2L5 st + 2L6 st + 2Slm + 2S2 m + 2S3 m + 2S4 m = 61.4μ,其中一對染色體(L6)之長臂上有附隨體,所有大型染色體之長臂上,均有二次縊縮現象。 2)兩性株SH69-1-2 之花粉母細胞,369 個細胞中,有360個呈現正常之配對,僅有9 個呈9II + 2r;而第一後期之176 個細胞中,有2 個具染色體橋,其餘均正常。 3 )以Connover’s Colossal 無花青素之植株為親本之雜交F1,其花粉稔性在95~99%之間,♀:♀:♂=5.2 : 1 : 6.2,含與不含花青素之個體比率為1 : 1.4。另又從F1品系間、及F1品系與品種間之不同性別做多數雜交組合,獲得多量之種子,供次代育種研究之材料。 |
