【摘要】 通过多代蕾期人工自交、系统选育的方法,得到5个优良抱子甘蓝新品系,并对它们的主要园艺学性状作了综合评价。其中,以BC-2和BC-3的结球数多、散球少,并以BC-3的球型佳,单球重大;BC-5的综合性状最好;BC-1的株型最矮、球型最小、叶型皱,颇具特色。对各新品系花期、蕾期自交结实率的统计分析结果表明,各品系间及同一品系内不同植株间的自交亲和性均存在差异,通过强化筛选,可获得花期自交不亲和性较强的优良新品系。更多还原

【Abstract】 The 5 excellent new lines of Brussels sprouts, selected and bred through manual selfing of many generations, were comprehensively estimated on their main horticultural characteristics, and their adverse resistance and self incompatibility were also studied. The results showed that new line BC-1 had good quality and good heading characters, and BC-3 had good heading characters, more number of heads and high yield. The statistical analysis on the selfing setting percentages of flower bud stage and blooming stage showed that there were difference of self-incompatibility between the new lines and between the plants of the same line. Through intensive screening, the strong self-incompatible plants could be got.更多还原
