【摘要】：南瓜(Cucurbita moschata)是葫芦科重要的蔬菜作物之一,具有丰富的营养和保健功能,近年来发展非常迅速。但是,适应不同市场需求南瓜品种选育的滞后与南瓜产业的迅速发展呈现出极不相适应的态势,这严重阻碍了我国南瓜产业的进一步发展,因此,选育高产、优质、适应不同市场需求的南瓜新品种具有重要意义。1、分别以从国外引进的南瓜品种中自交分离获得的自交系JP-1为父本,HP-35为母本,配置F1代杂交组合,成功选育出优质、丰产印度南瓜新品种“红栗2号”。2、红栗2号成功地克服了目前我国主栽红皮印度南瓜品种中存在的一些缺陷,综合性状非常优良。该品种全生育期110 d,春季栽培果实发育期约45 d；果实高扁圆形,果皮红色,果肉橙红色,肉厚约3.8cm,质粉味甜。平均单果质量2.7 kg,667m2产量3000kg左右。坐果性好,生长势强,耐低温、高温,抗病性强适应性广。适宜全国各地栽培。3、不同栽培方式对红栗2号南瓜品质的影响存在显著差异,当采用爬地双蔓整枝的方式种植时,红栗2号南瓜的综合品质最优。4、通过对良种进行配套良法种植研究,总结出了一套红栗2号南瓜的高产优质栽培技术规程。5、通过对红栗2号南瓜制种经验的总结,归纳出了一套红栗2号南瓜亲本自交系繁殖和健康种子制种技术规程。
[Abstract]:Cucurbita moschata (Cucurbita moschata) is one of the most important vegetable crops in Cucuraceae. The lagged breeding of pumpkin varieties to meet the different market needs and the rapid development of pumpkin industry show a very unsuitable situation, which seriously hinders the further development of pumpkin industry in China, therefore, breeding high yield, good quality. The new pumpkin varieties adapted to different market demands have important significance. The inbred line JP-1 obtained from the imported pumpkin varieties was used as the male parent HP-35 as the female parent respectively. The hybrid combination of F1 generation was used to select the high quality and high yield Indian pumpkin variety "Hongli 2" and "Hongli 2", which successfully overcome some defects existing in the main red skin Indian pumpkin varieties in our country at present. The comprehensive character is very good. The whole growth period of this variety is 110 days, and the development period of spring cultivated fruit is about 45 days. The fruit was high oblate, red pericarp, orange-red pulp, thick flesh about 3.8 cm, fine powder and sweet taste. The average weight of single fruit was 2.7 kg / kg ~ 667m ~ 2, the yield was about 3000kg / kg, and the fruit setting was good. Strong growth potential, low temperature tolerance, high temperature, wide adaptability to disease resistance, suitable for cultivation around the country. Different cultivation methods have significant differences on the quality of red chestnut 2 pumpkin. When the double vine was planted by climbing the ground, the comprehensive quality of Hongli 2 pumpkin was the best. 4. In this paper, a set of high yield and high quality cultivation technique of Hongli 2 pumpkin was summarized, and the experience of seed production of red chestnut 2 pumpkin was summarized. A set of technical rules for breeding and healthy seed production of red chestnut 2 pumpkin parent inbred line was summarized.
