【摘要】 针对陕西关中地区的生态条件、栽培技术和品种资源现状,将系统科学引入辣椒育种领域,以5个亲本和利用该亲本半双列杂交配制的10个F1杂交组合为材料,研究了早熟(800 ～1200kg(667m2)-1)、高产(4000～4500kg(667m2)-1)品种的品种模式,结果表明:该品种模式的主要农艺性状取值为:株高54．9～59．5cm,株幅38．9-43．1 cm,侧枝数／株2～2．8个,始花节位7．8～8．8节,开花期102．9～106．5d,果重28．7～48．7g。早期结果数／株2．6～4．9个,总结果数／株17．2～29．6个。更多还原

【Abstract】 Acording to ecological conditions, cultivation technique and germplasm status at Guanzhong region in Shaanxi province, system science was applied in hot pepper breeding field. Choosing 5 parents and 10 F1 obtained from half- diallel cross between these parents as experimental materials, the cultivar model with the characteristics of earliness (800 - 1200kg (667m2) -1) and high yield (4000 -4500kg (667m-1) ) was optimized. The results showed that the agronomic characters of this cultivar model was as followed: plant height 54.9-59.5 cm, plant spread 38.9-43.1 cm, number of second branches/plant 2 - 2.8, node of first flower 7.8 - 8.8, days to flowering 102.9 - 106.5, fruit weight 28.7-48.7 g, number of early fruits/plant 2.6-4.9, number of total fruits/plant 17.2-29.6.更多还原
