茄子杂交种优势明显 ,目前杂交制种一般采用自交系间人工杂交的方法 ,用镊子或徒手进行杂交。正常情况下 ,一般 6 6 7m2 制种可产杂种 4 0～ 50 kg。生产上杂交制种时 ,往往出现杂交后落花落果现象 ,导致种子产量下降。经观察和分析 ,制种时落花落果的主要原因如下 :1　温度障 Eggplant hybrids have obvious advantages. At present, crossbreeding is generally done by artificial crosses between inbred lines, and hybridization is performed with tweezers or bare hands. Under normal circumstances, the general 6 6 7m2 seed hybrids can produce 40 ~ 50 kg. Production of hybrid seed production, often after the phenomenon of falling flowers after fruit drop, resulting in reduced seed yield. After the observation and analysis, the main reasons for the drop of flowers during seed production are as follows: 1 temperature barrier
