Abstract:
Value,mid-parent heterosis and over-parent heterosis of 33 characters of cucumber hybrids and plants was systematically studied,their correlation with early maturity and productivity were analyzed.The results showed that the total yield was significantly correlated with total fruit numbers,average fruit weight,yield of main stem fruit,yield of branch fruit,main stem diameter,growth days,etc.The above characters showed obvious heterosis.Early yield was significantly correlated with the node of first female flower,female flower rate and the yield of main stem as well as branch fruit,stem length,leaf area,etc.Value,mid-parent heterosis and over-parent heterosis of the node of first female flower and female flower rate were significantly correlated with early yield at the 0.01 level.Measures to achieve higher early and total yield in cucumber breeding and cultivation were also suggested based on the above results.
