  29 worldwide representative cucumber materials(K1-K29)and 4 populations from 2 crosses were employed for studying the resistance correlation between downy and powdery mildews.The result showed that correlation coefficients of disease indexes between downy mildew and powdery mildew were 0.619 8 and 0.677 2 at the seedling and mature stages respectively,which were extremely significant.The correlation coefficients of downy mildew and powdery mildew for BC1P1 and F2 individuals from the cross between K8 and K1...

  The inheritance of heat tolerance in tomato was studied with 6×6 half diallel crosses.Two parents with different heat tolerance and their progeny of F1,F2,B1,B2 and P1,P2 involved in the experiment of heat treatment.The results from genetic model analysis and genetic parameters estimate showed that the character of heat tolerance in tomato was fit for a model of additive-dominance,the additive effect played more important roles than the dominant effect,the variance of general combining ability was predomina...

  Effects of fresh male flower and flower buds storage temperature on cucumber pollen viability were studied.The results indicated that pollen survived longer in lower temperature,pollen viability in 5,10 and 15 ℃ were 60,44 and 34 h longer than that in 25 ℃ respectively;collecting male flower buds late in the afternoon(about 18:00)is better than that in earlier time;flower buds at 5 ℃ storage maintained the longest pollen viability,but was not better for flowering and pollen dispersion,so treating flower bud...

  By adopting complete diallel crossing method,inheritance of powdery mildew in bitter ground was studied at seedling stage.The results showed the resistance was controlled by at least two pairs of genes,and was incompletely recessive.Effect of backcross was very significant and that of reciprocal cross was not.Resistance was dominated by nuclear genes,narrow inheritability was comparatively high.The resistance was in keeping with additive-dominance model,and dominance was dominating,and showed a quantitative...
