is a new early spring hybrid of cabbage selected by crossing two promising self-incompatible lines, 8101-2-20-2 and 8180-1-2-1. The F_1 hybrid has good quality, early maturity and high productivity. It can be harvested 50 days after transplanting. The yield is about 49.5～ 57.0 t/ ha. It s yield, commercial quality, hybrid rate and seed germination are all much higher than Zhonggan No. 11, a widely used spring F_1 hybrid in China. The new F_1 hybrid has now been released on a large scale in northern China.

The resistance ratios (RR) of Plutella xylostella in Wuhan were 197.47-and 100.29-folds to fenvalerate and phosemet compared with a susceptible ( S) strain. The RR declined when the Wuhan field strain ( WH) was reared on fresh cabbage leaves in the laboratory.There was no resistance in WH strain after 20 generation because of complete resistance reversion.The susceptibility of both WH and S strain to methomyl was low and the resistance reversion was also slow. The application of this study in insecticide re...

Heterosis and combining ability were analysed for 12 combinations by incomplete dialle of 3 strile lines and 4 inbred lines. The results showed: positive heterosis occured in plot yield, single root weight, root length and width. Heterosis of plot yield and single root weight were the highest, General combining ability was more important than specific combining ability.General combining ability of 30 family (B_3) indicated had higher positive values for plot yield,single root weight, root length and width. ...

The correlation analyses among the data of electric conductivity, growth chamber test, chlorophyll content and summer natural field test showed that the former two methods could reflect the heat tolerance of heading Chinese cabbage. The electrolyte leakage rate of the blade cell and the heat damage index had a markable negative correlation with heading rate under high temperature. Whereas, after high temperature treatment, chlorophyll content did not expressed relationship with head formation, and could not...

Promotive effects of choline chloride (CC) on cotyledon growth and adventitious root emergence in hypocotyl cut from 7d seedlings of Cucumis sativus were observed under controlled conditions. CC greatly made etiolated cotyledons greening at 70μmol/ L, expanding in area and inreasing in fresh and dry weights at 50￣ 400mg/ L. It was also obvious that CC at 100μmol / L could stimulate adventitious root differentiation in down end of hypocotyls when the cotyledon-hypocotyl segment was used as exprimental system...

The occurrence patterns of gourd seedling-laying caused by Pythium aphanidermatum and Rhizoctonia solani were almost the same. Most of the seedlings were infected by pathogens before the sprouts had come up out of the ground. The younger seedlings were more seriously infected. The disease occurred more seriously in the garden and greenhouse soil where there were more pathogens. Low temperature high or middle humid soil, Low light intensity, slightly high pH soil and deep soil cover over seeds were favourabl...
