  It showed that six quality characters among different varieties with same bulb color or different bulb color were different. White bulb s tightness and dry weight,soluble solid,soluble sugar and pyruvic acid content were higher than those of other bulb color varieties. Red bulb varieties have the highest protein content of three bulb color varieties. Soluble solid content was very significantly correlated with other characters except protein content. Bulb tightness was very significantly correlated with sol...

  Leek 49 cultivars or crossing combinations were used for conducting the correlation and path analysis of six main characters which form the individual production of leek. The result showed that the leek yield per plant had very significant positive relationship with sheath thickness,and blade length,plant height and blade number of leek. The plant height had the greatest influence on the yield of leek,followed by sheath thickness. The plant height,blade length and sheath thickness were main factors which di...

  Winter tomato varieties were improved by using variety Lima as a male parent to cross to some recurrent winter tomato varieties 413,452,499,514 and 560. Progenies of the hybrids were selected by pedigree method. The inbred lines of the crosses showed 12 %-32 % higher yield than control varieties VF134-1-2 and Lima.The inbred line from crossed 452×351 showed the highest yield,44.29 t·hm -2 and while varieties Lima and VF134-1-2 showed 33.29 and 33.66 t·hm -2,respectively. Most of the inbred lines sho...
