Study The Clones Of Cabernet Sauvignon And Cabernet Franc Grapevine From Franc

The experiment was done in Zhang jia gan vineyard of yangling shannxi in 2002～2003.This experiment materials are clones introduced from Franc in 1998:Cabernet Franc:98-CF-312,98-CF-214,98-CF-210。Cabernet Sauvignon:98-CS-191,98-CS-405,98-CS-341。Morphological characteristics(young shoot,young leaf and mature leaf),traits of grape berries(bunch of fruit,single fruit,seed and physi-chemiraltraits of fruit),phenology(budbreaking stage,blooming stage,veraising stageand fruit maturing stage) and cultivating characteristics(viger,factors of production and diseases resistance)were studies systematically.Brew,fundamental ingredieng of wine and taste were studied too.The results show:1. Every clones of Cabernet Franc and Cabernet Sauvignon have not obvious difference in botanical characters. 2. The vigour of growth of Cabernet Franc and Cabernet Sauvignon is middle. The weight of bunch is middle.The weight of berry is middle. The weightiest bunch is 98-CF-312 and 98-CS-191.3. In every clones of Cabernet Franc,98-CF-210 is the highest bud burst rate,98-CF-214 is the higtest fruit-set rate, fruit/young shoot-per and fruit-set coefficient.In every clones of Cabernet Sauvignon,98-CS-341 is the highest bud burst rate, 98-CS-191 is the highest fruit-set rate, fruit/young shoot-per,98-CS-405 is the highest fruit-set coefficient.4. Cabernet Franc and Cabernet Sauvignon have not obvious difference during veraising stage,the other phenology, Cabernet Franc is prior Cabernet Sauvignon to 1-2 weeks.5. During the maturation, increasing sugar of every clones rapidly in the beginning of veraising stage.Total acid contents reduced. The change tends slowly, when the berry is maturate.Sugar-acid ratio of every clones is high,from 20 to 27. In the clones of Cabernet Franc, the clone of 98-CF-210 is the highest of sugar contents. 98-CF-214 has the lowest total acid contents and the highest sugar-acid ratio in all clones,its quality is good.In the clones of Cabernet Sauvignon, the clone of 98-CS-341 has the highest sugar contents, lowest acid contends and highest sugar-acid ratio, its quality is good. 6. For analyzing the resistance of disease, we use nature infection in field . The results are: In the clones of Cabernet Franc, the most powerful resistance to Coniathyrium diplodiella (Speg.) Sacc is 98-CF-214,the most powerful resistance to Plasmopara Viticola is 98-CF-312.In the clones of Cabernet Sauvignon, the clone of 98-CS-191 has the most powerful resistance to Coniathyrium diplodiella (Speg.) Sacc , and 98-CS-341 has most powerful resistance to Plasmopara Viticola.7. In the brew experiment of every clones , 98-CF-214 and 98-CS-405 can brew dry red wine with highly quality.8. 98-CF-214,98-CS-405 are better clones to disease resistance,charater of berries and vinification characteristics.
