山核桃与薄壳山核桃种间杂交F1代果实及苗木性状变异分析
Genetic analysis on fruits and seedlings characters variation of F1 between Carya cathayensis and C. illinoensis
摘要
Abstract
The main characters of fruits and seedlings of F1 obtained by hybridization between male parent Corya illinoensis and female parent Carya cathayensis were examined. The results showed that characters of F1 were significantly different from that of control in terms of weight and size of fruit and seed, height and diameter of seedlings growth. The weight, height and diameter of fruits were higher than the control by 29. 1％, 7.2 ％, 11.0 ％, respectively. And the weight, height and diameter of seed were higher than the control by 30. 9 ％ ,8. 13 ％ ,12.4 ％, respectively. The average height and diameter of 3 years old seedlings were higher than the control by 18. 1％ and 19. 7 ％. And it could achieve 29. 2 ％ and 32. 81％ after having planted for2 years. Therefore, It was effective to increase fruit size and improve characters through interspecific hybridization. Seedlings with double embryos in F1 generation accounted for 10 ％ which was 5 times higher than the control.关键词
