Analysis on Correlativity of Three-ear-leaves of Inbred line and Hybrid-strain Yield of Glutinous Maize
Investigated the three-ear-leaves characters and yield of sample plant of 15 stabe Glutinous Maize inbred lines and their hybridized combination,Analysised the correlations of three-ear-leave's area,the result showed that the leaf under the ear in three-ear-leaves is the longest and the leaf above the ear is the widest.Each leaf area no significant different.Sum of leaf area in three-ear-leaves is singificantly positive correlative between parents and hybridized combination.It was the same with yield of sample plant for hybridized combination in reciprocal cross combination,in case the area of three ear-leaves for female parent is big,the area to hybridized combination is big,yield is high.By contrast,the area is small,the yield is low.when selecting hybridized combination,it is beneficial to high yield that using the bigger area of three-ear-leaves as female parent.key words:Glutinous;Maize;Inbred line;Hybridized-combination;Three ear leaves;Yield of single plant;Correlativity.
