Analysis About Features Of Wheat Hybrid Starch Gelatinisation

This study is based on the hybrid of 5 parents, Zimai 12, Lumai 14, 924142, PH85-16 and Sn2618. The result show the analysis about correlations and hybrid vigor of wheat hybrid starch gelatinisation by RVA. This study show that there are high correlations among the PV , TV, FV, SB and PT of the 5 parents. There are a few minus correlations of BD to PV, TV, FV and PT. There are high correlations among PT, TV, FV of F1. The PV and SB of F1 is high correlated. There is minus correlaton between PV and BD of F1.There is correlation between orthogonal hybrid and its femal parent on PV. The reciprocal hybrid and its male parent is the same. The PV of F1 is mainly influenced by its male parent when Zimai 12 is one of its parents, and the PV is inclined to the low parent. As Lumai 14 is the parent, the PV is mainly influenced by the female parent. As PH 85-16 or 924142 is the parent, the PV is mainly influenced by the male parent. When the parent is Sn2618, the PV is mainly influenced by the female parent, and is inclined to the low parent.The correlation of TV between orthogonal hybrid and the AP (average of parents) is high. The TV of F1 is mainly influenced by the AP. As Zimai 12 is one of the parents, the TV of F1 is influenced by their two parents, and the TV of F1 is inclined to the low parent. As Lumai 14 or PH 85-16 is the parent, the TV of F1 is influenced mainly by the female parent. When the parent is 924142, the TV of F1 is mainly influenced by the male parent ,and is inclined to the low parent. When Sn2618 is the parent, it is the same.The correlation of FV between orthogonal hybrid and the female parent is the highest one. When Zimai 12 is one of the parents, the FV of F1 is influenced by two parents. When the parent is Lumai 14, it is mainly influenced by the female parent. As PH 85-16 or Sn2618 is one of the parents, the TV of F1 is mainly influenced by the other one.The highest correlation of PT is the correlation between F1 and AP. That is , the PT of F1 is main ly influenced by AP, and it is inclined to the low parent. When Zimai 12 or Sn2618 is one of the parent, it is mainly influenced by the female parent. When PH85-16 is the parent, it is mainly influenced by the male parent.The correlation of PTem between F1 and high parent and male parent is high. WhenZimai 12 is one of the parents, the PTem of F1 is mainly influenced by the low parent. If Lumai 14 is the parent, it is mainly influenced by the male parent. When the parent is PH85-16 or 924142, it is mainly influenced by the other parent, and when the parent is 924142, it is inclined to the high parent. When the parent is Sn2618, it is mainly influenced by the male parent.The correlation of SB between F1 and female parent and high parent is high, and the SB of F1 is inclined to the high parent. When PH85-16 is one of their parents, the SB of F1 inclined to the low parent. If Sn2618 is the parent, it is mainly influenced by the other parent, and is inclined to the low parent.The correlation of BD between F1 and their parents is low, the BD if F1 there is a random show. If Zimai 12 is one of the parents, the BD of F1 is mainly influenced by the other parent. When the parent is Lumai 14 or 924142, it is mainly influenced by male parent. As PH85-16 is the parent, it is mainly influenced by male parent, and it is inclined to the high parent.Among the hybrid vigor of RVA, there is no evident one. But the hybrid vigor of PV, TV, FV, SB to low parents are clear. The hybrid vigor of PTem is low.
