Relationship between Flower Opening in Six Cotton Cultivars and Their Progeny to Pollen Dehydration Tolerance

Table 2

Comparison of observed flower phenotypes and predicted segregation phenotypes for a dominant trait of F₂ plants from bidirectional crosses between Phytogen 72 (PHY) and Stoneville 474 (STV) used as male (m) and female (f) parents.

Populations	Observed < 2-1	Observed 2–4	Predicted	Predicted	Total
F2 STVf × PHYm^†	19	74	24	69	93
F2 PHYf × STVm^‡	92	39	98	33	131

Note: Mendelian inheritance rations for one gene for the test of goodness of fit, ^†open flower (OPFL) predicted 1 : closed flower (CLFL) predicted 3 and ^‡OPFL 3 : CLFL 1.
