1. Pods set in both types of crosses (2n C.G.×4n C.G. and 4n C.G.×2n C.G.). Five pods are found to reach up to maturity in case of 2n C.G.×4n C.G. Pods set in case of the second cross shed within a week. 2. In 2n D 154×4n D 154 and its reciprocal crosses no pod sets at all. 3. The cross pods (2n C.G.×4n C.G.) are shorter than those of both parents. 4. In 2n C.G.×4n C.G. and its reciprocals, the egg is found to be fertilized within 24 hours. But in 2n D 154×4n D 154 and its reciprocals, pollen tube does not reach the ovule in one day. 5. Complete fusion of the egg and the sperm in case of 2n C.G.×4n C.G. and its reciprocals is not observed even in two days. But in case of 2n D 154×4n D154 and its reciprocals no fertilization is observed. 6. Degeneration of ovules starts on the 3rd day in case of 4n C.G.×2n C.G. In 2n D 154×4n D 154 degeneration starts on the 2nd day and in its reciprocal degenerating ovules are marked on the 3rd day. © 1960 Martinus Nijhoff.
