In a measure, also, varieties of crops have been produced to suit diffei-ent types of soil, to vary in their fertilizer requirements, resistance to excessiye wet or dry weather, etc. Plants resemble Parents. — In a general sense, a plant is like its parents. Jt is not true, howeyer, that seed from a nearly perfect ear of corn will, of necessity, produce only stalks haying perfect ears. A fine ear of corn may have been fertilized (pollenized) by one bearing a little nubbin. The nubbin may have been pollenized by the stalk having the fine eai-. In that case the nubbin would make as good seed as the fine ear, if the grains are as sound and individuall}' as large. Even if the fine ear is crossed with another stalk having a fine ear, and the nubbin witli a stalk having a nubbin, it is not at all likeh^ that tlie seed will be so widely different in productive power when planted as the parent ])lants were. Eacli grain has in it not only the strain of its immediate parents, l)ut of a hundred generations of })arents. One or two generations of nubbins, or even almost barren stalks as ancestors of one parent, caused by poor soil, poor culture, or dronght, will not be likely seriously to reduce tlie yield when planted, if good conditions are again provided.
