In selecting plants or varieties for higher yields, breeders are generally guided by certain external features that are associated with productivity. In rice, for example, selection is based on characters like tillering, number of ears per plant, length of ears and twinning of the grains at the tips of the ears. Another variation observed in rice is with reference to the depth of the green colour of the foliage. Such difference in depth of colour is observed between different varieties and also between strains isolated within a variety.
