The Inheritance or Sub-red Plant Mutant from Upland Cotton.

A new mutant in upland cotton was reported and named the sub-red plant by Chen Xu-sheng in 2004. The results of observations on the sub-red plant showed that there were obvious differences among the sub-red plants the classic red plants and the normal green plants at every stage. As concerned cotyledon and neonatal color the classic red plant's was sanguine the normal green plant's was green while the sub-red mutant's was slightly red. During the flowering stage there was visible distinctness among the three genotypes as following:(1) The color of the intraday flower was different the normal green plant's was white but the sub-red mutant plant's was ponceau which surpassed the classic red plant's, (2) The leaf color of classic red plant was red the normal green plant's was green while the sub-red mutant's was slightly red and its leaf color gradated near green as the leaves grew up gradually.
