Determining relationships between morphological, some anatomical traits and phenoles realated to insect resistance in two crosses cotton [electronic resource].

Includes references.

This invstigation aimed to study the importance of morphological and anatomical traits with total phenols in leaves and bolls for insect resistance and evaluate the hybrids of Giza 88 okra leaf shaped and cultivar Giza 88 with promising cross [(G.84 x(G.70 xG.519) x pima 62 l]The trial was conducted at Sakha Research Station during 2010 and 2011 summer seasons. The results indicated that the leaves of line G.88 okra leaf characterized by narrow lobes while Giza 88 was wider lobes. Giza 88 Characterized by increase for size of leaf nectaries and No. of bolls nectaries. Total phenols in leaf was high for the parent Giza 88 okra leaf, while F1 was intermediate between its two parents. The anatomical study revealed narrow difference between anatomy structural of the two parents Giza 88 and line Giza 88 okra for leaves. Anatomical features were observed, firstly the extension of the palisade tissue towards the mid vein of two parents exhibited palisade tissue, secondly the presence one in G.88 okra while G.88 had two small reverse oriented bundles separated. The F1 had not small reverse oriented bundjes.
