Differential Behavior Of Teosinte(Zea Mays Parviglumis) Progenitor Of Maize Under Water Logging Conditio

Abstract

Zea mays ssp. parviglumis is the most probable progenitor of cultivated maize and assume to have tolerance against excess moisture content, that has not been reported so far so there is need of evaluation of parviglumis under waterlogged condition, For this teosinte were evaluated in two replication in each condition i.e., normal irrigated condition and water logged condition for thirteen morphological characters including yield contributing traits. Five randomly selected competitive plants for each plot were used for recording observations. The experimental data recorded for various characters were analyzed by using R software. Out of thirteen characters, six were significantly differ between these two condition as p value for plant height was 0.0127 *, for flag leaf length was 0.0127 *, for flag leaf width 0.0448 *, for total number of ears/plant was found 0.0204 *, for days to silk emergence and days to anthesis was 0.0136 *. In the current study it has been found that parviglumis show absence of adventitious root formation, lateral branching were absent, tassel with sparse density and thinner stem were produced under water logged condition and there is reduced level of yield related traits were exhibited. Therefore,teosinte was found susceptible to waterlogged condition.
