Root-shoot variability in sweet corn inbreds under water stress conditions

The present study was carried out at Faculty of Agriculture, SKUAST-Kashmir, Wadura, Sopore to evaluate sweet corn inbreds under drought and irrigated conditions. The results obtained revealed that mean root depth recorded under drought and irrigated conditions were 109.8cm and 102.9cm respectively. BIOL-23 (155 cm) recorded highest root depth under drought conditions while as BIOL-23 (130) recorded highest root depth under irrigated conditions. The root volume was having mean value of 11.42 cm3 and 21.19 cm3 under drought and irrigated conditions respectively with highest value recorded in BIOL-21 (37.5 cm3) under drought conditions and BIOL-23 (40.15 cm3) under irrigated conditions. The root traits showed significant results for genotypes as well as for water regimes. The number of leaves statistically showed the non-significant results under both drought and irrigated conditions. The shoot height recorded mean value of 90.58cm and 136.67cm for drought and irrigated conditions respectively with BIOL-62 (114.5cm) and BIOL-8 (181cm) having highest shoot height under drought and irrigated conditions. The shoot traits were significant for shoot height only for genotypes whereas number of leaves and shoot weight were significant both under drought and irrigated conditions.
