Unveiling safflower yield, oil content, water use efficiency, and membrane stability under differential irrigation regimes

Safflower is a drought tolerant oilseed crop with great promise to be cultivated in the marginal lands of subtropical regions. Sustainable seed yield with better oil content and its quality will be dependent over crop tolerance and water use efficiency (WUE) under current scenario of global climate...

Description
Summary:Safflower is a drought tolerant oilseed crop with great promise to be cultivated in the marginal lands of subtropical regions. Sustainable seed yield with better oil content and its quality will be dependent over crop tolerance and water use efficiency (WUE) under current scenario of global climate change. In this regard, experiment was planned under randomized complete block design (split plot arrangement) where treatments comprised of 06 USDA safflower accessions and 3 differential irrigation regimes i.e. W 0 , W 1 , and W 2 . Exotic safflower accessions namely PI-198990, PI-314650 (non-spiny), and PI-210834 (spiny) were emerged as drought tolerant due to their higher values of (WUE), irrigational water use efficiency (IWUE), and membrane stability index (MSI). Same accessions also had high seed oil and oleic acid contents and were later in maturity when compared with other accessions. PI-208677 for accumulated high linoleic acid under W 0 regime. Correlation of seed yield of safflower accessions was significant for thousand seed weight, seeds per head, plant height, and days to maturity, while oil content had positive correlation with thousand seed weight, seed yield, MSI, and WUE.
