Nodes above White Flower (NAWF): an Indicator of Earliness in Cotton
Rehana Anjum, A. R. Soomro and M. A. Chang

Abstract: The study was conducted on four advance cotton strains and one commercial cultivar developed by CCRI Sakrand to establish the early maturing variety during 1997 cotton season. The results demonstrated that 58 days after planting (DAP) all the cultivars developed more than 8 NAWF with non-significant difference in their growth and development. However at 65 and 74 DAP significant difference was observed. Commercial cultivar CRIS-9 developed highest number (7.9) of NAWF at 65 DAP and (5.45) at 74 DAP, while CRIS-133 developed lowest number (6.5 and 4.15) of NAWF during the same period. Similarly CRIS-52, CRIS-133 and CRIS-134 developed less than 5-NAWF at 74 DAP suggesting that these cultivars ceased to grow further and moved towards maturity. CRIS-133 was observed as early where as CRIS-9 as late maturing variety in the test.
