Abstract

       In order to determine the effect of three sowing dates (first June, 15th June, 30 June) on the performance of six new rice genotypes (Oryza sativa L.) are: (T85, LT2, HT1) were introduced from Vietnam, and (MRBF-0174, MRFA-01-7-11, MRBF-0167), were invented from Al-Mishkhab Rice Research Station, in addition of  Jasmine local variety as check. Factorial experiment was conducted by using randomized complete block design (RCBD) with three replications in Al-Mishkhab Rice Research Station / Agricultural Researches office at Iraq during summer season 2014. Measured the days number of 50% flowering, plant height, panicle length, grains number per panicle, panicle number per m², grain yield, and 1000-grain weight. The results indicated that the significant differences for all traits at the level of 5% probability. The T85 was increased in 1000-grain weight (23.01)g, panicle number per m² (389.6) biological yield (17764) kg.hˉ¹, and grain yield (7667) kg.hˉ¹, while the MRFA-01-7-11 was increased in panicle length and plant high reached to (28.56) cm and (136.89) cm respectively. The highest grain yield with second sowing date reached to (6302) kg.hˉ¹, lowest unfertile grain (9.05%), and higher panicle number (328.1).
