Abstract<\/strong><\/p>\n\n\n\n

Five genotypes of local wheat: var. Alass24 (Shara No. 2,\nvar. Alass25 (Shara No. 154), Advanced line No. 35, Advanced line No. 42,\nAdvanced line No. 12 and the Arabi variety were planted at Bani Matar region,\nAl-Qalis site in Yemen, between 18-7\/24 \nof  the years 2014 and 2015 under\nrainfed conditions. The results showed a significant variation among  genotypes in grain yield, biological yield,\nweight of 1000 grains, plant height, spike length, number of grains per spike,\nnumber of days to maturity, and harvest index. The variety Arabi and the two\ngenotypes., Alass25 (Shara No.154) and Advanced line\nNo.35 attained good yield compared to Alass24 genotype (Shara No.2), and the  averages were 2033, 2016, 1965 and 1514 kg\/ha respectively. The genotype\nAlass25 (Shara No.154) gave higher biological yield of 6891 kg\/ha, and higher\nspike length (8.6 cm) with increased seeds number per spike (48.8), while the\nharvest index was lower (29.3.%), on the other hand Arabi variety gave lower\nvalues in terms of biological yield (4914 kg\/ ha), length of spike (6.3 cm) and\nnumber of seeds per spike (17.4), while the harvest index was the highest\n(41.4), although both variety\/genotype gave high grain yields. A positive\ncorrelation was found between grain yield and 1000 kernel weight, while correlation\nbetween yield, plant height and number of days to maturity was negative. A 1000\nkernel weight positively correlated with both spike length  and number of grain per spike. The length of\nspike was positively correlated with number of seeds per spike and number of\ndays to maturity. Significant differences were found among genotypes for \u039413<\/sup>C in grain and \u039413<\/sup>C in leaves, the variety Arabic and\nAlass25 genotype (Shara No.154) attained higher values of \u039413<\/sup>C\ngrain and \u039413<\/sup>C leaves compared with others, the\nvalues were 14.24 and 13.66 for grains and 18.33 and 17.99% for leaves. Both\ngenotypes attained also the highest values of grain yield with highest harvest\nindex. This is as indicator of an effectiveness of Carbon Isotope\nDiscrimination (CID) as an efficient tool selection for high yielding variety\ncombined with drought tolerance for both rainfed system and areas where\nirrigation water is limited. Grain yield of a variety is an important trait\nwhen selection for drought condition is requested, it correlated positively and\nsignificantly with  number of seeds per\nspike and biological yield, while it correlated negatively with plant height\nand number of days to maturity. It was found also a positive correlation with \u039413<\/sup>C grain, while correlation was\nnegative with \u039413<\/sup>C leaves. This means, breeders can\nselect the genotype that has a higher \u039413<\/sup>C grain for\ndrought conditions. <\/p>\n\n\n\n
