Özet:

A field experiment was conducted during the years 2016- 2017, 2017-18 and 2018-19 to evaluate the performance of 13 elite Isabgol genotypes for commercial cultivation under semi-arid conditions of Haryana at Research Farm of MAP Section, Department of Genetics and Plant Breeding CCS Haryana Agricultural University, Hisar. The results on the basis of mean performance over three years seed yield data of all 13 genotypes revealed that, the highest seed yield (kg/ha) was found in genotype HI-137 (307.89 kg/ha) and closely followed by HI-135 (307.86 kg/ha), which were significantly superior to all the genotypes. Some other genotypes like Niharika (290.82 kg/ha) and HI-133 (293.13 kg/ha) also produced good yield. Lowest seed yield was recorded in genotype HI-136 (189.94 kg/ha). On the basis of average of three years data, it is consolidated that the genotype, HI-135 had the longest spike (5.55 cm) followed by HI-131 (5.38 cm), HI-137 (5.26 cm) and HI-138 (5.16 cm). Likewise, HI-137 was also recorded the maximum number of florets/spike (47.71 florets/ spike) closely followed by GI-2 (46.52 florets/spike), Niharika (46.11 florets/spike) and HI-135 (44.36 florets/spike). Under different environment conditions, the elite genotypes, HI-137 (307.89 kg/ha) and HI-135 (307.86 kg/ha) were able to perform better and were significantly superior to all other genotypes, therefore, these genotypes may be recommended for cultivation in semi-arid region of Haryana after further testing their preference over time and space.
