dc.description.abstract | Sesame (Sesamum indicum L.), one of the oldest oil seed crops of the world is mostly grown by small and marginal farmers of arid and semi-arid regions of India. The productivity of sesame in major sesame growing states ranges from74 kg ha-1 in Rajasthan to 291 kg ha-1 Gujarat, and is far below from national average (368 kg ha-1). Low yield in farmer’s fields often results because of low level of inputs and frequent soil moisture deficit. Under these circumstances, problems of low yield in resource poor farmer’s field remain a major challenge. The present study aimed at identifying the high yielding sesame cultivars and the potential breeding resources for low input agriculture in arid ecosystems. Seventeen released cultivars collected from different agro climatic zones of India were evaluated under low input conditions (no fertilization, irrigation and pest management ) using RBD with three replications at CAZRI, Regional Research Station, Bhuj, Gujarat during kharif 2010-11. The result of the analysis of variance for plant height (cm), days to 50 % flowering and maturity, number of seeds/capsule, first capsule height (cm), capsule length and width (mm), number of capsules/plant, seed weight/capsule (mg), dry capsule weight (mg), biomass yield (kg ha-1) and seed yield (kg ha-1) indicated that genotypic differences for these traits were highly significant (P <0.01). However, significant genetic variation (P <0.01) among varieties was observed for number of efficient branches/plant, capsule filling rate (%) and harvest index only. Cultivar Purva 1 had the shortest maturity period with 74 days, whereas PB Til 1 had an average of 71 capsules per plant. Capsule filling rate was the highest (54%) in PT-64. Three cultivars namely, Murg-1, PT-64 and PB Til 1 gave the maximum grain yield of 570, 559 and 540 kg ha-1, respectively. Thus, it could be concluded that these three genotypes may be further evaluated over the years for yield response in resource poor farmer field conditions. Based on cluster analysis, maximum dissimilarity was observed between the varieties PT 64 and C 1013 and PB Til 1 with the distance value of 6.88 and 6.05, respectively. These widely divergent genotypes could be further evaluated for their breeding values as parents and could be exploited in sesame crop improvement for low input agriculture. | en_US |
