In chickpea a multi-parent advanced generation intercross (MAGIC) population was developed using eight parents that are improved varieties and widely adaptable breeding lines. The main objective was to enhance the genetic diversity and bring novel alleles for developing superior chickpea varieties. The development scheme involved a sequence of 28 two-way, 14 four-way and 7 eight-way crosses, followed by bulking of final F₁ plants. From F₂ generation onwards single plants were grown as progenies and advanced to F₈ by single seed descent method. The finally developed 1136 MAGIC lines were phenotyped under rainfed (RF) and irrigated (IR) conditions for 2 years (2013 and 2014) under normal season, and one year under heat stress (HS) condition (summer-2014) in field to estimate the genetic diversity created among these lines. Under RF-2014, RF-2013, IR-2014, IR-2013 and S-2014 seasons 46, 62, 83, 50 and 61 lines showed significantly higher grain yield than the best parent, respectively. Similarly, 23 and 19 common lines were identified under RF and IR conditions over two years and no common line was identified between RF/IR and HS conditions. Preliminary evaluation showed a large variation among MAGIC lines for flowering time (34–69 days), maturity (80–120 days), plant height (23.3–65 cm), grain yield (179–4554 kg/ha), harvest index (0.10–0.77) and 100 seed weight (10–45 g) under RF and IR conditions. Several genotypes with higher grain yield than the best check under heat stress were identified. These MAGIC lines provide a useful germplasm source with diverse allelic combinations to global chickpea community.

在鹰嘴豆中，使用 8 个作为改良品种和广泛适应性育种系的亲本开发了多亲代互交 (MAGIC) 种群。主要目标是提高遗传多样性并为开发优良鹰嘴豆品种带来新的等位基因。开发计划包括 28 个双向杂交、14 个四向杂交和 7 个八向杂交序列，随后是最终 F ₁植物的膨胀。从 F ₂代开始，单株植物作为后代生长并发展为 F ₈单种子下降法。最终开发的 1136 个 MAGIC 品系在雨养 (RF) 和灌溉 (IR) 条件下进行了 2 年（2013 年和 2014 年）正常季节，以及一年在热应激（HS）条件下（2014 年夏季）的田间表型，以估计在这些品系之间创造的遗传多样性。在 RF-2014、RF-2013、IR-2014、IR-2013 和 S-2014 季节，46、62、83、50 和 61 品系的籽粒产量分别显着高于最佳亲本。同样，在两年内在 RF 和 IR 条件下确定了 23 和 19 条共同线，并且在 RF/IR 和 HS 条件之间没有确定共同线。初步评估显示，MAGIC 品系在开花时间（34-69 天）、成熟度（80-120 天）、株高（23.3-65 厘米）、谷物产量（179-4554 公斤/公顷）、收获指数（ 0.10-0。77) 和 100 个种子重量 (10–45 g) 在 RF 和 IR 条件下。鉴定了几种基因型，其谷物产量高于热应激下的最佳检查。这些 MAGIC 品系为全球鹰嘴豆群落提供了具有多种等位基因组合的有用种质来源。
