Zea mays ssp. parviglumis is the progenitor of maize and assume to have tolerance against various biotic and abiotic stresses. It grows without human intervention in Southern Mexico at the bank of Balsas river and maintains sufficient genetic diversity that can help in maize diversification and domestication of wild alleles. To develop the uniform near to homozygous line the maize inbred parent DI-103 (seed parent) was crossed with teosinte (pollen parent) to produce F₁s followed by one generation of backcrossing with DI-103. Subsequently, selfing was done to produce 126 BC₁F₃ and BC₁F₄ generations, which were evaluated in the Kharif 2017 and Rabi 2017–2018 for 12 characters. Large variations were observed for all the characters in BC₁F₃ and BC₁F₄ generations of teosinte derived maize population and depicted by box-plots. In addition to above, some lines with unique features such as protogynous behaviour in 76 lines, short ASI (0–1 days) in 20 lines and > 3 ears per plant in 21 lines were noted in both BC₁F₃ and BC₁F₄ generations. Allelic reshuffling between maize and teosinte genome is assume as a probable cause for wide range of variation among the lines. For inheritance of anthesis-silking interval and ear/plant in both the generations and for silking duration in BC₁F₃ generation complementary gene interaction is involved whereas for days to 50% anthesis, 50% silking duplicate gene interaction is involved in BC₁F₄ generations. The results of the investigation are unique and promising and it further indicates that teosinte can be used efficiently as a donor in diversification of maize germplasm and domestication of wild alleles particularly of those which are adaptive in nature and comply with climatic resiliency.

玉米 SSP。 parviglumis 是玉米的祖先，假定对各种生物和非生物胁迫具有耐受性。它在墨西哥南部巴尔萨斯河岸的人工干预下生长，并保持足够的遗传多样性，有助于玉米多样化和野生等位基因的驯化。为了开发接近纯合系的均一品系，将玉米自交亲本 DI-103（种子亲本）与 teosinte（花粉亲本）杂交以产生 F ₁ s，然后与 DI-103 进行一代回交。随后，进行了自交以产生 126 BC ₁ F ₃和 BC ₁ F ₄世代，这些世代在 Kharif  2017 和 Rabi  2017-2018 12 个字符。在 BC ₁ F ₃和 BC ₁ F ₄代的 teosinte 衍生的玉米种群中观察到所有性状的巨大变化，并由箱线图描述。除上述外，在 BC ₁ F ₃和 BC ₁ F 中均发现了一些具有独特特征的品系，例如 76 个品系中的原始行为、20 个品系中的短 ASI（0-1 天）和 21 个品系中每株 > 3 穗₄世代。玉米和 teosinte 基因组之间的等位基因改组被认为是品系之间广泛变异的可能原因。对于 BC ₁ F ₃代中的花期-落丝间隔和穗/植物的遗传和抽丝持续时间，涉及互补基因相互作用，而对于开花至 50% 的天数，BC ₁ F 中涉及 50% 的抽丝重复基因相互作用₄代。调查的结果是独特的和有希望的，它进一步表明，在玉米种质多样化和野生等位基因的驯化，特别是那些具有适应性和适应气候弹性的野生等位基因的驯化中，可以有效地利用 teosinte 作为供体。
