Abstract

: NDLH 2051-1 has a mean seed cotton yield potential of 1590 kg ha -1 and has been singled out for commercial cultivation in the south and central zones of India by the Regional Agricultural Research Station, Nandyal, India. This cultivar represents an essential contribution to sustainable cotton produc tion in India. adaptable to the rainfed agricultural system. The program focuses on yield, fiber quality, and biotic and abiotic stress tolerance ability. The variety NDLH 2005-4 (Nandyal Hirsutum 2005-4) was developed with a mean seed cotton yield potential of (1380 kg ha -1 ) and sucking pest tolerance with mean jassid injury grade (2.2), jassids/3 leaves (8.1), white flies/3 leaves (12.2), and aphids/3 leaves (48.7). To improve productivity, it is essential to develop cultivars with more significant yield potential, better fiber traits, and higher pest and disease tolerance than the existing varieties. Considering the importance of production and productivity of cotton crop in India under rainfed farming, the presen tstudy was undertaken to develop acultivar with high-yield potential, superior fiber traits, and biotic and abiotic stress tolerance suitable for rainfed conditions in India. We report a new variety, NDLH 2051-1 (Nandyal Hirsutum 2051-1), that possesses high mean seed cotton yield, high-quality fiber traits, and sucking pest tolerance to jassids, whiteflies, thrips, and aphids. This cultivar represents a fundamental contribution to cotton production in India’s central and southern zones.

NDLH 2051-1:一种高产、耐吸害的棉花品种

: NDLH 2051-1的平均棉籽产量潜力为1590公斤公顷，已被印度南迪亚尔地区农业研究站挑选出来用于印度南部和中部地区的商业种植。这个品种代表了印度可持续棉花生产的重要贡献。适应雨养农业系统的。该计划的重点是产量，纤维质量，以及生物和非生物抗逆性。培育了NDLH 2005-4 (Nandyal Hirsutum 2005-4)品种，籽棉平均产量潜力(1380 kg hm2 -1)，耐吸虫，平均茉莉伤害等级(2.2)，茉莉/3叶(8.1)，白蝇/3叶(12.2)，蚜虫/3叶(48.7)。要提高产量，必须培育产量潜力更大、纤维性状更好、病虫害耐受性更好的品种。考虑到印度旱作条件下棉花产量和生产力的重要性，本研究旨在开发适合印度旱作条件的高产潜力、优良纤维性状和生物和非生物抗逆性的棉花品种。我们报道了一个新品种NDLH 2051-1 (Nandyal Hirsutum 2051-1)，它具有较高的平均棉籽产量，优质的纤维性状，并且对茉莉、粉虱、蓟马和蚜虫具有抗性。该品种对印度中部和南部地区的棉花生产做出了重要贡献。
