Pre-breeding for diversification of primary gene pool and genetic enhancement of grain legumes

Abstract: The narrow genetic base of cultivars coupled with low utilization of genetic resources are the major factors limiting grain legume production and productivity globally. Exploitation of new and diverse sources of variation is needed for the genetic enhancement of grain legumes. Wild relatives with enhanced levels of resistance/tolerance to multiple stresses provide important sources of genetic diversity for crop improvement. However, their exploitation for cultivar improvement is limited by cross-incompatibilit… Show more

“…Since the 1970s, grain legume breeding focused on disease resistance, growth habit and duration in relation to increasing yields [63]. It was only post-2000 that characteristics such as drought and heat-stress tolerance and environmental adaptability (genotype × environment) became topical [64,65]. Recently, pre-breeding of some minor grain legumes indigenous to semi-and arid tropics (e.g., cowpea, pigeon pea, and chickpea) has come into light for their adaptation to drought and heat stress.…”

“…Akan tetapi, tidak semua SDG dapat langsung dimanfaatkan sebagai sumber gen untuk proses pemuliaan, sehingga diperlukan kegiatan tahap awal untuk mendukung proses pemuliaan (pra-pemuliaan atau pre-breeding) untuk mengoptimalkan pemanfaatan SDG yang dipersiapkan untuk perakitan varietas unggul baru. Pra-pemuliaan meliputi identifikasi dan evaluasi karakter yang diinginkan, hibridisasi, studi genetik pewarisan sifat, pencarian marka molekuler terkait karakter yang diinginkan, dan sekuensing genom atau gen yang diinginkan (Sharma et al, 2013). Keragaman SDG di bank gen dapat dimanfaatkan untuk keperluan pra-pemuliaan dalam merakit varietas baru atau memperbaiki secara genetik suatu varietas agar lebih produktif (Kumar dan Shukla, 2014;Sharma et al, 2013).…”

Keragaman SDG di bank gen dapat dimanfaatkan untuk keperluan pra-pemuliaan dalam merakit varietas baru atau memperbaiki secara genetik suatu varietas agar lebih produktif (Kumar dan Shukla, 2014;Sharma et al, 2013). Dalam upaya pengembangan varietas baru tahan/toleran terhadap hama dan penyakit maupun adaptif terhadap lingkungan informasi keragaman genetik sangat diperlukan dalam kegiatan pra-pemuliaan (Gorjanc et al, 2016).…”
